Configuring Congestion Avoidance
Pre-configuration Tasks
After congestion avoidance is configured, the device discards excess packets based on the configured drop profile to adjust the network traffic and solve the network overload problem.
Before configuring congestion avoidance, complete the following tasks:
Configure priority mapping.
Configure priority re-marking based on traffic classifiers.
Configure congestion management.
Configuration Procedure
Queue-based and class-based congestion avoidance cannot be configured simultaneously.
The device search the drop profile for the DSCP priority mapping the EXP priority multiplied by eight and discards the MPLS packets based on the drop profile. For example, if the EXP priority of packets is 2, the device searches a drop profile for DSCP 16 and discards packets based on the drop profile.
