set dcb cn priority

Use this command to configure an 802.1p priority as a congestion notification priority value and to optionally enable or disable auto choice mode for all ports on the switch.

Note

All set dcb cn priority based command options can be entered on a single command line. Command options include: creation, status, choice, alt-priority, defense, and lldp. Each option is detailed in this chapter with its own entry for purposes of clarity.

Syntax

Parameters

Defaults

If creation enable or disable is not specified, the created CNPV defaults to creation enable. The priority defaults to 6.

Mode

All command modes.

Usage

There are eight 802.1p values from 0 - 7. For the 7100-Series, the maximum number of CNPVs configurable on a port is seven. The maximum number of CNPVs configurable on a port depends upon the chassis. The SSA, S3, and S4 chassis support a maximum of seven CNPVs. The S6 and S10 chassis support a maximum of four CNPVs. For both the S- and 7100-Series, there must always be at least one alternate (non-CNPV) priority value per port. By default, a CNPV is created with auto creation enabled.

This command does not activate the CNPV. Use set dcb cn priority status to activate a CNPV on the switch.

Note

CNPVs do not exist on S-Series hardware bonding ports.
