Verifying Link Services CoS

Purpose

Verify CoS configurations on the link services interface.

Action

From the CLI, enter the following commands:

show class-of-service interface interface-name
show class-of-service classifier name classifier-name
show class-of-service scheduler-map scheduler-map-name

The sample output provided in this section is based on the configurations provided in Configuring MLPPP Bundles and LFI on Serial Links.

Meaning

These output examples show a summary of configured CoS components. Verify the following information:

Logical Interface—Name of the multilink bundle and the CoS components applied to the bundle. The sample output shows that the multilink bundle is lsq-0/0/0.0, and the CoS scheduler-map s_map is applied to it.
Classifier—Code points, forwarding classes, and loss priorities assigned to the classifier. The sample output shows that a default classifier, ipprec-compatibility, was applied to the lsq-0/0/0 interface and the classifier classify_input was applied to the ge-0/0/1 interface.
Scheduler—Transmit rate, buffer size, priority, and loss priority assigned to each scheduler. The sample output displays the data, voice, and network control schedulers with all the configured values.
