Release Information

Statement introduced before Junos OS Release 7.4.

Description

For Gigabit Ethernet IQ and Gigabit Ethernet PICs with SFPs (except the 10-port Gigabit Ethernet PIC and the built-in Gigabit Ethernet port on the M7i router), configure MAC policing.

On MX Series routers with Gigabit Ethernet or Fast Ethernet PICs, the following considerations apply:

Interface counters do not count the 7-byte preamble and 1-byte frame delimiter in Ethernet frames.
In MAC statistics, the frame size includes MAC header and CRC before any VLAN rewrite/imposition rules are applied.
In traffic statistics, the frame size encompasses the L2 header without CRC after any VLAN rewrite/imposition rule.

Options

input cos-policer-name—Name of one policer to specify the premium bandwidth and aggregate bandwidth.

output cos-policer-name—Name of one policer to specify the premium bandwidth and aggregate bandwidth.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.
