Cisco catalyst 2960 switch - port bandwidth limit

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

Cisco catalyst 2960 switch - port bandwidth limit

by izigic In reply to see link below

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

cisco commands

by CG IT In reply to Cisco catalyst 2960 switc ...

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 switc ...

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.

Cisco catalist 2960 switch port bandwidth limit

by izigic In reply to Check out this article fo ...

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..

Hi all

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.
