Node: node01 Alert ID: SwitchIslIfDownWarn_Alert Resource: Link Aggregate 1 Severity: Major Indication Time: Mon Jul 21 12:14:54 2025 Suppress: false Acknowledge: false Probable Cause: The cable attached to the ISL port "sw3/ Link Aggregate 1" with the description of "" might be faulty. For the port-channel, please check each individual link. Possible Effect: Inter- or Intra- cluster redundancy might be lost.

Corrective Actions: 1) Check whether the cable is fully inserted into the interface port on both ends. 2) Reconnect the ISL port using another cable. After reconnecting it, verify whether the link of the ISL port is up by executing the commands per the switch configuration guide or by checking whether the Link status LED is on.
