How to check which snmp servers and flow-export are inactive (not in use) or have no counters traffic

[getaway51]

cm3dgbr# snmp-server host 192.168.2.33 version 2c read

cm3dgbr #ip flow-export destination 192.168.1.4 7775

Hello getaway51,

both SNMP in sending traps and netflow export use UDP that is connectionless.

This means the device will send traps for configured destination and netflow flow exports packets if it is able to route packets to respective destinations (including use of a default route). No feedback is expected from servers.

In order to understand if these servers are still operational you should contact the colleagues that manage them.

Hope to help

Hi,

is there any command to see the stats like snmp/flow traffic being send out?

[Giuseppe Larosa]

Hello,

for snmp

show snmp

should be enough look at SNMP traps sent counter.

for netflow

show ip flow export

should provide the desired info

However, the fact that these counters are non zero do not mean that the respective servers are actually working and listening on respective UDP ports as I explained in my previous post.

Hope to help

Giuseppe
