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.
