Multiple Instances of Network Interface in Performance Monitor

MORE INFORMATION

The Network Interface object is specific to IP. The instances in the Network Interface counter refer to the loopback address (127.0.0.1), the network card (if any), the dial-out WAN wrapper for each device bound under RAS, and the dial-in WAN wrapper for each device bound under RAS. The instances will always list the loopback address 127.0.0.1 first and the remaining instances should match the binding order of the TCP/IP protocol. To view the binding order for TCP/IP, choose Control Panel Network and click the Bindings button. In the Show Bindings For list, select TCP/IP Protocol.

NOTE: If RAS does not use IP for a device, it is not counted.

For example: If you have IP running on a network card, an ISDN card (dial- in/dial-out), and one communications port (dial-out only), but you also have another communications port set to dial-in/dial-out but using only NetBEUI, you would have the following instances:

   Instance 1: Loopback adapter (127.0.0.1)
   Instance 2: Network card
   Instance 3: ISDN dial out
   Instance 4: ISDN dial in
   Instance 5: Modem dial out
