This is an interface that is not managed by Orion, so we don't which interface it is. You could add all of the interfaces from the device, figure out which is exporting, then delete the rest.
On a 6500 series Cisco switch you can probably use
show snmp mib ifmib ifindex
Other Cisco boxes have similar commands to list the ifindexes of the interfaces. Then you can match up the ifindex number with the number in the Orion error message.
