fcTrunkIfOperStatus
Cisco Fibre Element Trunk If Operation Status
1.3.6.1.4.1.9.9.289.1.1.3.1.1
The operational state of a VSAN on this port. If the port is in trunking mode, it is possible that the port state may be 'down(2)' only in some VSANs. If this port is down in this VSAN only then port state shown by 'ifOperStatus' may not be 'down(2)', but this object will show 'down(2)'. The 'fcTrunkIfOperStatusCause' object shows the reason for port being 'down(2)'.
