We have one port channel configured in our Customer environment. This port channel has been configured with 6x4Gbps ports inside it. One of the switch port started flapping (up & down) continuously, which caused multiple alerts on many hosts as well as drastic performance slowness on one of the Business Critical application. It caused a major issue and later on after disabling this port administratively, the issue got resolved.
Could you let me know the cause of major impact and port-channel behavior in such rare cases, where because of one port flapping, whole port channel got affacted ? Is it a expected behavor of port-channel of kind of software bug in Cisco MDS 9513 switches running SAN OS ?
