Change interface ID of device to access SNMP

RouterOS General
1

Hello,

I try to monitor the wireless signal strength of about 40 RB/411.
I use Nagios to access the RB/411s per SNMP.

Most of the RB/411 have OID:
.1.3.6.1.4.1.14988.1.1.1.1.1.4.2

only two of them have OID:
.1.3.6.1.4.1.14988.1.1.1.1.1.4.5

All the RB/411 have the same configuration and only one wlan card installed.
So why is the device interface ID sometime “2” and sometimes “5”?

Is it possible to change these IDs to the same value ???

Regards
Hardy
