Traffic-Priority - 3Com 5500-EI PWR Reference Manual

The granularity of rate limit is 64 kbps. If the number you input is in the range N*64 to
(N+1)*64 (N is a natural number), it will be rounded off to (N+1)*64.
burst-bucket burst-bucket-size: Specifies the maximum burst traffic size (in KB) allowed.
The burst-bucket-size argument ranges from 4 to 512 and defaults to 512. Note that it must
be an integer power of 2.
exceed action: Specifies the action to be taken when the traffic rate exceeds the threshold.
The action argument can be:
drop: Drops the packets.
remark-dscp value: Sets a new DSCP value for the packets and then forwards the
packets.
Description
Use the traffic-limit command to enable traffic policing and set the related settings.
Use the undo traffic-limit command to disable traffic policing for packets matching
specific ACL rules.
Related commands: display qos-interface traffic-limit.
Examples
# Configure traffic policing for inbound packets sourced from VLAN 200 on Ethernet 1/0/1,
setting the target packet rate to 128 kbps, burst bucket size to 64 KB, and configuring to
drop the packets exceeding the rate limit.
