Congestion Notification Configuration Example

The following CLI input shows how to configure each switch for the dynamic domain defense as presented in Congestion Notification Domain Defense Mode Overview.

System(rw)->set dcb cn priority 6
System(rw)->set dcb cn priority 6 status enable
System(rw)->set lldp port tx-tlv congestion-notif *.*.*

This example assumes:

• This congestion notification configuration is a default configuration on all switches using LLDP to dynamically configure domain defense on all ports.
• That CoS priority 6 is mapped to transmit queue 6 on all ports within the congestion notification domain. Should there be other CNPV values configured, these may use transmit queue 6, but no non-CNPV priority is mapped to transmit queue 6.
  

  Note

  Congestion notification and congestion notification LLDP are globally enabled by default. A non-auto alternate priority is not configurable when using auto congestion notification.
