Monitoring CoS Value Aliases

To display information about the CoS value aliases that the system is currently using to represent DSCP, DSCP IPv6, MPLS EXP, and IPv4 precedence bits, select Monitor > Class of Service > CoS Value Aliases or enter the following CLI command:

show class-of-service code-point-aliases

After you make changes to the configuration in this window, you must commit the changes immediately for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes (J-Web Procedure) for details about all commit options.

Table 55 summarizes key output fields for CoS value aliases.
