SNMP Settings
The SNMP setting determines whether your device settings can be viewed with standard SNMP software.
The default is disabled. For instance, one can see the device’s IP but not SysName, SysLocation, or
SysContact. In Fig 19, these three values viewing permission has been enabled, meaning granted. Of
these three fields, the first is SysName which is by default the MAC address; the second is the location of
the serial server; the third is the name of contact, usually the device administrator.
If you wish to make the information available for public viewing by a Read Community, simply check the
“Enable SNMP” box and fill in “Public_viewers” in Read Community field. If you wish to allow a group of
people called “Power_users” to change the information, enter “Power_users” in Write Community. If you
allow a trap server to collect device information, please fill in SNMP Trap Server with the IP address of the
trap server designed to collect all alarm information. The configuration will take effect after the device is
restarted.
