[edit firewall policer LB-policer]
user@host# set logical-bandwidth-policer
This applies the rate-limiting to logical interfaces.
Configure the policer traffic limits and actions.

[edit firewall policer LB-policer]
user@host# set if-exceeding bandwidth-percent
user@host# set if-exceeding burst-size-limit
user@host# set then discard
Confirm the configuration of the policer by entering the
command. If the command output does not display the intended configuration, repeat
the instructions in this procedure to correct the configuration.
