Rate limit 2960 Port to 1 MB

[imranraheel]

Please let me know how to rate limit the 2960 switch port to 1 MB.

I have made the specified chnages , how ever still it is reaching more tha 1 MB

Hard coded the bandwidth of port to 10 MB and have applied the specified command

srr-queue bandwidth limit 10

Still the computer on that port is reaching more than 1 MB

In which direction does the traffic surpass 1Mb/s?

The srr queue commands are for egress only. If you want to limit ingress as well then you need to add a service policy to the interface that polices traffic to the required rate.

Also the srr-queue bandwidth limit command is not exact so you may see traffic egress the port above the set rate.

1) Enabled QoS globally...

2960(config)#mls qos

2) Configure an ACL to define the matched traffic...

2960(config)#access-list 111 permit ip any any

3) Configure a class map for the matched traffic...

2960(config)#class-map traffic

2960(config-cmap)#match access 111

4) Configure a policy-map to define action...

2960(config)#policy-map Control

2960(config-pmap)#class traffic

2960(config-pmap-c)#police 10000000 8000 exceed-action drop

5) Attached the policy-map to the interface.

a) Example

-In this case, I'll attach the policy map to port_1....

2960(config)#int fa0/1

2960(config-if)#service-policy input Control

>>>>>> This will rate-limit traffic coming from the PC

Tried this solution on my WS-C2960-8TC-S V.12.2 but class-map and policy-map command does not seem to work.

Is there any solution for that?
