User Guidelines
Traffic policing in a policy map takes precedence over VLAN rate limiting. If a
packet is subject to traffic policing in a policy map and is associated with a VLAN
that is rate limited, the packet is counted only in the traffic policing of the policy
map.
This command does not work in Layer 3 mode. It does not work in conjunction with
IP Source Guard.
Example
The following example limits the rate on VLAN 11 to 150000 kbps or the normal
burst size to 9600 bytes.
