Interface Group – “ifIndex” Object (ifEntry 1)
This object provides the index into the ifTable and typically into tables in other

though not all indexes are supported for a particular model. When an
unsupported index is accessed, “noSuchName” is returned.
The following are the values of the ifIndexes for all DSU/CSU models:
1–Net T1
2–DTE T1
3–COM port
4–Modem port
5–Auxiliary RS-232 port
6–DCE port 1
7–DCE port 2
8–DCE port 3
9–DCE port 4
The supported ifIndexes for the 3162 DSU/CSU are:
Net T1
DTE T1
COM port
Auxiliary RS-232 port
DCE port 1
DCE port 2
