[abriscoeexec]

Any Idea of what the problem could be ?

The possible problems for the error

Code: Select all

no response received

are most likely the following:
incorrect IP
incorrect community string for the device (currently you are using 'public')
incorrect SNMP version support (you are currently trying 2)
The device doesn't have SNMP enabled

[abriscoeexec]

the device has snmp enabled with Public string and snmp 2c .We migrating from PRTG to Nagios and all devices are currently figured and working on PRTG . We just cannot get the SNMP to work on Nagios

What is the make and model of the device you are trying to poll using SNMP?
It it is a firewall, you may need to setup an access rule to allow the XI server access to SNMP.

Can you run a snmpwalk and an nmap command from the Nagios server and post the output here?

Code: Select all

snmpwalk 10.0.15.15 -v 2c -c public
nmap 10.0.15.15 -p 161 -sU
