I am looking for step-by-step configuration on how to enable rate-limit and traffic shaping on Cisco 6513 vlan interfaces. I am not able to find this particular document on CCO.
Solved! Go to Solution.

Hi Abbas,
As long as you have a seperate Vlan's then it would be possible to allocate bandwidth under the vlan's
See the below two individual examples may help in your scenario.
STEP-1:
Apply rate-limit on each L3 vlan interface in your 2851
Example (for 1024kbits for vlan 2):
Router# conf t
Router(config)# int vlan 2
Router(config-if)#rate-limit input 1000000 187500 375000 conform-action transmit exceed-action drop
Router(config-if)#rate-limit output 1000000 187500 375000 conform-action transmit exceed-action drop
STEP-2:
Policy a specific VLAN number on VLAN interface.
class-map vlan5
match vlan 5
match class-map class-default
policy-map vlan5-limit
class vlan5
police 2000000 250000 exceed-action drop
int vlan5
service-policy input vlan5-limit
After you apply this configuration, the traffic with VLAN 5 coming from any will be policed at 2Mbps.
Hope this will help you.

Thanks Naidu! Two questions, The sample config you sent is related to 2851 Router. Will it work with Internal LAN traffic by enabling on Cisco 6513 Switches.
The rate-limit and policing will simply drop the packet if it exceeds the configured bandwidth. Wouldn't traffic shaping be a better option where traffic will be buffered and prirotized instead of drop. If traffic shaping will be a better option then can you post the sample config for traffic shaping on Cisco 6513 swtiches
