Hello everyone. Currently we are trying to monitor the capacity of our NAT pools for our customers. We currently have around 450 NAT pools on the firewall.
I have noticed two OIDs that appear to be of use in monitoring this from "show snmp-server oidlist":
[231] 1.3.6.1.2.1.123.1.4.1.12. natAddrMapGlobalAddrTo
[235] 1.3.6.1.2.1.123.1.4.1.19. natAddrMapAddrUsed
Although we use Dynamic NAT we only NAT to one external IP per pool and not ranges of publics.
When I walk these I can clearly see my Global Addresses listed in Hex per value and a gauge value to match. There are several hundred of these:
iso.3.6.1.2.1.123.1.4.1.11.14.54 = Hex-STRING: C0 A8 01 01
iso.3.6.1.2.1.123.1.4.1.19.14.54 = Gauge32: 52
Note that the last value in the OID appears to change per pool (ranges from 1 - 400 usually).
The issue I am having is that if I do a "show xlate global 192.168.1.1" on the firewall I see a different amount of xlates displayed, sometimes several thousand off the result from the SNMPwalk.
Am I correlating the gauge value to the nat Xlate properly?
Thank you for your help.
