           Severity: Major
    Indication Time: Mon Aug 14 14:14:58 2023
           Suppress: false
        Acknowledge: false
     Probable Cause: The cable attached to the ISL port "bes-sw1/ Link
                     Aggregate 10" 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.

                     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.
