3com 8807 Reference Guide

■

When you configure traffic policing for a port group, all the ports in the port 
group occupy the same bandwidth, that is, the configured traffic parameter is 
shared by all the ports.

cir: Committed information rate in Kbps.

cbs: Committed burst size in bytes.

ebs: Excess burst size in bytes.

pir: Peak information rate in Kbps.

conform: Optional parameter used to set the action to be taken when the traffic 
does not exceed the set value.

remark-cos: Sets new 802.1p priority value for the packet according to its 
conform level and local precedence.

remark-drop-priority: Sets drop precedence value for the packet according to its 
conform level.

remark-policed-service: Sets new service parameters for the packet according to 
its conform level and DSCP value.

exceed: Optional parameter to set action for the case when traffic threshold is 
exceeded.

■

forward: Forwards the packet.

■

drop: Drops the packet.

traffic-index index: Traffic index.

slot slotid: Slot number of a service processor card.

Use the traffic-limit command to activate an ACL and set traffic limitation to take 
different actions for the packets within and beyond the preset traffic threshold.

Use the undo traffic-limit command to remove traffic limitation setting.

This command is only applicable to the packets which match the permitted rules in 
the ACL.

It is required that CIR is less than or equal to PIR and CBS is less than or equal to 
EBS. You are recommended to configure CBS and EBS to numbers that are 100 to 
150 times of CIR.

For the same traffic, you cannot select both the remark-cos and 
remark-policed-service keywords, or both the remark-drop-priority and 
remark-policed-service keywords.

Before selecting the remark-policed-service keyword, you must make sure you 
have configured the DSCP + Conform-Level -> Service parameter mapping table. 
Before selecting the remark-cos keyword, you must ensure you have configured
