Rate Limiting on 4500's Gig port

[jbhatia_9]

I am trying to enable rate-limiting on a Gig Port(GBIC) on the 4500's.

I have a customer connected via fiber but I only have to provide him with 1 vlan and 10MB of bandwidth.

What is the best way to do this?

Thanks,

Jeet

you can set the gig port to limit the interface speed to 10MB.

S(config)# interface g1/1

S(config-interface)# speed auto 10

this will setup auto-negotiation to only link at 10MB.

or just set the port to 10 half statically if it is capable.

This is gig port with a GBIC and it only does 1000. You cannot change the speed to 10 or 100 on these ports.

I was hinting more towards some kind of service policies. Its not totally clear to me how it can be done at L2, any help will be appreciated.

Hi,

As per your query, I think you need layer Rate limiting. Config is different for layer2 and layer3. Please try the commands below, i think this will work, if not get back or refer the link given below.

Please refer more about COS and DSCP to know more about layer2 QOS.

Switch# configure terminal

Switch(config)# interface gigabitethernet 1/1

Switch(config-if)# qos trust cos

Switch(config-if)# qos cos5

Switch(config)# qos map cos 5 to tx-queue 2

Switch(config)# interface gigabitethernet 1/1

Switch(config-if)# tx-queue 2

Switch(config-if-tx-queue)#bandwidth 10000000

Switch(config-if-tx-queue)# shape 10000000

For more details please refer the links below.
