Hello all.
For all the years I have worked with Cisco products, ASA's, FTD's, IOS routers I have had the same problem with SNMP. If you add, remove interfaces and reboot the ASA, FTD, Router the unit reorders the interfaces and numbers no longer match. When using a monitor tools like PRTG (we use) then wrong interface is logged. Solution is then to delete all interfaces and add them again.
Do you have this problem, and are there something I'm missing ?
tnx.

- In the configuration add :
router (config) # snmp-server ifindex persist

Many Cisco devices support "snmp-server ifindex persist", but this hasn't been implemented on ASA/FTD:
CSCtx33616 ENH: Need persistent interface indexes & OIDs while monitoring with SNMP
In case of FXOS persistence is supported by default:
CSCvx28168 DOC: SNMP IfIndex Persistence on FXOS
The end result is very platform and version dependent.
