Re: Cisco 3750 egress rate-limit

Hi, I've setup a 7206 NPE-G1 with one of its gigE interface connected to a Catalyst WS-C3750-24TS with each port assigned to specific VLAN interface. The VLAN are configured on the 3750, each with its own subnet (The first IP is the gateway for each switchport customer).I need to rate limit the traffic on each port to 2Mbps ingress (in) and egress (out). I've tried using the rate-limit command on each VLAN interface but the MRTG shows that its not working as traffic goes more that specified.

rate-limit input 2048000 1500 2000 conform-action transmit exceed-action drop rate-limit output 2048000 1500 2000 conform-action transmit exceed-action drop

I've also tried policing but when its applied to the specific interface (physical or VLAN) using "service-policy output xxxx", i get the error

"Warning: Assigning a policy map to the output side of an interface not supported "

%QOSMGR-4-CLASS_NOT_SUPPORTED: Classification is not supported in classmap DSCPOLICE

I've tried looking for solutions but at the moment there is not much available even on the cisco web site. I really need to get this up and running as soon as possible. Hope to get some help in resolving this issue. Thanks
