Hi all,
Iam monitoring the cellular signal strenght and current band connected 24x7 of our customers.
We do this with SNMP and the application Paessler PRTG Network Monitor.
The OID`s i use to monitor for example the RSSI, RSRP and RSRQ are:
RSSI: 1.3.6.1.4.1.9.9.661.1.3.4.1.1.1.7006
RSRP: 1.3.6.1.4.1.9.9.817.1.1.1.1.1.1.7006
RSRQ: 1.3.6.1.4.1.9.9.817.1.1.1.1.1.2.7006
I found those OID`s with the CISCO-WAN-3G-MIB.mib
As you can see the last 4 numbers are always the same because they seem to refer to my cellular modem wich has a entPhysicalIndex of 7006 by default.
The problem iam facing is that whenever the router or cellular modem reboots that vallue will add up by +1 so it will be 7007 after a reload.
My monitoring tool PRTG will then generate an error message with: "No Such Instance" because the OID has been changed.
Is there a way to get a persistent entPhysicalIndex for my cellular modem so the OID will not change after a reload ?
I already tried snmp ifindex persist on my cellular0/2/0 interface but that doesnt help
Thanks in advance!
Kind regards,
Michael
