On one interface, you can configure the rate limit or rate police command for a VLAN or you can
configure the rate limit or the rate police command for the interface. For each physical interface, you
can configure six rate limit commands specifying different VLANS.
If you receive the error message:
%Error: Specified VLANs overlap with existing config.
after configuring VLANs in the rate police command, check to see if the same VLANs are used in rate
limit command on other interfaces. To clear the problem, remove the rate limit configuration(s), and
re-configure the rate police command. After the rate police command is configured, return to the other
interfaces and re-apply the rate limit configuration.
