The standard MIB variable ifOperStatus returns the logical and of the physical state and logical state. The physical state might be the carrier detect signal on a serial interface.

If you want to check routing table entries, us the ipRoutingTable.

The router will print a message on the console informing you it is shutting down an interface. Further the ifOperStatus variable should reflect the (now down) state of the interface. Further ifInErrors will increase. The locifCRC and locifAborts or whatever should also increase. Greg Satz cisco
