Assigning the Default Frame Relay Loss Priority Map to an Interface

For SRX210, SRX240, and SRX650 device interfaces with Frame Relay encapsulation, you can set the loss priority of Frame Relay traffic based on the discard eligibility (DE) bit. (Platform support depends on the Junos OS release in your installation.) For each incoming frame with the DE bit containing the CoS value 0 or 1, you can configure a Frame Relay loss priority value of low, medium-low, medium-high, or high.

The default Frame Relay loss priority map contains the following settings:

This default map sets the loss priority to low for each incoming frame with the DE bit containing the 0 CoS value. The map sets the loss priority to high for each incoming frame with the DE bit containing the 1 CoS value.

To assign the default map to an interface, include the frame-relay-de default statement at the [edit class-of-service interfaces interface-name unit logical-unit-number loss-priority-maps] hierarchy level:
