SNMP Timeout

Been getting a lot of SNMP timeouts lately. FreeBSD/Nagios has been up and running for 60 days. Mikrotik CCR has been up and running for 42 weeks (nope, no updates for a long time).

Today, we keep getting alarms that SNMP is timing out. I try it from the command line, and I get this:

$ snmpwalk -v2c -c SuperSecret 172.28.28.1 1.3.6.1.2.1.2.2.1.8
IF-MIB::ifOperStatus.1 = INTEGER: down(2)
IF-MIB::ifOperStatus.2 = INTEGER: up(1)
Timeout: No Response from 172.28.28.1

Trying several times, I’ll get a timeout right away, maybe I’ll get 5 or 6 interfaces. Usually, within a few minutes, the query will complete.

Profile shows 96.4% idle, SNMP at 0%.

Any ideas on why SNMP would be timing out?

I don’t care to upgrade (yet). This beast has been running fine for 42 weeks without this problem. I do not see why it would start acting up now.

Thanks!

Maybe try to reboot it. Sometimes such problems can be creep in over time.
(I have no experience with that particular router, but have seen it on other equipment)
