Question
How to implement Simple Network Management Protocol (SNMP) on PowerVM Virtual I/O Server (VIOS)
Cause
I need to strengthen network security on the VIOS.
Answer
VIOS supports OpenSSH for secure remote logins. It also provides a firewall for limiting access by ports, network services, and IP addresses.
SNMP v3 provides secure access by a combination of authenticating and encrypting packets over the network.
SNMP can be obtained from the VIOS Expansion Pack.
How to Configure SNMP on VIOS
How to Check Current SNMP Setting on VIOS
SNMP configuration settings are in /etc/snmpdv3.conf or /etc/snmpd.conf depending on v3 of SNMP is used or not. For example, the link below shows non-encrypted snmpd v3 is being used, so, /etc/snmpdv3.conf gets used
$ ls -l /usr/sbin/snmpd
lrwxrwxrwx 1 root system 9 Nov 9 2015 /usr/sbin/snmpd -> snmpdv3ne
How to Manually Start/Stop SNMP Daemon
$ startsrc -s snmpd
$ stopsrc -s snmpd
$ startsrc -s snmpd
$ stopsrc -s snmpd
