Configure settings to send notifications to an SNMP manager

The state of the network can be monitored through the Simple Network Management Protocol (SNMP). SNMP collects information by polling devices on the network or SNMP enabled devices send alerts to SNMP management stations. SNMP communities define the group that devices and management stations running SNMP belong to, which specifies where information is sent. The community name identifies the group.

1. Log in to the Administration settings on the ExtraHop system through https://<extrahop-hostname-or-IP-address>/admin.
2. In the Network Settings section, click Notifications.
3. Under Notifications, click SNMP.
4. On the SNMP Settings page, in the SNMP Monitor field, type the hostname for the SNMP trap receiver. Multiple names can be entered, separated by commas.
5. In the SNMP Community field, enter the SNMP community name.
6. In the SNMP Port field, type the SNMP port number for your network that is used by the SNMP agent to respond back to the source port on the SNMP manager.
   The default response port is 162.
7. Click Test Settings to verify that your SNMP settings are correct. If the settings are correct, you should see an entry in the SNMP log file on the SNMP server similar to the following:

   Connection from UDP: [192.0.2.0]:42164->[ 192.0.2.255]:162

   Copy

   Where 192.0.2.0 is the IP address of your ExtraHop system and 192.0.2.255 is the IP address of the SNMP server.

8. Click Save.
