2.2.5 Configuring the SNMP Settings
Scrolling down in the Configure page reveals the "SNMP Settings" section (Figure 2.6).
Figure 2.6 - Typical Configure Page (upper-middle portion)
In the SNMP Setting block, under the "Basic" heading, set Read and Write Community to "public" and set Location to a meaningful name of your
choice. This entry will help you identify the specific Netlink board when multiple Netlink boards are installed on the same subnet. This entry will
be read by an SNMP system as "syslocation", OID .1.3.6.1.2.1.1.6. The port used for SNMP may also be changed in this section (161 Default).
Be sure to open the SNMP port if accessing SNMP outside your firewall. Below the port number setting, select the trap type (Trap or Inform).
Click the "Submit" button at the bottom of the "Basic" section to save the settings, otherwise you will lose the settings. These settings will take
effect after a reboot of the Netlink.
The "Security Name" section of the SNMP Setting block allows you to grant only specified computers (by IP address) SNMP v1 and v2
access. Since v1 and v2 do not have password protection, the Security Name settings add security to v1 and v2 access. The web server
is password protected and a user must have the web server password in order to setup a computer in the Security Name settings and
gain v1 and v2 access. Multiple source networks can be added to the Security Name Setting block. Be sure to click the "Submit" button
to save the settings. The settings will take effect after a reboot of the Netlink.
The "V3 User" section of the SNMP Setting block allows for a user to set up an SNMP v3 user name and password. With a user name
and password, the Netlink board may be accessed from anywhere via the internet by using the SNMP v3 protocol. No security name
setup is required for v3 users and multiple v3 users may be set up in the same table. Click the "Submit" button to save the settings,
which will take effect after rebooting the Netlink.
The SNMP Trap Receiver IP and Port settings should be set to the proper address for the SNMP Trap receiver. Click the "Submit" button
and reboot the Netlink for the settings to take effect. The SNMP Trap Version may be selected using "Select Trap Version". The SNMP
Inform Log may be seen by clicking the "Show Inform Log" button. If the trap type is set to "Trap", no data will be displayed in this
section. Click "Hide Inform Log" to hide the log window.
