Corrective Action

Minor

Ethernet Group with two Ethernet ports and only one is down.

"Ethernet link alarm.
LAN port number <n> link is down"

(where n is the port number)
1. Ensure that the Ethernet cables are plugged into the chassis.
2. Check the device’s Ethernet link LEDs to determine which interface is failing.
3. Reconnect the cable or fix the network problem

Minor

Ethernet Group with two Ethernet ports and both are down, or Ethernet Group with a single port and the port is down.

"No Ethernet link"

Cleared

Note: For High-Availability (HA) systems, the alarm's behavior is different when sent from the redundant or active device. The alarm from the redundant is sent when there is an operational HA configuration in the system. There is no Critical severity for the redundant module losing both its Ethernet links as that is conveyed in the no HA alarm that follows such a case.
