Use this command to configure a default method for selecting domain defense on all device ports for the specified congestion notification priority value.
| priority | Specifies the CNPV to which the specified congestion notification mode will be applied. |
| choice admin | auto | Configures the priority choice used by a port-priority when port-priority choice is set to default: admin – Domain defense is controlled by administratively configured values and defense mode defaults to interior on all ports. auto – Domain defense is automatically controlled by the port based upon neighbor information advertises by LLDP in the congestion notification TLV type 127. The global default setting for priority choice is auto. |
Priority choice defaults to auto. This is the global default setting.
All command modes.
If priority choice is set to auto, the domain defense mode defaults to edge. The defense mode will transition to interior-ready if congestion notification negotiation using TLV type 127 determines that the CNPV is activated on the neighbor. If priority choice is set to admin, the domain defense mode defaults to disabled. In this case no congestion notification will occur unless the domain defense is administratively changed.
This example sets the priority choice to admin for CNPV 3 for all ports on the device:
System(rw)->set dcb cn priority 3 choice admin
