Distrabuted Access Switch Design

HI,
I have been asked to do some research on a network design that eliminate the need for IDF's or at least the most of them. So we are going to add a new location which will have 3000 drops and instead of running all those drops back to a IDF or MDF, the estimated cost for each drop would be around 400. The plan is to setup switches on the ceiling or somewhere closer the actual drops which would also be more cost efficient. Since you won't need to run the cabling long distance and have to terminate them. Does anyone have any advice or have tried something like this before.

Isn't that how you would do it normally?  You would have longer cable runs and potentially bigger IDFs by putting the switches in a closet, but 99% of the time your IDF is going to be fiber uplinked to the core.  
The design that you are suggesting really only saves copper cable length.  But I don't know how much of a cost savings that is going to be because you are now running 2 fibers from several more IDF switches which means more fiber and more ports used on the core.  There's an expense with that.
If you stick with a bigger IDF design then you can use stackable switches and only need 2 uplinks from each IDF closet.

  • SAN design : core edge and dual-homing access switch

    Hello all.
    It may sound as a dumb question (from a LAN guy) but when designing a core/edge or edge/ecore/edge design, why do we connect access switches to both core switches ? Doesn't it break the isolation of a dual fabric backbone ?
    If an access switch fails the fault (bug or anything else) will propagate to both core switches ? Am I wrong ?
    Example :
    http://www.cisco.com/en/US/prod/collateral/modules/ps5991/prod_white_paper0900aecd8044c807_ps5990_Products_White_Paper.html
    or from netrworkers sessions in 2006

    Answer also from LAN guy,
    Most likely this design diagram is due to assumption that there is no use of VSANs and SAN Multipathing drivers in host.
    Following is excerpt from same like yo posted.
    "SAN designs should always use two isolated fabrics  for high availability, with both hosts and storage connecting to both  fabrics. Multipathing software should be deployed on the hosts to manage  connectivity between the host and storage so that I/O uses both paths,  and there is non-disruptive failover between fabrics in the event of a  problem in one fabric. Fabric isolation can be achieved using either  VSANs, or dual physical switches. Both provide separation of fabric  services, although it could be argued that multiple physical fabrics  provide increased physical protection (e.g. protection against a  sprinkler head failing above a switch) and protection against equipment  failure.

  • Design for redundancy of access switch

    hello all,
    I have the following design for a site:
    Provider delivers channel with HSRP redundant routers, but access level in not redundant and represented by one switch.
    Am I correct that there is no way no provide redundancy on access level only with access switches or there are any design proposals?!

    As Reza describes, many hosts only have a single connection to network, so that single connection is always a possible point of failure.  But there's a couple of things you can do to minimize the impact of a network infrastructure device failure.
    When working with small appliance type switches, you might have multiple smaller switches rather than one large switch.  For example, instead of having one 48 port switch, you might have two 24 ports switches, or six 8 port switches, etc..  If a switch fails, not all hosts lose connectivity.
    You can also have additional ports, ideally enough to handle lost of any one unit of hardware,  So, for example, if you have seven 8 port switches, when you only need 48 ports, if a switch fails, you only lose 1/7 of your hosts until they can be repatched into available ports on the other switches.
    If some of your hosts have multiple NICs, then there are various method to use the two NICs to avoid a single network unit failure from dropping the host.  Usually only shared servers merit that level of redundancy.

  • Spanning vlans across access switches in distribution block.... please help

    Hi All
    Can someone please explain why Cisco states that in a Campus Hierarchical modle if Vlans are spanned across Access switches in a distribution block, then the Distrubution to distribution link should be Layer 2. Is this really necesary or just a recommendation, and if so why? Can't this link be a L3 link when spanning vlans across Access switches in distribution block, as I understand the benefit of having a L3 distribution to distribution link so that SPT is avoided.
    Please help

    Hello,
    The cisco recommended design is L3 links, but these is only possible if you have no vlans you need to span over the hole network.
    It depends on your topology or what you want achieve.
    If you need for one or more vlan's spanned the LAN, you need to use a layer 2 connection between all switches and between distribution too.
    In my company we have for example a few vlans for restricted areas, like device management or else, so we can't use L3 Links in the distribution area because these vlan's are terminated at the firewall. I think these is good thing.
    I would recommend you if you don't have to span one or more vlan's across the network to use L3 Links, specially in the case of redundancy way's. So you need no spanning-tree, but need to use other protocols like GLBP or else. The works faster and are not so confusing (for some people) as STP.
    best regards,
    Sebastian

  • Server farm switch design

    Hi
    Pls see attachment
    Can i have the topology mentioned in the Attachment special from the access switch to the Core?is it good design ? what is your recommendation?
    thanks

    I can recommend only V-shaped design as it provides great redundancy in case of almost any failures. As you said, if etherchannel fails b/w two access switches, then the Acess-switch-1 and UP to Serverfarmswitch-1 is completely isolated from the other. I believe, even for dual attached servers also, V-shape design suits best.

  • [solved] DHCP snooping in environment with core and access switches

    Hello,
    I'd like to know what steps are needed to configure DHCP snooping in my environment:
    1) two core switches Catalyst 6500 (VSS): VLAN defined here, DHCP server connected here
    2) access switches Catalyst 3750: clients connected here
    Access switches are connected to core ones via trunk ports (fiber optics).
    How many snooping databases are required?  One for core and next for each stack?

    Hi Marian,
    If your network is properly designed and connected so that clients, including DHCP clients, are attached to the access layer switches, then the DHCP Snooping should be run only on access switches. Running DHCP Snooping on core switches is not going to increase the security because the DHCP communication has already been sanitized on the access layer.
    If you intend to save the DHCP Snooping database then each switch performing the DHCP Snooping needs to have its own database if you intend to use a persistent storage for it. However, you can always have the switch to save the database to its own FLASH, alleviating the need for a centralized networked storage.
    I am not sure if this answers your question so please feel welcome to ask further.
    Best regards,
    Peter

    Easwar

    Hi Easwar,
    What you see is STP working properly, and the port roles and states are exactly as they should be. Even on a redundant link between switches, exactly one port must be a Designated port in the Forwarding state. STP never blocks a redundant link between switches on both ends. First, it is not necessary to prevent loops: as long as your Sw1 has its port in the Blocking state, it will not be using that link to forward data. Second, if there was an unmanaged switch connected between Sw1 and Sw2 with some stations attached, and both Sw1 and Sw2 had their ports in the Blocking state, the stations connected to this unmanaged switch would be entirely cut off from the network.
    Is there any particular reason why you want the port to be blocking?
    Best regards,
    Peter

  • What are the major differences between a Access Switch and Aggregation Switch w.r.t Carrier Ethernet domain?

    In a Carrier Ethernet domain,Could someone please help me understand what's the basic difference between Access Switch and Aggregation Switch both in terms of s/w and h/w functionalities. MEF deals OAM,CFM, EVC provisioning only at the access edge switches. Do we need to repeat all these at the aggregation level? or  is it just used for routing purpose? Do we have a separate Fault Management at the aggregation level?

    created by TundraSteve in LiveCycle Designer - View the full discussion
    There is a terminology issue here.  From Acrobat Pro X you launch Designer
    not LiveCycle ES2.  LiveCycle is a server product.
    When you install Acrobat you have the option to install or not install
    Designer.  Look in the folder C:\Program Files (x86)\Adobe\Acrobat 10.0
    and check to see if there is a Designer 9.0 folder.  When in Acrobat you
    should be able to create a new form and it will prompt if you want to use
    Designer.  If all else fails you can always go into the Designer 9.0
    folder and launch FormDesigner.exe

  • Error While Accessing Universe Designer

    I am able to telnet my server ip with port 6400 and 8080.
    Thanks

    I think there is some problem because of firewalls.
    Could some one tell me what are the list of ports need to be opned for server client model.
    i asked network team to open the ports 6400 -6410 only.
    Do i need to open ports ??
    My BO server installation is default and CMS is on - 6400. and i haven't configured anything else.
    pls suggest the approach.

  • Timed Access Switching Off??

    My settings in Timed Access seem to hold for maybe a few days at a time, but then all of a sudden when I check it, the Timed Access tab reads Not Enabled.
    No one else can be turning it off as I am the only one that knows the password.
    Has anyone else experienced Timed Access switching itself off?...It is a useless feature if I can't rely on it to stop various devices from accessing my network at various times.

    I can't find the links now that I'm specifically looking for them, but recall reading posts from several users who have posted over in the Lion forum with the same issue.
    One user reported that after he reset the AirPort Extreme to factory default settings and then manually set it up again, that things worked fine.
    it's a hassle to have to enter in all the Timed Access data again, but might be worth a shot. If you decide to try this, be sure to change the default rule in Timed Access (which allows all devices access).
    It's best to set the default rule to "No Access" then enter in the specific MAC Addresses or AirPort IDs for devices. You've probably already done this in the past, but some users forget to change the "default" rule and then wonder why things don't work as expected.
    No guarantees that this will work, of course. Up to you if you want to try.

  • Small DC Switch Design

    Hello,
    I'm working on options for a small DC switch design.  This DC has 5
    virtual hosts with 10-20 guest vm's each.  Each server has two quad
    port gig nics with 6 of the 8 gig ports connected (3 for iSCSI and 3
    for data or management.  It also has two 3 node sans each with 2 gig
    ports per node, a host of other small servers including voice servers,
    management servers, asa firewall, and a few routers.  Total of 50-60
    ports as of right now.
    Connected to the DC is 7 other buildings each with there own 1 gig
    fiber connection serving about 3000 devices in total including
    desktops, laptops, ip phones, wireless ap's, building automation,
    alarm panels, etc....
    Right now in each of the 7 buildings has a 3560G as an aggregation
    switch connected back to the DC.  The DC also has a few 3560G's and
    3750G's for the sans and servers.  The system seems to work ok for the
    most part aside from micro bursts overwhelming the buffers on these
    switches and the etherchannel trunks between them dropping a minor
    amount of packets.  QOS is configured for the voice network and there
    are little to no complaints.
    What I would like to know (costs being the biggest factor) is what
    would be a better switch design for the current and future traffic in
    this network.  Some options I was thinking about are as follows:
    I would needs at least 96 ports.
    So option A is to go with a 4506-E bundle with 2 48 port line cards,
    sup 6l-e and a WS-X4712-SFP+E or something of the sorts.   And then
    upgrade to the enterprise services license and do all of the routing
    and switching for the DC on this one switch.  Means little redundancy
    and no failover.
    Option B was to go with the same 4506-E bundle, without the extra
    license and without the SFP line card and put in some sort of layer
    three aggregation switch, possibly an me3600x.
    Option C Is to go with the 4503-E, the SFP line card and the IP
    Enterprise services license.  And two top of rack switches, either
    2360's or 4948's.
    I would like to do some PBR on the aggregation switch, but I am unsure if the me3600x is capable of doing that.
    I have no experience in this matter so any other thoughts or
    suggestions would be appreciated.
    Thanks,
    Dan.

    If cost is the biggest factor, and the only notable issue now is occasional packet drops due to insufficient buffers, perhaps some buffer tuning would be something to consider.
    A really important question to answer is how important redundancy. At lower port densities (3 to 4 stack members), the switch stack is less expensive than a chassis that supports redundancy.  At very low port densities (2 to 3 stack members) the stack might be less expensive than even a non-redundant chassis.
    BTW, the 3750-E/X offers much more performance than the original 3750 series.  If offers wire-speed PPS and fabric per switch, twice the ring bandwidth and uses the ring, for unicast, much "smarter".
    Perhaps a dual WS-C3750X-12S or WS-C3750X-24S for your core with dual MEC fiber etherchannl links to your aggregation switches?  In the DC itself, you might also use 2960s to provide DC edge ports.  For growth, a dual 3750-X stack would support four 10 gig ports which could be used with 10 gig servers or 10 gig SAN or as a 10gig link to other DC switches, such as the 2960S (which support their own stacking technology).

  • Stop broadcasts on edge access switches to a port

    I have a telco person wanting to put the management port of their phone switch on to the network in one of our remote offices. They say that it will not handle broadcast very well and it will cause it to reset.
    So is there a way to limit the broadcast traffic to the port the phoneswitch is connected to. Or is there another way to accomplish this.
    using switches like edge access switches 3500XL, 2900XL, 3550 etc and or small routers like 1700 series.
    Thanks.
