    Cisco catalyst 2960 switch – port bandwidth limit

    Locked

    by izigic ·

    Dear all,

    I want to set/limit bandwidth in a Cisco catalyst 2960 switch. Cisco IOS version is 12.2(53)SE and model is 2960-48TT – L
    My objective is, for example, I want to limit bandwidth for fa0/1 to 256kbps, for fa0/2 512kbps.

    Please help.

    Thanks and regards
    Igor

        Hi CG IT,
        Thanks for your reply. If it were easy as google the answer, I would not have asked a question here.
        My objective is to limit b/w less than 1Mbps (ex – 512kbps or 256 kbps).
        It would be great if you help me out.
        thx

          well to determine what speed the port will operate at use the following commands.

          router#config t

          router#(config)int fa?/? (specify port number)

          Router#(config-int)speed ? (the question mark after speed will list all the speeds that the port will operate at. (10/100/1000 or auto).

          the ethernet switch operates on ethernet standards. 10mbps, 100mbps and 1000mbps or auto which the port negotiates the speed.

          bandwidth throttling vs port speed

          by churdoo ·

          In reply to Cisco catalyst 2960 switch – port bandwidth limit

          I believe the OP is asking about bandwidth throttling, not port speed. I think that’s a layer 3 function, so I doubt you can do that on the 2960 nor any 2xxx series device.

          Someone correct me if I’m wrong.

          netman has a really good solution QoS.

        Cisco catalist 2960 switch port bandwidth limit

        Hi netman

        Catalyst 2960 is Layer2 switch and any Layer3 technique won’t work on it. However this switch is capable of doing QoS and this workaround was very helpful
        Solution is not perfect but it is working

        This is what I did on the switch

        mls qos
        !
        interface fa0/1
        bandwidth 1000 ! Specify interface bandwidth for QoS purpose
        srr-queue bandwidth limit 4 ! limit maximum bandwidth on the port to
        4% of the port bandwidth, approximately to 250K

        Netman… thanks for pointing me to the right direction.. 😉

      This issue was discussed earlier. The “srr-queue bandwidth limit” minimum percentage allowed only 10! I think you first need to set the port speed to 10mps then use the limit percent to 40 to get the 4mps. Use ingress & egress service policies to get the desired speed.
