Aggregating Policiers
After a packet is classified, the policing process begins. A policier specifies the bandwidth limit for incoming traffic
on the classified flow and actions are defined for packets that exceed the limits. These actions include forwarding
packets, dropping packets, or remarking packets with a new DSCP value. The device supports per flow and
aggregate policiers.
Aggregate policers enforce limits on a group of flows. An aggregate policer cannot be deleted if it is being used in
a policy map. The Aggregated Policier Page contains information for defining the bandwidth limits and define
actions to take on packets that do not meet the requirements. To configure Aggregated Policiers:
1. Click Advance Setup > Quality of Service > Policy Properties >Aggregated Policier. The Aggregated
Policier Page opens:

– Drop — Packets exceeding the limits are dropped.
– Remark DSCP — Packets exceeding the limits are forwarded with a flagged/remarked DSCP value.
