Displaying the IfIndexes for ISDN
To display the ISDN IfIndexes, select Status/Statistics, WAN/Data Services, and ISDN from the navigation menu.
You will see the ISDN Signaling Statistics window. Look for the table in the center of the window.
The following WAN interface extension types relate to ISDN:
| isdns (5) | The physical interface type (S/T) of the ISDN circuit card; isdnu would designate a U-type circuit card. Take note of this IfIndex; ISDN configuring procedures may require this IfIndex number to identify the ISDN BRI service. |
| ds0 (6,7) | B-channel 1 or B-channel 2 of the ISDN BRI service. Each ISDN B-channel is represented by an IfIndex, even though the Passport 4400 currently supports only one B-channel. |
| lapd (8) | The ISDN D-channel data link layer (LAPD) interface. |
| isdn (9) | The signalling D-channel for the ISDN service. |
| propMultiplexor (153) | The physical port interface of the ISDN module. Note the third column (PPA) in the above display, which indicates the physical port (2). |
