Does anyone know how to use SNMP to determine if the switchport mode of an interface in a Cisco 2950 switch is "access" or "trunk"? I have searched through the CISCO-C2900-MIB but cannot find any reference to this setting. I guess that his mode setting merely indicates whether or not outgoing frames have VLAN tags but I have not found any relevant OIDs that might be used to determine the mode.
