Assigning the Default Frame Relay Loss Priority Map to an Interface
For SRX210, SRX240, and SRX650 firewall 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:
loss-priority low code-point 0; loss-priority high code-point 1;
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:
[edit class-of-service interfaces interface-name unit logical-unit-number loss-priority-maps] frame-relay-de default;
