Too many interfaces when using snmp sensor on cisco 1841

Modified on 2025-06-10 12:07:04 +0200

I am trying to monitor my bandwidth on my Cisco 1841 which has the following interfaces:

FE0/0
FE0/1
Serial0/0/0:0
Serial0/0/0:1

When activating snmp sensor for bandwidth, it finds 3 sub-interfaces for the FE0/1:

FE0/1/1
FE0/1/2
FE0/1/3

Where did these come from? they even show traffic on them.

How can I know which is the real interface?

Thanks in advance,

Ori

what in the config would create 'ghost' subinterfaces? I do not have any sub-interfaces on my FE0 or FE1.
