Policy Framework Configuration Guide - Juniper Networks

Chapter 11: Policer Configuration
The configurable actions are to discard the packet, change the loss priority, or change
the forwarding class.
3. Configure the premium policer.
[edit firewall policer policer1]
user@host# set premium if-exceeding bandwidth-limit 200m burst-size-limit 50k
user@host# set premium then forwarding-class af
For the premium policer, the only configurable action is to discard the packet.
4. Apply the policer to an interface.
[edit interfaces so-1/0/0 unit 0]
user@host# set layer2–policer input-hierarchical-policer policer1
5. Verify that the policer is working as expected.
user@host> show interfaces so-0/0/0.0 detail
user@host> show interfaces so-0/0/0.0 statistics detail
user@host> show policer

Configuring Policers
To configure policers, you include statements at the [edit firewall] hierarchy level of the
configuration:
[edit firewall]
policer policer-name {
filter-specific;
if-exceeding {
bandwidth-limit bps;
bandwidth-percent number;
burst-size-limit bytes;
}
logical-bandwidth-policer;
logical-interface-policer;
physical-interface-policer;
then {
policer-action;
}
}
hierarchical-policer hierarchical-policer-name {
aggregate {
if-exceeding {
bandwidth-limit bps;
burst-size-limit bytes;
}
then {
policer-action;
}
