Cisco Interface Trunk Status

Version 1

    Indicates if the port is actually trunking or
     not. In the case of ISL capable ports , the status
     depends on the success or failure of the
     negotiation process initiated by the port to
     become a trunk or non trunk.
     In the case of 802.10 capable ports , it is
     directly related to the on/off administrative
     status.

    This OID returns two values, 1 = trunking and 2 = notTrunking.  The MIB format is set to Enumeration so the table on the Node Details page should show trunking or notTrunking, not 1 or 2.
