Modifying SNMP Configuration

/etc/config/snmpd.conf

The net-snmpd is an extensible SNMP agent, which when enabled should run with a default configuration. Its behavior can be customized via the options in /etc/config/snmpd.conf.

Changing standard system information such as system contact, name and location can be achieved by editing /etc/config/snmpd.conf file and locating the following lines:

sysdescr “opengear”

syscontact root <root@localhost>(configure /etc/default/snmpd.conf)

sysname Not defined (edit /etc/default/snmpd.conf) syslocation Not defined (edit /etc/default/snmpd.conf)

Simply change the values of sysdescr, syscontact, sysname and sysloca- tion to the desired settings and restart snmpd.
