Introduction
The Interfaces window (see 
) shows the quantity of incoming and outgoing traffic, as well as errors 
that cause frames to be discarded for each of the local interfaces. The statistics listed on the access server 
Inter-
faces
 page comprise those contained in RFC 1213—Management Information Base for Network Management of 
TCP/IP-based internets: MIB-II. Frames are counted when they arrive on the network. Some frames are then 
discarded during error screening. The remaining frames are delivered to the appropriate higher layer or sub-
layer. Implementation of the Interfaces group is mandatory for all systems.

The Interfaces main window displays the total number (ifNumber) of network interfaces (regardless of their 
current state) present on this system. 
Number (ifIndex)
A unique number for each interface that ranges between 1 and the value of ifNumber. The value for each inter-
face must remain constant at least from one re-initialization of the entity’s network management system to the 
next re-initialization. Many MIB tables refer back to the interfaces table.
