set dcb cn priority lldp

Use this command to enable or disable LLDP congestion notification on all ports.

Syntax

set dcb cn priority priority lldp {enable | disable}

Parameters

`priority`	Specifies a CNPV to which this congestion notification LLDP configuration is applied.
enable \| disable	Enables or disables LLDP for dynamic configuration of domain defense.

Defaults

Congestion notification LLDP is enabled by default for all CNPVs. The sending of LLDP CN TLVs is disabled by default for all CNPVs.

Mode

All command modes.

Usage

This global congestion notification LLDP setting is only used if the port-priority LLDP setting using the set dcb cn port-priority lldp is set to default.

LLDP, defined in the IEEE 802.1AB standard, can be used by congestion notification to control the operation of domain defense by:

Advertising the CNPVs supported on a bridge or end-station port
Determining whether a neighbor supports the same CNPVs as this port

Multiple instances of LLDP can be supported by a port. The instance used for domain defense defaults to the nearest bridge address. Priority choice, set using set dcb cn priority choice, must be set to auto for congestion notification LLDP to control domain defense on the device. If priority choice is set to auto and congestion notification LLDP is disabled, domain defense is set to edge on all ports.

The sending of congestion notification TLVs is enabled or disabled on a port using set lldp port tx-tlv specifying the congestion-notif option.

Examples

This example first sets the LLDP port-priority to default for all ports, and then disables the global LLDP CNVP setting for CNPV 3:

System(rw)->set dcb cn port-priority *.*.* 3 lldp default
System(rw)->set dcb cn priority 3 lldp disable
