Configuring PLP for Drop-Profile Maps

RED drop profiles take action on outgoing packets. When TCM is enabled, M320 and T Series routers support four drop-profile map PLP designations: low, medium-low, medium-high, and high.

To configure the PLP for the drop-profile map, include the schedulers statement at the [edit class-of-service] hierarchy level:

[edit class-of-service]schedulers {scheduler-name {drop-profile-map loss-priority (any | low | medium-low | medium-high | high)protocol any drop-profile profile-name;}}

When you configure TCM, the drop-profile map’s protocol type must be any.

The inputs for a drop-profile map are the loss priority and the protocol type. The output for a drop-profile map is the drop profile name. In other words, the map sets the drop profile for each packet with a specific PLP and protocol type exiting the interface.

For example, in the following configuration, the dp drop profile is assigned to all packets exiting the interface with a medium-low PLP and belonging to any protocol:

class-of-service {schedulers {af {drop-profile-map loss-priority medium-low protocol any drop-profile dp;}}}

To use this drop-profile map, you must configure the settings for the dp drop profile at the [edit class-of-service drop-profiles dp] hierarchy level. For more information, see RED Drop Profiles Overview.
