If you configure ingress or egress traffic-shaping overhead values for an interface, the
traffic manager cannot apply these values to any rate-limiting also applied to the interface.
To enable the router to account for the additional Ethernet frame length when policing
actions are being determined, you must configure the ingress or egress overhead values
for policers separately.
NOTE: When a policer overhead value is changed, the PIC or DPC goes offline
and then comes back online.
For Gigabit Ethernet Intelligent Queuing 2 (IQ2) and Enhanced IQ2 (IQ2E) PICs or
interfaces on Dense Port Concentrators (DPCs) in MX Series routers, you can control the
rate of traffic that passes through all interfaces on the PIC or DPC by configuring a policer
overhead. You can configure a policer ingress overhead and a policer egress overhead,
each with values from 0 through 255 bytes. The policer overhead values are added to
the length of the final Ethernet frame when determining ingress and egress policer actions.
