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.

Table 1: Summary of Key CoS Rewrite Rule Output Fields

Field

Values

Rewrite rule

Name of the rewrite rule.

Code point type

Rewrite rule type:

  • dscp—For IPv4 DiffServ traffic.

  • dscp-ipv6—For IPv6 Diffserv traffic.

  • ieee-802.1—For Layer 2 traffic.

  • exp—For MPLS traffic.

    Note:

    OCX Series switches do not support MPLS.

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.
