SNMP

SNMP is a protocol for sending data and is used for monitoring. SNMP traps are alert messages sent as a result of monitoring conditions. SNMP trap receivers are configured to receive the alerts.

In the Logs & Monitoring > SNMP page you can do these actions:

• Turn the SNMP agent on or off

• Configure SNMP settings (system location, system contact, and community string for SNMP v1 and v2 authentication)

• Add SNMP v3 users

• Configure the settings for SNMP trap receivers

• Enable or disable SNMP traps that are sent to the trap receivers

SNMP must be set to ON to configure all SNMP settings (users, traps, and trap receivers).

To enable or disable SNMP:

1. Change the SNMP On/Off slider position to ON or OFF.

2. Click Apply.

To configure SNMP settings:

Click Configure.

The Configure SNMP General Settings window opens. You can enable SNMP traps, configure system location and contact details, and enable SNMP versions in addition to v3.

SNMP v3 Users

• To add a new SNMP v3 user, click New.

• To edit an existing SNMP v3 user, select the user from the list and click Edit.

• To delete an SNMP v3 user, select the user from the list and click Delete.

SNMP Traps Receivers

SNMP trap receivers receive the alert messages. The trap receiver properties must be configured before a trap is sent.

To add an SNMP trap receiver:

1. Click New.

2. In the Add SNMP Traps Receiver window, enter the IP address.

3. For a v2 trap receiver, enter the community name.

4. For a v3 trap receiver, enter the name of the defined SNMP v3 user.

To edit an existing SNMP trap receiver:

Select the trap receiver from the list and click Edit.

To delete an SNMP trap receiver:

Select the trap receiver from the list and click Delete.

SNMP Traps

You can enable or disable specified traps from the list and for some traps set a threshold value. The enabled traps are sent to the configured trap receivers.

Prerequisites: SNMP and SNMP traps must be enabled on the appliance.

SNMP Traps for VPN Tunnels

SNMP trap for VPN tunnels provides better monitoring of VPN tunnel status. For this specific trap, users are alerted when VPN tunnels go down. Currently, only VPN tunnels configured as Permanent Tunnels are monitored.

This feature is off by default. When the feature is enabled, the VPN tunnels status is periodically checked. If a tunnel is detected as down, an SNMP trap is sent to the user.

SNMP Traps for Hardware Sensors

SNMP traps for hardware sensors provide information on whether the sensor values are within their thresholds. Indicators are success or failure. These traps are on by default when SNMP traps are enabled and cannot be individually turned off or configured by the user.

To enable an SNMP trap:

1. In the list of SNMP traps, double-click the name of the trap.

   The SNMP Trap Configuration window opens.

2. Click Enabled.

   The trap details, including the monitored object, Trap OID and description, show.

3. Click Apply.

To edit an SNMP trap:

1. Select the trap from the list and click Edit.

2. Select the Enable trap option to enable the trap or clear it to disable the trap.

3. If the trap contains a value, you can edit the threshold value when necessary.

4. Click Apply.
