I am using snmpd on CentOS 6.3 and was giving a network range to the source for mapping community to security group.
com2sec mynetwork 192.168.0.0/23 centreon
Anyhow it is not working and I always get a timeout from the polling server. When I enter the exact ip of the polling server it works (192.168.3.180)
It even works if I enter the whole netmask (255.255.252.0)
Anyhow it should work according to documentation. Did I do anything wrong?
