I suspect that the switch probably only has one (logical)
network interface for communicating with the box itself.

Note that network interfaces as reported in the ifTable
are *not* necessarily the same as physical switch ports.

If you want to monitor which systems are connected to which
ports of the switch, you probably need to investigate the
BRIDGE-MIB (RFC 1493/4188), and in particular, dot1dTpFdbTable

But note that this is only concerned with *MAC* addresses.
A switch would typically be working at level 2, and would
not normally bother recording the IP addresses of traffic
it sees (even assuming that this traffic was IP-based in
the first place!)
