PRTG/ snmp doesn't seem to work properly on Cisco Firepower FTD 2100

Hi,

We are setting up MRTG to monitor the firewall interface usages.

snmp-server host eof-cth 10.33.192.25 community ***** version 2c udp-port 161
snmp-server host ABCD 10.33.192.25 community ***** version 2c udp-port 161
no snmp-server location
no snmp-server contact
snmp-server community *****

It doesn't work properly. the firewall have 4 active interfaces that normally have traffic 100 Mbps. But the result on MRTG shows only one interface using around 400 Mbps.

Could you advise?

My firewall model is:

Cisco Fire Linux OS v6.6.0 (build 37)
Cisco Firepower 2110 Threat Defense v6.6.0 (build 90)
Thanks

Loc

 - Are  you sure you are monitoring the correct and or active-used interfaces ? You may want to snmp walk ifOperStatus from the IF-MIB,                                                  and correlate required interface-oid's accordingly.
