There used to be an example configuration in our documentation but it seems to not be there anymore.

Configuration is quite straightforward, just define a read only community and attach it to an access list only allowing your management station to reach it.

Jacek’s example is snmpv3, but you can use v2c too, it’s a little simpler.

Hello,

Nobody uses SNMP on CISCO ??

Objet : Best SNMP configuration for CISCO switch and router

Hello list,

What is the best SNMP configuration to use to feed back information from switch (Catalyst) and router (ASR) ?

I use the following configuration on my equipment but I wonder if there is not better (MIB) :

snmp-server group READONLY v3 priv read MIB-2 snmp-server view MIB-2 iso included

Thanks !

Oh yeah, this is functionally a requirement!

I recommend also using the ifindex persistence to prevent OID interface indexes changing after a reload.

snmp-server ifindex persist

Observium doesn’t handle traps.

 Hello all !

Thanks for your answers 😉

I take note of the important tip "snmp-server ifindex persist" to add on the switch and router !!

I also use an access-list to only authorize my OBSERVIUM server. The access-list is directly on the snmp-server user and not on the snmp-server group. I think it must come to the same ! (?)

snmp-server group READONLY v3 priv read MIB-2 snmp-server view MIB-2 iso included snmp-server user MY-USER READONLY v3 auth sha XXX priv aes 128 ZZZ access IP-OBSERVIUM ! ip access-list standard IP-OBSERVIUM permit A.B.C.D deny any !

Actually my question is more about the "snmp-server enable traps XXXXX" variant compared to "snmp-server view MIB-2 iso included"

I can't find a clear answer on both modes and also which one to integrate with Observium.
