Monitoring CoS Rewrite Rules
Purpose
Use the monitoring functionality to display information about CoS value rewrite rules, which are based on the forwarding class and loss priority.
Action
To monitor CoS rewrite rules in the CLI, enter the CLI command:
user@switch> show class-of-service rewrite-rule
To monitor a particular rewrite rule in the CLI, enter the CLI command:
user@switch> show class-of-service rewrite-rule name rewrite-rule-name
To monitor a particular type of rewrite rule (for example, DSCP, DSCP IPv6, IEEE-802.1, or MPLS EXP) in the CLI, enter the CLI command:
user@switch> show class-of-service rewrite-rule type rewrite-rule-type
Meaning
Table 1 summarizes key output fields for CoS rewrite rules.
Field | Values |
|---|---|
Rewrite rule | Name of the rewrite rule. |
Code point type | Rewrite rule type:
|
Index | Internal index for the rewrite rule. |
Forwarding class | Name of the forwarding class that is used to determine CoS values for rewriting in combination with loss priority. Rewrite rules are applied to CoS values in outgoing packets based on forwarding class and loss priority setting. |
Loss priority | Level of loss priority that is used to determine CoS values for rewriting in combination with forwarding class. |
Code point | Rewrite code point value. |
