HP Officejet Pro 8500
Printer tries to align itself after every print job, but fails
Ink streaking somewhat despite recently replacing print cartridges and heads and multiple printhead cleaning cycles
Calibrated linefeeds
What else can I attempt without tossing the entire printer?

So you've already tried cleaning and calibrating the linefeed. Are the ink levels ok?
An 'Alignment failed' Error Message Displays on the Printer Control Panel

    Hi James
    This Ask the Expert session may not be the right place to show you all the essential steps for how the workflow can be related to task library to achieve your initial setup flow chart, and onboarding a new client.
    However, I can briefly walktthrough "Client blade Provisioning" task so it might give some idea and how you can go about.
    Assumption :  the infrastructure used in the following examples consists of:
    -  Vmware VCenter
    -  Cisco UCS
    -  NetApp ONTAP controlled storage
    To be able to provision Cisco UCS blade server in automated fashion, you need to create and define the below UCS entities beforehand.
    - Create UCS Organisation
    - Create UUID Pool
    - Create MAC Address Pool
    - Create WWNN Pool
    - Create WWPN Pool
    - Create vHBA Templates
    - Create vNIC Templates
    - Create UCS Policy vHBAs
    - Create UCS Policy vNICs
    - Create Storage Policy
    - Create Network Policy
    - Create SAN Boot Policy
    - Create LAN Boot Policy
    Once you create all the policy above, you are good to set up a workflow container for the client blade provisoining.
    1. Create UCS Service Profile
    - Add a ‘Create UCS Service Profile’ workflow task and select ‘Map to User Input’ for ‘Service Profile Name’. Select the ‘Service Profile Name’ dropdown as created when the workflow container was created.
    - ‘Create UCS Service Profile’ inputs. Ensure that Storage_Policy, Network_Policy, Boot_Policy_LAN and Boot_Policy_SAN entries are correct.
    - Once this is done , you can move to SAN zoning.
    2. Configure SAN Zoning
    - In this step, a new workflow task will be created in order to configure SAN zoning. Rather than use a specific user input for this task, output variables from the previous ‘Create UCS Service Profile’ workflow task will be used as input items for this task.
    - Open the workflow and search for the workflow task ‘configure san zoning’. Drag the storage workflow task into the work area and map the following user inputs.
    Create Flexible Volume
    - Create a ‘Create Flexible Volume’ workflow task in order to build a NetApp flexible volume and provision it for the required size.
    - Once again, reconfigure the workflow such that the success criteria from the ‘Configure SAN Zoning’ workflow task proceeds to ‘Create Flexible Volume’.
    Create LUN
    - Using the NetApp ONTAP ‘Create LUN’ workflow task, create a LUN located within the volume created during the previous step. In order to do this, map the Volume Name user input to the output from the previous ‘Create Flexible Volume’ workflow task.
    - Next, enter the LUN details, ensuring that the configured size is less than that of the volume created in the previous step.
    - As before, re-map the workflow designer flow so that the successful output of the Create Flexible Volume workflow task flows into this task.
    3. Create Initiator Group
    - Create a ‘Create Initiator Group’ workflow task in order to build a NetApp ONTAP Initiator Group. Map the ‘Filer Identity Name’ attribute to the OUTPUT_FILER_IDENTITY output variable as supplied by the ‘Create NetApp Flexible Volume’ workflow task as created earlier in this workflow.
    - Once again, modify the the workflow designer flow so that the successful output from ‘Create LUN’ flows into ‘Create Initiator Group’
    4. Add Initiator to Initiator Group
    - Create an ‘Add Initiator to Initiator Group’ workflow task and map the ‘Initiator Group Name’ entry to the OUTPUT_IGROUP_IDENTITY output variable from the ‘Create NetApp Initiator Group’ workflow task and map the ‘Initiator Name’ entry to the SP_VHBA1 output variable from the ‘Create UCS Service Profile’ workflow task created earlier in this flow.
    - Repeat this task for in order to add initiator name entry for SP_VHBA2. Once done, re-map the successful output from the two Create Initiator Group workflow tasks so that they flow into each other as follows:
    - Move onto the next step in order to map the created LUN to the initiator group.
    And the rest of steps are fairly similar to above. Create a Workflow and map the User Input Mappings".
    5. Map LUN to Initiator Group
    6. Modify UCS Boot Policy LUN ID
    7. Select UCS Server
    8. Associate UCS Service Profile
    9. Power On UCS Server
    10. Modify UCS Service Profile Boot Policy
    11. Add VLAN to Service Policy
    12. Disassociate UCS Service Profile
    13. Wait for Specified Duration
    14. Associate UCS Service Profile
    15. Power On UCS Server
    16. Register Host with VCenter
    regards

    Hi Anurag,
    Thanks for your questions.
    1:Is there change in DB architecture as CUIC is the only option as compared to previous linux version UCCX ?
    I assume this is from the tables regarding historical data. The database schema essentially remains the same since UCCX 9.0 had CUIC too and we had a seperate DB Space for CUIC and we still continue with that. The traditional historical tables remain and the replication process remains the same too.
    2:Is there any version change for Linux OS used as VOS,
    The Linux version is Red Hat Linux 5. To be precise:
    [root@uccx10pub /]# cat etc/redhat-release
    Red Hat Enterprise Linux Server release 5.7 (Tikanga)
    3:Is there any API architecture change in UCCX 10 from previous releases ?
    I can answer this more of an overview. The only enhancement in the API side is the introduction of REST API step in the script editor. You can now make REST calls from the script and this ofcourse opens up a whole new world of possiblities.
    4:Since from UCCX 10 , we can only use either CAD or Finnesse at one  time, whats the impact of changing this after some time in production,  let say , i used CAD for 2 months and then i decided to move to Finesse,  whats the impact ? or is it a smooth change as switching CUIC and HRC  in previoius release ?
    For the scenario you mentioned, there is absolutely no problem. The point to note is that the Finesse services are activated/deactivated but the CAD desktop services are ALWAYS running. The only condition to keep in mind is that you can use ONLY ONE type of agent desktop at any time.  Also if Finesse is not used and CAD operations are used extensively, it is advisable to shutdown the Finesse service.
    5:Is 3rd Party UCS hardware supported by UCCX 10 instead of using Cisco manufactured UCS , can i use HP hardware for Virtualisation ?
    Yes, it can be used. This is something called as "Third party specs based specification". The most important things seen for compatibility are:
    Inter CPU Model
    It it is on thVMWare Hardware Compatibilty List
    You can get more information about this on the "Can I use this server?" section of UC Virtualized Hardware page:
    http://docwiki.cisco.com/wiki/UC_Virtualization_Supported_Hardware#.22Can_I_use_this_server.3F.22
    6:Is Host name change supported?
    Yes, the hostname change is supported. The prcocedure is documented in the UCCX 10.0 Administration Guide:
    http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_10_0/configuration/guide/UCCX_BK_W1AF9DDD_00_uccx-admin-guide-10.0.pdf (Pg 168)

  • Ask the Expert: FSPF Concepts and Troubleshooting in Cisco SAN Environments

                With Upinder Sujlana
    Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about FSPF, VSAN interaction, load balancing, and troubleshooting with Upinder Sujlana.
    According to the FC-SW-2 standard, Fabric Shortest Path First (FSPF) is a link state path selection protocol. FSPF keeps track of the links on all switches in the fabric and associates a cost with each link. FSPF tracks the state of links on all switches in the fabric, associates a cost with each link in its database, and then chooses the path with a minimal cost. The cost associated with an interface can be administratively changed to implement the FSPF route selection. Upinder will discuss Cisco's implementation of FSPF.
    Upinder Sujlana is a customer support engineer for Cisco's SAN TAC team based in San Jose, CA. He has worked in the TAC for the past five years with a focus on WAN technologies (L2TP, T1, T3, SCE 2K, 8K) and data center technologies such as MDS; Cisco Nexus 7000, 5000, and 2000; FCoE; and FC. Prior to joining the TAC, Upinder was a Java client-side programmer for an NMS startup company and then transitioned to network testing for a cloud company. He holds a master's degree in electrical engineering from Santa Clara University and has CCIE certification (no. 37318) in routing and switching. These days he is enthusiastic about Python programming. 
    Remember to use the rating system to let Upinder know if you have received an adequate response. 
    Upinder might not be able to answer each question due to the volume expected during this event. Remember that you can continue the conversation in Data Center community,  sub-community, Storage Networking   discussion forum shortly after the event. This event lasts through March 14, 2014. Visit this forum often to view responses to your questions and the questions of other community members.

    Hi Evan,
    You can use my favorite command as below to find out the cost and check what path traffic will take. Here is a example :
    switch1# show fspf internal route vsan 2
    FSPF Unicast Routes
    VSAN     Number          Dest Domain          Route Cost          Next hops
    1                   0x01(1)                    1000                  fc1/2
    1                   0xEF(239)                  1000                  fc1/1
    1                   0xED(238)                  2000                  fc1/1
                                                                         fc1/2
    This shows the total cost of all links.
    The next hop (238) has two interfaces. This indicates that both paths will be used during load sharing. Up to sixteen paths can be used by FSPF with a Cisco MDS 9000 Family switch.

  • Ask the Expert: One Management with Prime Infrastructure 1.2

    With Tejas Shah
    Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions from Cisco expert Tejas Shah on One Management with Prime Infrastructure 1.2 Combining the wireless functionality of Cisco Prime Network Control System (NCS) with the wired functionality of Cisco Prime LAN Management Solution (LMS),  Cisco Prime Infrastructure simplifies and automates many of the day-to-day tasks associated with maintaining and managing the end-to-end network infrastructure from a single pane of glass. The new converged solution delivers all of the existing wireless capabilities for RF management, user access visibility, reporting, and troubleshooting along with wired lifecycle functions such as discovery, inventory, configuration and image management, automated deployment, compliance reporting, integrated best practices, and reporting.
    Tejas Shah is a senior technical marketing engineer for Cisco Prime Infrastructure and Collaboration products. He has deployed Cisco Prime Collaboration Manager at various customer sites to help customers monitor and troubleshoot their video infrastructure. In addition, he is part of the Network Operations Center team at Cisco Live events for six years. Shah joined Cisco in 1995 and was in the Technical Assistance Center team supporting various network management system products for more than six years.
    Remember to use the rating system to let Tejas know if you have received an adequate response. 
    Tejas might not be able to answer each question due to the volume expected during this event. Remember that you can continue the conversation on the Wireless Mobility sub-community discussion forum shortly after the event. This event lasts through Sept 21, 2012. Visit this forum often to view responses to your questions and the questions of other community members.

    Raun, please see my responses inline:
    Can you go over the licensing method with Prime Infrastructure 1.2 please? 
    Raun, you can check out the following link for ordering guide at
    http://www.cisco.com/en/US/products/ps12239/products_data_sheets_list.html
    I currently have NCS and do NOT currently have LMS.  I know I can move to Prime Infrastructure through Cisco Product Upgrade Tool.  However, what I am confused about is do I still have to buy LMS to have LMS functionality in Prime Infrastructure 1.2? 
    ==> Not at all.  The converged product will give you basic management capability for routers and switches that LMS provided in this release.   Feature/Functionality will keep on growing with upcoming releases.
    If not, do the licenses I transfer into Prime Infrastructure 1.2 from NCS also work for devices to work under LMS? 
    ==> Licensing is different than NCS or LMS.  You don't have to transfer the license.  Each install of Prime Infrastructure will have a unique UID string on which the licenses are based.  A new license will be applied to the product.
    Mean, can my currently 350 licenses be used for AP's as in NCS and routers in the LMS portion of Prime Infrastructure 1.2?
    ==> I would recommend getting a total count of your wired and wireless devices and match the right SKU based on that.
    Hope this helps.. Let me know if you have any further questions,
    Tejas

    Hi Marcelo,
       Yes, there are some requirements for certificates in Expressway.
    Expressway Core (Exp-C)
    - Can be signed by either External or Internal CA
    - Better to use a cluster name even if you start with 1 peer in Exp-C cluster. In the future, if more peers are added, changes would be minimal.
    - Better to use FQDN of cluster as CN of certificate, this way the traversal zone configuration on Expressway-E won't require any change even if new peers are added to Exp-C cluster.
    - If CUCM is mixed mode, include security profile names (in FQDN format) as Subject Alternate Names
    - The Chat Node Aliases that are configured on the IM and Presence servers. They will be required only for Unified Communications XMPP federation deployments that intend to use both TLS and group chat. (Note that Unified Communications XMPP federation will be supported in a future Expressway release). The Expressway-C automatically includes the chat node aliases in the CSR, providing it has discovered a set of IM&P servers.
    - For TLS b/w CUCM, IM-P & Exp-C
      + If using self-signed certificates on CUCM, IM/P. Load Cisco Tomcat, cup, cup-xmpp certificates from IM-P on Exp-C. Load callmanager, Cisco Tomcat certificates from CUCM on Exp-C.
      + If using Internal CA signed certificates on CUCM, IM/P. Load Root CA certificates on Exp-C.
      + Load CA certificate under tomcat-trust, cup-trust, cup-xmpp-trust on IM-P.
      + Load CA certificate under tomcat-trust, callmanager-trust on CUCM.
    Expressway Edge (Exp-E)
    - Signed by External CA
    - Configured Unified Communications domain as Subject Alternate Name
    - If using a cluster, select FQDN of this peer as CN and FQDN of Cluster + this peer as Subject Alternate Name.
    - If XMPP federation is being deployed, enter the same Chat Node Aliases as entered in Exp-C.
    For more details, please refer to the Certificate Creation Guide for Cisco Expressway x8.1.1

    Hello Jason,
    Thank you very much for welcoming me to your expert discussion :) I feel to be in the right place, at the right time. Thank you also for answering question beyond your scope here, much appreciated. The information received will help me to go further as such I have submitted a 5 start rating for your first reply.
    That sounds promising about the LMS part so yes, I stay tuned and wait patiently.
    Ok, now let’s revert to the actual topic discussed here. Cisco Prime Service Catalog and Process Orchestrator solutions I have briefly read up on this on CCO (where elseJ) and picked out the following quote
    ---- Quote from the Cisco Prime Service Catalog Data Sheet
     Today’s end users want self-service and easy access to IT tools and services.
    Simultaneously, organizations are seeking ways to extend their cloud management
    platforms beyond self-service delivery of virtual machines and infrastructure resources
    while increasing their use of cloud-based solutions to enhance business agility and effectiveness.
    Cisco Prime™ Service Catalog offers tremendous benefits to organizations that want to unify the ways in
    which all types of IT services are ordered and fulfilled, not just infrastructure requests
    ---- un quote ---
    I try to understand what (at high level of course) happens in the back ground when an order is raised and which vendor solution your product can interact with.
    As mentioned in the quoted text, this service catalogue goes beyond the standard infrastructure.
    Let’s say, a user wants to deploy a new email services, or in your example,  extends or create a new web-portal (i.e. for HR to view and manage holiday, staff absence and benefits).
    Your solution will need to interact somehow with the 3rd party vendor application that is capable building such portal I believe.
    Without disclosing to many information, I assume the portal is linked to backend VM,s that spin up requested resources (and more magic of course). Perhaps I am mixing this up with another cisco product where a user can go on the portal and spin up virtual Firewalls, virtual Routers can be provisioned in now time.
    Out if interest; Is this product also known as Mozart? (project code within Cisco?)
    I hope query is ok.
    Best wishes

    Hello Robert,
    Apologies for a delayed response, some days get very hectic.
    In CallManager, we only define the SRST reference, and CUCM version and SRST version are independent of each other.
    The only thing, which is related and will change with CUCM upgrade is Phone F/w version.
    http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/compat/ccmcompmatr1.pdf
    You may just want to check your, phone f/w compatibility with the SRST version running on your ISR G1 Gateways:
    http://www.cisco.com/en/US/products/sw/voicesw/ps2169/products_device_support_tables_list.html
    For Example: SRST version 7.1
    http://www.cisco.com/en/US/prod/collateral/voicesw/ps6788/vcallcon/ps2169/data_sheet_c78-520521.html
    You may want to do some lab testing with CUCM 9.1 and an SRST supported f/w on your phones.
    If you decide to run the old Phone/F/w to support the SRST version, you may not be able to take advantage of new features.
    Also, you can try and upgrade your phones(Wih CUCM 9.1) and test them with your SRST version.
    It should work fine, but from a troubleshooting perspective, TAC may request you to come into a Cisco Supported combination.
    Please, let me know if this clarifies your doubt or we can have a quick phone call.
    Regards

    Tenaro,
    Additionally here are the most common login issues.  Unfortunately this includes items related to Presence implementation but I commented where we did not use these in our lab setup for CUCM Phone Capabilities only.  
    Login Issues
    Problem:
    Jabber Unable to Sign-in Through MRA
    Solution
    This can be caused by a number of things, a few of which are outlined below.
     1.  Collaboration Edge SRV record not created and/or port 8443 unreachable
    For a jabber client to be able to login successfully using MRA, a specific collaboration edge SRV record must be created and accessible externally. When a jabber client is initially started it will make server DNS SRV queries:
    _cisco-uds : this SRV record is used to determine if a CUCM server is available.
    _cuplogin : this SRV record is used to determine if an IM&P server is available.
    _collab-edge : this SRV record is used to determine if MRA is available.
    If the jabber client is started and does not receive an SRV answer for _cisco-uds and _cuplogin, and does receive an answer for _collab-edge then it will use this answer to try to contact the Expressway-E listed in the SRV answer.
    The _collab-edge SRV record should point to the FQDN of the Expressway-E using port 8443. If the _collab-edge SRV is not created, or is not externally available,  or if it is available, but port 8443 is not reachable, then the jabber client will fail to login.
     2.  Unacceptable or No Available Certificate on VCS Expressway
    After the jabber client has received an answer for _collab-edge, it will then contact the expressway using TLS over port 8443 to try to retrieve the certificate from the expressway to setup TLS for communication between the jabber client and the expressway.
    If the Expressway does not have a valid signed certificate that contains either the FQDN or domain of the Expressway, then this will fail and the jabber client will fail to login.
    If this is occurring, the you should use the CSR tool on the Expressway, which will automatically include the FQDN of the expressway as a Subject Alternative Name.
    MRA requires secure communication between the Expressway-C and Expressway-E, and between the Expressway-E and external endpoints.
    Expressway-C Server Certificate Requirements:
    The Chat Node Aliases configured on the IM&P servers. This is required if you are doing XMPP federation.  The Expressway-C should automatically include these in the CSR provided that an IM&P server has already been discovered on the Expressway-C.
    The names in FQDN format of all Phone Security Profiles in CUCM configured for TLS and used on devices configured for MRA. This allows for secure communication between the CUCM and Expressway-C  for the devices using those Phone Security Profiles.
    Expressway-E Server Certificate Requirements:
    All domains configured for Unified Communications. This includes the domain of the Expressway-E and C, e-mail address domain configured for Jabber, and any presence domains.
    The Chat Node Aliases configured on the IM&P servers. This is required if you are doing XMPP federation. 
    The MRA Deployment guide describes this in greater detail on pages 17-18. (http://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/config_guide/X8-1/Mobile-Remote-Ac...
    Note: In our lab for testing Phone Capabilities only, we did not include the Chat Node Aliases in the certificate as we were not using IM&P.
     3.  No UDS Servers Found in Edge Config
    After the Jabber client successfully establishes a secure connection with the Expressway-E, it will ask for its edge config. This edge config will contain the SRV records for _cuplogin and _cisco-uds. If these SRV records are not returned in the edge config, then the jabber client will not be able to proceed with trying to login.
    To fix this, make sure that _cisco-uds and _cuplogin SRV records are created internally and resolvable by the Expressway-C
    More information on the DNS SRV records can be found on page 10 of the MRA deployment guide for X8.1.1 (http://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/config_guide/X8-1/Mobile-Remote-Access-via-Expressway-Deployment-Guide-X8-1-1.pdf)
    Note: In our lab for testing Phone Capabilities only, we did not include the DNS SRV for _cuplogin.
     4.  The Expressway-C logs will indicate the following error: XCP_JABBERD  Detail="Unable to connect to host '%IP%', port 7400:(111) Connection  refused"
    If Expressway-E NIC is incorrectly configured, this can cause the XCP server to not be updated. If the Expressway-E meets the following criteria, then you will likely have this issue:
    Using a single NIC
    Advanced Networking Option Key is installed
    Use Dual Network Interfaces option is set to “Yes”
    To correct this problem, change the “Use Dual Network Interfaces” option to “No”
    The reason this is a problem is because the Expressway-E will be listening for the XCP session on the wrong network interface, which will cause the connection to fail/timeout. The Expressway-E listens on TCP port 7400 for the XCP session. You can verify this by using the netstat command from the VCS as root.
    Note: We used a Dual Network Interface Expressway for testing but were not using XCP, so this was not applicable to us.
     5.  VCE-E Server hostname/domain name does not match what is configured in the _collab-edge SRV.
    If the Expressway-E Server hostname/domain name does not match what was received in the _collab-edge SRV answer, the jabber client will not be able to communicate to the Expressway-E. The Jabber client uses the xmppEdgeServer/Address element in the get_edge_config response to establish the XMPP connection to the Expressway-E.
    This is an example of what the xmppEdgeServer/Address would look like in the get_edge_config response from the Expressway-E to the Jabber client:
    <xmppEdgeServer>
    <server>
    <address>ott-vcse1.vcx.cisco.com</address>
    <tlsPort>5222</tlsPort>
    </server>
    </xmppEdgeServer>
    To avoid this, make sure that the _collab-edge SRV record matches the Expressway-E hostname/domain name. Enhancement CSCuo83458 has been filed for this. 
    Note: This was one of our issues when we first setup.  We adjusted our Expressway-E to insure the below:
    System > Administration > System Name this was the FQDN
    System > DNS > System Host Name was the host portion of the FQDN
    System > DNS > Domain Name was the domain portion of the FQDN
    System > Clustering > Cluster Name (FQDN for Provisioning) was the FQDN
     6. Unable to log into certain IM&P servers. VCS logs say "No realm found for host cups-example.domain.com, check connect auth configuration"
    From the Expressway-E, go to Configuration -> Unified Communications -> IM&P Servers. Open each server and click "Save" again. Not sure exactly why this happens.
    Note:  This was N/A to our test and can be ignored with Phone Capabilities only.
    Thanks
    Fred

  • Ask the Expert: Hierarchical Network Design, Includes Core, Distribution, and Access

    Welcome to the Cisco® Support Community Ask the Expert conversation.  This is an opportunity to learn and ask questions about hierarchical network design. 
    Recommending a network topology is required for meeting a customer's corporate network design  needs in their business and technical goals and often consists of many interrelated components. The hierarchical design made this easier like "divide and conquer" the job and develop the design in layers.
    Network design experts have developed the hierarchical network design model to help to develop a topology in discrete layers. Each layer can be focused on specific functions, to select the right systems and features for the layer.
    A typical hierarchical topology is
    A core layer of high-end routers and switches that are optimized for availability and performance.
    A distribution layer of routers and switches that implement policies.
    An access layer that connects users via lower-end switches and wireless access points.

    Dear Leo,
    We are discussing the following without any product line, discussing the concept of hierarchical design, which will help you to take decision which model is better for you Two Layer or Three Layer hierarchical model.  
    Two-Layer Hierarchy
    In many networks, you need only two layers to fulfill all of the layer functions—core and aggregation
    Only one zone exists within the core, and many zones are in the aggregation layer. Examine each of the layer functions to see where it occurs in a two-layer design:
    Traffic forwarding—Ideally, all interzone traffic forwarding occurs in the core. Traffic flows from each zone within the aggregation layer up the hierarchy into the network core and then back down the hierarchy into other aggregation zones.
    Aggregation—Aggregation occurs along the core/aggregation layer border, allowing only interzone traffic to pass between the aggregation and core layers. This also provides an edge for traffic engineering services to be deployed along.
    Routing policy—Routing policy is deployed along the edge of the core and the aggregation layers, generally as routes are advertised from the aggregation layer into the core.
    User attachment—User devices and servers are attached to zones within the aggregation layer. This separation of end devices into the aggregation permits the separation of traffic between traffic through a link and traffic to a link, or device. Typically, it is best not to mix transit and destination traffic in the same area of the network.
    Controlling traffic admittance—Traffic admittance control always occurs where user and server devices are attached to the network, which is in the aggregation layer. You can also place traffic admittance controls at the aggregation points exiting from the aggregation layer into the core of the network, but this is not common.
    You can see, then, how dividing the network into layers enables you to make each layer specialized and to hide information between the layers. For instance, the traffic admittance policy implemented along the edge of the aggregation layer is entirely hidden from the network core.
    You also use the core/aggregation layer edge to hide information about the topology of routing zones from each other, through summarization. Each zone within the aggregation layer should have minimal routing information, possibly just how to make it to the network core through a default route, and no information about the topology of the network core. At the same time, the zones within the aggregation layer should summarize their reachability information into as few routing advertisements as possible at their edge with the core and hide their topology information from the network core.
    Three-Layer Hierarchy
    A three-layer hierarchy divides these same responsibilities through zones in three vertical network layers,
    Traffic Forwarding—As with a two-layer hierarchy, all interzone traffic within a three- layer hierarchy should flow up the hierarchy, through the layers, and back down the hierarchy.
    Aggregation—A three-layer hierarchy has two aggregation points:
    At the edge of the access layer going into the distribution layer
    At the edge of the distribution layer going into the core
    At the edge of the access layer, you aggregate traffic in two places: within each access zone and flowing into the distribution layer. In the same way, you aggregate interzone traffic at the distribution layer and traffic leaving the distribution layer toward the network core. The distribution layer and core are ideal places to deploy traffic engineering within a network.
    Routing policy—The routing policy is deployed within the distribution layer in a three- layer design and along the distribution/core edge. You can also deploy routing policies along the access/distribution edge, particularly route and topology summarization, to hide information from other zones that are attached to the same distribution layer zone.
    User attachment—User devices and servers are attached to zones within the access layer. This separation of end devices into the access layer permits the separation of traffic between traffic through a link and traffic to a link, or device. Typically, you do not want to mix transit and destination traffic in the same area of the network.
    Controlling traffic admittance—Traffic admittance control always occurs where user and server devices are attached to the network, which is in the access layer. You can also place traffic admittance controls at the aggregation points along the aggregation/core edge.
    As you can see, the concepts that are applied to two- and three-layer designs are similar, but you have more application points in a three-layer design.
    Now the confusion takes place in our minds where do we use Two Layer and where the Three layer hierarchical model.
    Now we are discussing that How Many Layers to Use in Network Design?
    Which network design is better: two layers or three layers? As with almost all things in network design, it all depends. Examine some of the following factors involved in deciding whether to build a two- or three-layer network:
    Network geography—Networks that cover a smaller geographic space, such as a single campus or a small number of interconnected campuses, tend to work well as two-layer designs. Networks spanning large geographic areas, such as a country, continent, or even the entire globe, often work better as three layer designs.
    Network topology depth—Networks with a compressed, or flattened, topology tend to work better as two-layer hierarchies. For instance, service provider networks cover large geographic areas, but reducing number of hops through the network is critical in providing the services they sell; therefore, they are often built on a two-layer design. Networks with substantial depth in their topologies, however, tend to work better as three-layer designs.
    Network topology design—Highly meshed networks, with many requirements for interzone traffic flows, tend to work better as two-layer designs. Simplifying the hierarchy to two levels tends to focus the design elements into meshier zones. Networks that focus traffic flows on well-placed distributed resources, or centralized resources, such as a network with a large number of remote sites connecting to a number of centralized Data Centers, tend to work better as three-layer designs.
    Policy implementation—If policies of a network tend to focus on traffic engineering, two-layer designs tend to work better. Networks that attempt to limit access to resources attached to the network and other types of policies tend to work better as three-layer designs.
    Again, however, these are simple rules of thumb. No definitive way exists to decide whether a network should have two or three layers. Likewise, you cannot point to a single factor and say, “Because of this, the network we are working on should have three layers instead of two.”
    I hope that this helps you to understand the purposes of Two Layer & Three layer Hierarchical Model.
    Best regards,
    Ahmad Manzoor

    The Discussion/Q&A is from November 24th through December 5th, 2014
    Cisco UCS, originally designed for the data center, is now optimized for branch and remote offices, point-of-sale, and smaller IT environments with Cisco UCS Mini. UCS Mini is for customers who need fewer servers (expandable to 15 servers) but still want the robust management capabilities provided by UCS Manager.  UCS 6324 Fabric Interconnect is main component which makes this solution possible on UCS 5108 Chassis with B200 M3 Blade Servers
    This solution delivers servers, storage, and 10 Gigabit networking in an easy-to-deploy, compact form factor.
