We are in the process of upgrading our server to 9.x and noticed this post:
We ran into the UNKNOWN interfaces issue quite a bit, do I need to enable "snmp-server ifindex persist"
for it to not do that on 9.x ?
thanks.
Anyone?
i experienced this same problem long before even using Solarwinds. my issues came about with Cisco IOS re-indexing the interfaces if the device was power cycled.
and discovered if you want it globally & always indexed then use the statement "snmp-server ifindex persistence" on the router.
here's something i found on Cisco:
The "snmp-server ifindex persistence" global configuration command enables and disables ifIndex persistence for all interfaces on the routing device (this applies only to interfaces that have ifDescr and ifIndex entries in the ifIndex table of the IF-MIB).
i can't recall a single router interface showing up Unknown yet, so that tells me our PERSISTS statements are working...so my advice is to use that statement in any Cisco router.
