Cisco Firepower SNMP NAT OIDs

apoorva-ca · ‎04-15-2025

Hello,

Can someone help with OIDs for SNMP NAT monitoring on Cisco Firepower devices? Does Firepower support CISCO-NAT-EXT-MIB for NAT or is there a firepower specific mib to find NAT related metrics?

Thanks in advance!

- Looks like it is supported : ref => https://www.cisco.com/c/en/us/td/docs/security/firepower/70/configuration/guide/fpmc-config-guide-v70/snmp.html
Have a look at Table 5.

Thanks @marce for the info.

Looking at Table 5, I see that it lists only two OIDs under the CISCO-NAT-EXT-MIB. However, I’m also looking for a few additional NAT-related metrics such as its MappingProtocol, Failure Count, and PoolUtilization. From what I understand, these are likely available in the CISCO-IEFT-NAT-MIB.

Do you happen to know if Firepower supports the CISCO-IEFT-NAT-MIB ? Or, if you're aware of any relevant OIDs either within this MIB or another that could provide these metrics, please let me know if you’ve come across anything that could help.
