This value is the current operational status of this internal port-channel bundle as a whole. It matters on the internal port-channel formed by bundling several server-side backplane links between an I/O Module and a Fabric Interconnect because a bundle can remain operationally up even after losing some member links, so this field alone doesn't reveal a partial degradation the way operSpeed or the member-link table would. An operState of up on this port-channel combined with a reduced operSpeed is the signature of a bundle running in a degraded, partially-failed state rather than fully healthy.
