Configuring an SNMP community
An SNMP community is a grouping of devices for network administration purposes. Within that SNMP community, devices can communicate by sending and receiving traps and other information. One device can belong to multiple communities, such as one administrator terminal monitoring both a firewall SNMP community and a printer SNMP community.
You can add an SNMP community to define a destination IP address that can be selected as the recipient (SNMP manager) of FortiAnalyzer unit SNMP alerts. Defined SNMP communities are also granted permission to request FortiAnalyzer unit system information using SNMP traps.
Each community can have a different configuration for SNMP queries and traps. Each community can be configured to monitor the FortiAnalyzer unit for a different set of events. You can also add the IP addresses of up to eight SNMP managers to each community.
To create a new SNMP community:
1. Go to System Settings > Advanced > SNMP v1/v2c.
2. Ensure that the SNMP Agent is enabled, and under Communities, select Create New.
The New SNMP Community dialog box opens.

3. Enter the below information as required.
Community Name
Enter a name to identify the SNMP community. If you are editing an existing community, you will be unable to change the name.
Hosts
The list of FortiAnalyzer that can use the settings in this SNMP community to monitor the FortiAnalyzer system. Select Add to create a new entry that you can edit.
 
IP Address
Enter the IP address of an SNMP manager. By default, the IP address is 0.0.0.0 so that any SNMP manager can use this SNMP community.
 
Interface
Select the name of the interface that connects to the network where this SNMP manager is located from the drop-down list. You need to do this if the SNMP manager is on the Internet or behind a router.
 
Delete icon
Select to remove this SNMP manager entry.
 
Add
Select to add a new default entry to the Hosts list that you can edit as needed. You can have up to eight SNMP manager entries for a single community.
Queries
Enter the port numbers (161 by default) that the FortiAnalyzer system uses to send SNMP v1 and SNMP v2c queries to the FortiAnalyzer in this community. Enable queries for each SNMP version that the FortiAnalyzer system uses.
Note: The SNMP client software and the FortiAnalyzer unit must use the same port for queries.
Traps
Enter the Remote port numbers (162 by default) that the FortiAnalyzer system uses to send SNMP v1 and SNMP v2c traps to the FortiAnalyzer in this community. Enable traps for each SNMP version that the FortiAnalyzer system uses.
Note: The SNMP client software and the FortiAnalyzer unit must use the same port for traps.
SNMP Event
Enable the events that will cause the FortiAnalyzer unit to send SNMP traps to the community. These events include:
• Interface IP changed
• Log disk space low
• HA Failover
• System Restart
• CPU Overusage
• Memory Low
4. Select OK to create the SNMP community.
