Rate Limiting on 4500's Gig port

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

Re: Rate Limiting on 4500's Gig port

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.

Re: Rate Limiting on 4500's Gig port

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.

Re: Rate Limiting on 4500's Gig port

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.
