OK "Ask the Experts" - HP OJ5110 - SPITTOON GEARS!

OK Experts, Infoworld.com has been promoting:
HP experts to host online printer troubleshooting event
, so here is your chance to come through - and I've been waiting 4 years for this...
Just send me the ordering info (contacts, phone, email, part #'s and pricing) for either the set of gears
(especially the one that shucks its pathetic plastic peg), or a complete spittoon assembly for the Officejet 5110!
And I'm talking about pricing that's less the 25% of the retail of the printer - not some ridiculous $300+ insult.
Ball's in your court...
[text removed for privacy]

Seriously, I don't believe I could get the parts, and I worked on the product. I just saw a used one on Amazon for $75, so you could use that for parts. Sorry I don't have a better answer for you. Regards, CF PS You ought to remove your email from your post, in case spam harvesters troll our site.
I work for HP and hope to make your day Sproutastic!

    7:11
    Sam: 
    Hi George, the HH4 image will be displayed in place of the HH3 in the next firmware release
    7:12
    Dave: 
    Thanks again DS - you shouldn't find that, but this can depend on a lot of different factors in the home. I've found mine to be a bit better actually! But it should be pretty much the same for most customers.

    Is it possible for BT to allow us to move the BTWifi SSID's to another channel, leaving our own SSID on a less congested channel?
    7:12
    Dave: 
    Hi imjolly, sorry for the delay, Emma asked me to reply on her behalf. We have made the stats in the Hub manager simpler for customers to understand, we were reacting to feedback that it was too general for the wide range of customers and tech understandings.

    Did you know the hub offers Easy Wireless?
    Connect wirelessly by selecting your BT Home Hub connection on any compatible device and just push a button on the Hub and you're connected. It's that simple. No passwords needed.

    Sam: 
    Hi DS, moving BT Wifi SSID's to another channel is not possible on the HH4. However, we are looking closely at the wi-fi SSID's the hub broadcasts to see whether we can improve this experience.
    7:15
    Dave: 
    Hi James, 5GHz maximum data transfer rate of 300Mb/s; this will tend to translate as an optimal actual speeds of up to 100 Mb/s - depending on lots of factors in your home

    Sam: 
    Hi Josh, we are aware of this issue. This is a problem with the Xbox rather than the HH4 but something we are reviewing together.
    7:24
    Emma: 
    Hi the bennyboy, the main advantages of the hub 4 are the faster processor (3 x faster) and 5 GHz wifi. There is no interference with 5GHz so you get better performance and as the range isn't as wide you dont have to share the bandwidth with neighbours etc. the hub still has 2.4 GHz so you still have the range you have withhub 3 too!
    7:24
    Dave: 
    Hi Winston, I am afraid there's no simple answer as it really depends on what features are in use. But the Hub 4 meets the latest Broadband Equipment Energy Code of Conduct targets for energy consumption.

    7:30
    Dave: 
    Hi Mel - we've made a lot of changes for our existing customers since the launch of the Hub 3 a couple of years ago. Our customer offer for the Hub 4 only £35 - a really big discount compared to the full price of £109! We've also created a range of recontracting deals that contain a Hub 4 for only the cost of delivery. If you're out of contract or in the last 3 months, you could take advantage of those offers as well. We really want all of our customers to be able to take advantage of these options!
    7:31
    Sean Donnelly: 
    Did you know the Hub 4 has a faster processor? Inside the BT Home Hub 4 router is our latest Broadband processor – the brains of your Hub. It allows you to pass information between connected devices quicker than ever. So if you are transferring files from one computer to another or watching a film streamed from another device, the BT Home Hub 4 won't slow you down.

  • ORA-06502 - Error when running "Ask The Expert 0.9"

    Hi ,
    I successfully installed "Ask the Expert" package with Apex 3.0 on Oracle 10g Database 10.2.0.1.0. No error ocurred during the import in my Apex environment.
    Besides that, i'm having problems when i tried to run the "Aks the Expert". It always shows the following message errors:

    OOPS !!
    I will repost the whole messaqge with the correct external URL's:
    In  general, the Trustsec design and deployment guides address the specific  support for the various features of the 'whole' Cisco TS (and other  security) solution frameworks.  And then a drill-down (usually the  proper links are embedded) to the specifc feature, and then that feature  on a given device.  TS 2.1 defines the use of ISE or ACS5 as the policy  server, and confiugration examples for the platforms will include and  refer to them.

  • Ask the Expert: Single-Site and Multisite FlexPod Infrastructure

    With Haseeb Niazi and Chris O'Brien 
    Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about Single-Site and Multisite FlexPod Infrastructure with experts Haseeb Niazi and Chris O'Brien.
    This is a continuation of the live webcast.
    FlexPod is a predesigned and prevalidated base data center configuration built on Cisco Unified Computing System, Cisco Nexus data center switches, NetApp FAS storage components, and a number of software infrastructure options supporting a range of IT initiatives. FlexPod is the result of deep technology collaboration between Cisco and NetApp, leading to the creation of an integrated, tested, and validated data center platform that has been thoroughly documented in a best practices design guide. In many cases, the availability of Cisco Validated Design guides has reduced the time to deployment of mission-critical applications by 30 percent.
    The FlexPod portfolio includes a number of validated design options that can be deployed in a single site to support both physical and virtual workloads or across metro sites for supporting high availability and disaster avoidance. This session covers various design options available to customers and partners, including the latest MetroCluster FlexPod design to support a VMware Metro Storage Cluster (vMSC) configuration.
    Haseeb Niazi is a technical marketing engineer in the Data Center Group specializing in security and data center technologies. His areas of expertise also include VPN and security, the Cisco Nexus product line, and FlexPod. Prior to joining the Data Center Group, he worked as a technical leader in the Solution Development Unit and as a solutions architect in Advanced Services. Haseeb holds a master of science degree in computer engineering from the University of Southern California. He’s CCIE certified (number 7848) and has 14 years of industry experience.   
    Chris O'Brien is a technical marketing manager with Cisco’s Computing Systems Product Group.  He is currently focused on developing infrastructure best practices and solutions that are designed, tested, and documented to facilitate and improve customer deployments. Previously, O'Brien was an application developer and has worked in the IT industry for more than 20 years.

    I would suggest you read this white paper which details the pros and cons of direct connect storage. 
    http://www.cisco.com/en/US/partner/prod/collateral/ps10265/ps10276/whitepaper_c11-702584.html   This paper captures all the major design points for Ethernet and FC  protocols.
    I would only add that in FlexPod we are trying to create a highly  available solution and "flexible" solution; Nexus switching helps us  deliver on both with vPC and unified ports.
    NPV equats  to end-host mode which allows the system to present all of the servers  as N ports to the external fabric.  In this mode, the vHBAs are pinned  to the egress interfaces of the fabric interconnects.  This pinning  removes the potential of loops in the SAN fabric.  Host based multipathing of the  vHBAs account for potential uplink failures.  The NPV mode (end-host  mode) simplifies the attachment of UCS into the SAN fabric and that is  why it is in NPV mode by default.
    So for your last question, I will have to put my  Product Manager hat on so bear with me.   First off there is no drawback  to enabling the NPIV feature (none that I am aware of) the Nexus 5000  platform simply offers you a choice to design and support multiple FC  initiators (N-Ports) per F-Port via NPIV.  This allows for the  integration of the FI end-host mode described above.  I  imagine being a  unfied access layer switch, the Nexus team enabled standard Fibre  Channel switching capability and features first.  The implementatin of  NPIV is a customer choice based on their specific access layer  requirements.

  • Ask the Expert: Scaling Data Center Networks with Cisco FabricPath

    With Hatim Badr and Iqbal Syed
    Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about the Cisco FabricPath with Cisco technical support experts Hatim Badr and Iqbal Syed. Cisco FabricPath is a Cisco NX-OS Software innovation combining the plug-and-play simplicity of Ethernet with the reliability and scalability of Layer 3 routing. Cisco FabricPath uses many of the best characteristics of traditional Layer 2 and Layer 3 technologies, combining them into a new control-plane and data-plane implementation that combines the immediately operational "plug-and-play" deployment model of a bridged spanning-tree environment with the stability, re-convergence characteristics, and ability to use multiple parallel paths typical of a Layer 3 routed environment. The result is a scalable, flexible, and highly available Ethernet fabric suitable for even the most demanding data center environments. Using FabricPath, you can build highly scalable Layer 2 multipath networks without the Spanning Tree Protocol. Such networks are particularly suitable for large virtualization deployments, private clouds, and high-performance computing (HPC) environments.
    This event will focus on technical support questions related to the benefits of Cisco FabricPath over STP or VPC based architectures, design options with FabricPath, migration to FabricPath from STP/VPC based networks and FabricPath design and implementation best practices.
    Hatim Badr is a Solutions Architect for Cisco Advanced Services in Toronto, where he supports Cisco customers across Canada as a specialist in Data Center architecture, design, and optimization projects. He has more than 12 years of experience in the networking industry. He holds CCIE (#14847) in Routing & Switching, CCDP and Cisco Data Center certifications.
    Iqbal Syed is a Technical Marketing Engineer for the Cisco Nexus 7000 Series of switches. He is responsible for product road-mapping and marketing the Nexus 7000 line of products with a focus on L2 technologies such as VPC & Cisco FabricPath and also helps customers with DC design and training. He also focuses on SP customers worldwide and helps promote N7K business within different SP segments.

    Hi Sarah,
    Thank you for your question.
    Spanning Tree Protocol is used to build a loop-free topology. Although Spanning Tree Protocol serves a critical function in these Layer 2 networks, it is also frequently the cause of a variety of problems, both operational and architectural.
    One important aspect of Spanning Tree Protocol behavior is its inability to use parallel forwarding paths. Spanning Tree Protocol forms a forwarding tree, rooted at a single device, along which all data-plane traffic must flow. The addition of parallel paths serves as a redundancy mechanism, but adding more than one such path has little benefit because Spanning Tree Protocol blocks any additional paths
    In addition, rooting the forwarding path at a single device results in suboptimal forwarding paths, as shown below, Although a direct connection may exist, it cannot be used because only one active forwarding path is allowed.
    Virtual PortChannel (vPC) technology partially mitigates the limitations of Spanning Tree Protocol. vPC allows a single Ethernet device to connect simultaneously to two discrete Cisco Nexus switches while treating these parallel connections as a single logical PortChannel interface. The result is active-active forwarding paths and the removal of Spanning Tree Protocol blocked links, delivering an effective way to use two parallel paths in the typical Layer 2 topologies used with Spanning Tree Protocol.
    vPC provides several benefits over a standard Spanning Tree Protocol such as elimination of blocker ports and both vPC switches can behave as active default gateway for first-hop redundancy protocols such as Hot Standby Router Protocol (HSRP): that is, traffic can be routed by either vPC peer switch.
    At the same time, however, many of the overall design constraints of a Spanning Tree Protocol network remain even when you deploy vPC such as
    1.     Although vPC provides active-active forwarding, only two active parallel paths are possible.
    2.     vPC offers no means by which VLANs can be extended, a critical limitation of traditional Spanning Tree Protocol designs.
    With Cisco FabricPath, you can create a flexible Ethernet fabric that eliminates many of the constraints of Spanning Tree Protocol. At the control plane, Cisco FabricPath uses a Shortest-Path First (SPF) routing protocol to determine reachability and selects the best path or paths to any given destination in the Cisco FabricPath domain. In addition, the Cisco FabricPath data plane introduces capabilities that help ensure that the network remains stable, and it provides scalable, hardware-based learning and forwarding capabilities not bound by software or CPU capacity.
    Benefits of deploying an Ethernet fabric based on Cisco FabricPath include:
    • Simplicity, reducing operating expenses
    – Cisco FabricPath is extremely simple to configure. In fact, the only necessary configuration consists of distinguishing the core ports, which link the switches, from the edge ports, where end devices are attached. There is no need to tune any parameter to get an optimal configuration, and switch addresses are assigned automatically.
    – A single control protocol is used for unicast forwarding, multicast forwarding, and VLAN pruning. The Cisco FabricPath solution requires less combined configuration than an equivalent Spanning Tree Protocol-based network, further reducing the overall management cost.
    – A device that does not support Cisco FabricPath can be attached redundantly to two separate Cisco FabricPath bridges with enhanced virtual PortChannel (vPC+) technology, providing an easy migration path. Just like vPC, vPC+ relies on PortChannel technology to provide multipathing and redundancy without resorting to Spanning Tree Protocol.
    Scalability based on proven technology
    – Cisco FabricPath uses a control protocol built on top of the powerful Intermediate System-to-Intermediate System (IS-IS) routing protocol, an industry standard that provides fast convergence and that has been proven to scale up to the largest service provider environments. Nevertheless, no specific knowledge of IS-IS is required in order to operate a Cisco FabricPath network.
    – Loop prevention and mitigation is available in the data plane, helping ensure safe forwarding that cannot be matched by any transparent bridging technology. The Cisco FabricPath frames include a time-to-live (TTL) field similar to the one used in IP, and a Reverse Path Forwarding (RPF) check is also applied.
    • Efficiency and high performance
    – Because equal-cost multipath (ECMP) can be used the data plane, the network can use all the links available between any two devices. The first-generation hardware supporting Cisco FabricPath can perform 16-way ECMP, which, when combined with 16-port 10-Gbps port channels, represents a potential bandwidth of 2.56 terabits per second (Tbps) between switches.
    – Frames are forwarded along the shortest path to their destination, reducing the latency of the exchanges between end stations compared to a spanning tree-based solution.
        – MAC addresses are learned selectively at the edge, allowing to scale the network beyond the limits of the MAC addr

  • Ask the Expert: One Management with Prime Infrastructure 1.2

    With Tejas Shah
    Welcome to the Cisco Support Community Ask the Expert conversation.

    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
    Markus

    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
    Amit Singh

    you can load you IOS from the tftpd32 , first donload tftpd32 from google its free, run it but make it sure that you have you IOS image bin file in you PC, then , follow these steps ,
    STEP 1.
                    Store the IOS image on the computer in any drive with its original name .
    STEP2.
               Connect the Switch to the Computer through straight cable.
    STEP 3.
                 Come to the Switch , come in the enable or privilege mode by entering   enable
                 Then come to the configuration mode , type  config terminal push enter
               Now type interface fast Ethernet or giga Ethernet port what ever the port is connected to the PC , example interface fast Ethernet 0/1 then push enter
    Now give ip address, like
    Ip address 1.1.1.1 255.0.0.0   enter
    No shut   enter
    STEP 3 .
                     Come to the PC GO TO THE NETWORk CARD and give the ip address 1.1.1.2 subnet mask 255.0.0.0 gateway 1.1.1.0 nothing else.
    STEP 4.
                 Now download    tftpd32  you can get it on google download it  AND RUN IT . AFTER THAT OPEN THE TFTP WHICH WILL BE ON DESKTOP , DOUBLE CLICK IT AND COME TO current directory and brows the IOS IMAGE FILE where you save that and select that it will then comes to the current directory , now below current directory you will see server interface , in front of that you will have to click show dir and see that the IOS file can be seen .
    STEP 5. COME TO THE SWITCH AGAIN , GO in enable mode.
    Type this.
                       Copy tftp flash. Push enter
                     It will ask you the name and address of remote host ?
    Give the IP ADDRESS of the system , 1.1.1.2 and push enter .
    Now it will ask you about the source file name ?
    Copy the file name from pc where the IOS IMAGE which is saved on the PC and past on the switch and type.bin in the end and push enter.
    Now the SWITCH will ask you about the destination file name , you can create your own name or use the same default name that is saved on the PC which you copy past on switch , after entering the name push enter. NOW WAIT FOR 10 MINUTES IF IT WILL ASK YOU SOMETHING PUSH ENTER AND WAIT FOR THE IMAGE TO UPLOAD.
    AFTER THAT COME TO THE enable mode and type wr  and the type reload and wait for the reboot process, in case you are using same destination file name as kept on the pc otherwise. Look below
    If you have create your own choice name then,
    Come to configuration mode , by typing config terminal push enter.

    we have "XR4U" stations coming available soon when XR 511 comes alive. The plan is for a downloadable play image like that. In the interim we have 2 demo systems available, and they can be booked via your account manager representative.
    How will MOD160 perform with multiple 9000NVS?
    very well. the mod 160 has 4 NPU's, 2 per bay. So if you have a 4x10 MPA to serve a satellite, you effectively have a single NPU per 20 1Gigs from the satellite. The pps performance will be stellar. However it might be price technically more ideal to connect satellite with a 36x10. Since the MOD-x has native MPA's with 1G also.
         2. Is there a shortcut for a Bundle-EthernetX interface, such as port-channel interface (poX), in Cisco IOS® ?.
    usability enhancement is there, we are trying to push this into a new reasonable release. follow CSCuh04526
         3. What  is the revolutions per minute (RPM) on these hard disk drives (HDDs)  compared to the solid state drives (SDDs)? Will the spinning drives be  slow?
    depends on the type we had avaialble at time of production, you will see different sizes and disks on the RSP2. the rpm of the HD is not so much an issue as much as the buffered writing we used to do in XR. This is fixed up with XR43 where the disk writing performance is much better. the HD/SDD is used for logging storage only (and maybe your pictures) but other then that we're not that concerned with write perf of the HD.

    You are correct, between the higher numbers of users with multiple devices the bandwidth requirements keep increasing.
    The limitation of three non-overlapping channels in the 2.4 GHz space is driving more customers to 5 GHz, it is important to have both bands when high density deployments are needed.  While many older devices only support 2.4 GHz, we are now seeing far more devices with 5 GHz as well.
    The recomendation of 20-25 clients and 8 voice calls on a given 2.4 GHz channel is still a good "rule of thumb" with actual customer data requirements driving those numbers higher or lower. You are right when you say "throwing Access Points" at the problem can degrade the wireless quality as co-channel interference and overall noise floor can rise with multiple Access Points that can all hear each other.
    A better approach to the problem is to throw more spectrum at this issue (using 5 GHz channels) and elements of 802.11n (20 MHz) bandwidth on 2.4 GHz.
    What we have been doing in high density deployments is to try to minimize the propagation of a cell and focus it in a given direction.  This can be done by
    1. Managing the RF power of the radios (Access Points) and in some cases the client's power (using elements of CCX).
    2. Using the right antennas to shape both Tx and Rx cell size to help isolate, we have recently introduced a new high gain antenna for stadiums that does this well.
    3. Limit supported rates, obviously the higher the data rate the less sensitive the receiver is and the smaller the cell size becomes.
    4. Enable 5 GHz (that adds far more channels for data throughput)
    5. Limit the number of SSIDs in use as each requires a separate beacon (adding to RF utilization)
    6. Co-locating access points with non-overlapping channels
    There are some challenges, for example; many dual -band clients prefer to connect to 2.4 GHz, and 2.4 GHz is more likely to be busier and subject to interference, so we also enable Cisco "Band-Select" which basically "nudges" those clients off 2.4 GHz and pushes them to 5 GHz so as to free up the 2.4 GHz band when we can determine the client has 5 GHz capability.
    So how is this done? well, we do this by listening to the clients and if we detect that the client is sending out probe requests on both bands we know the client can use 5 GHz so we essentially make the 5 GHz band "appear more attractive" to that client.
    Note: Client load balancing and Band select are features in the Cisco Unified controller menu.
    Also enabling client link (intelligent beam forming) helps direct the signal directly at the client and reduces same channel interference.

    Hi Nigel,
    Please take a look at the "WAN Requirements" section from the following Flex7500 deployment guide:
    http://www.cisco.com/en/US/products/ps11635/products_tech_note09186a0080b7f141.shtml
    It is highly recommended that the minimum bandwidth restriction remains 128 kbps with the round trip latency no greater than 300 ms for data deployments and 100 ms for data + voice deployments. The maximum transmission unit (MTU) must be at least 500 bytes.

    Hi Expert,
                     Before all, thank you for your great advice and helps. I've decided to implement a few of them. However, during preliminary test , i run into some issues. Hopefully, you will be able to help one last time.
    During my test, I implemented a few SSID wich worked fine in my lab with WEP encryption. And i decided to change the encryption, some of the SSID did work with wpa2. However, two remains my attention, the guess SSID which uses wpa with tkip and one of the test SSID. The guess SSID worked fine untill I decided to reload the AP. When the AP came back it could not grabs an ip, but sho commands shows that it is associate with the AP. See below. I am 100% certain that the config is correct as it was working fine before the reload.
    a) Show commands

    Can the radio interface get mess by the reload? How can I verify theradio? Debug did not show Client asking for IP...
    3. My last question, my ACLs to limit guess access. Should i implement them in my firewall or in my distribution router? The distribution router has a sub_interface for each SSID. Would it be better  to block traffic right from the distribution router rather let unecessary traffic flow to the network?
    Thanks a lot for great advice and guidance,
