[Node-01 cshmd: hm.alert.raised:alert]: Alert Id = SwitchIslIfDownWarn_Alert , Alerting Resource = SW01(XXXXXXXXXXX)/Ethernet1/22/3 raised by monitor ethernet-switchSYSTEM-HEALTH-ALERT.XML：
Node: SW01
Alert ID: SwitchIslIfDownWarn_Alert
Resource: port-channel11
Severity: Major
Indication Time: Mon Jun 26 11:54:04 2023
Suppress: false
Acknowledge: false
Probable Cause: The cable attached to the ISL port "SW01(XXXXXXXXXXX)/port-channel11" 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.
