Hierarchy Level

Release Information

Statement introduced in Junos OS Release 7.4.

Support at the [edit dynamic-profiles ... single-rate] and [edit dynamic-profiles ... two-rate] hierarchy levels introduced in Junos OS Release 11.4.

Statement introduced in Junos OS Release 12.3R2 for EX Series switches.

Description

For a three-color policer, configure the way preclassified packets are metered. In color-aware mode, the local router can assign a higher packet loss priority, but cannot assign a lower packet loss priority.

For example, suppose an upstream router assigned medium-high packet loss priority to a packet because the packet exceeded the committed information rate on the upstream router interface.

  • If the local router applies color-aware policing to the packet, the router cannot change the packet loss priority to low, even if the packet conforms to the configured committed information route on the local router interface.
  • If the local router applies color-blind policing to the packet, the router can change the packet loss priority to low if the packet conforms to the configured committed information route on the local router interface.

Note: A color-aware policer cannot be applied to Layer 2 traffic.

Default

If you omit the color-aware statement, the default behavior is color-aware mode.
