Assigning the Default Frame Relay Discard Eligibility Loss Priority Map to an Interface
For interfaces with the Frame Relay encapsulation
on M120 routers, M320 routers with Enhanced III FPC, M7i and M10i
routers with Enhanced Compact Forwarding Engine Board, and MX Series
routers, you can set the loss priority of Frame Relay traffic based
on the discard eligibility (DE) bit. For each incoming frame with
the DE bit containing the class-of-service (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;
The default map sets the loss priority to low for each incoming
frame with the DE bit containing the CoS value 0. The map
sets the loss priority to high for each incoming frame with the DE
bit containing the CoS value 1.
