8.4 Configuring an SNMP Trap Destination with FQDN
Instead of configuring SNMP trap destinations (managers) with IP addresses in dotted-
decimal notation in the SNMP Trap Destinations table (see ''Configuring SNMP Trap
Destination with IP Addresses'' on page 89), you can configure a single SNMP trap
manager with an FQDN (e.g., mngr.corp.mycompany.com). The device sends the traps to
the DNS-resolved IP address. The resolved IP address replaces the IP address of the last
row (SNMP Manager 5) in the SNMP Trap Destinations table (and the last trap manager
entry in the snmpTargetAddrTable in the snmpTargetMIB).
Note: If you configure an FQDN for an SNMP trap manager:
• The device ignores your configuration in the SNMP Trap Destinations table.
• Only one SNMP trap manager can be configured.
 To configure an SNMP trap destination with an FQDN:
1. Open the SNMP Community Settings page (Setup menu > Administration tab >
SNMP folder > SNMP Community Settings).
2. Under the Misc. Settings group, in the 'Trap Manager Host Name' field
(SNMPTrapManagerHostName parameter), enter the FQDN.
3. Click Apply.
8.5 Configuring SNMP Trusted Managers
The SNMP Trusted Managers table lets you configure up to five SNMP Trusted Managers.
By default, the SNMP agent accepts SNMP Get and Set requests from any IP address as
long as the correct community string is used in the request (see ''Configuring SNMP
Community Strings'' on page 87). You can enhance security by configuring Trusted
Managers, which is an IP address from which the device's SNMP agent accepts and
processes SNMP requests. If no SNMP Trusted Manager is configured, any SNMP
manager can access the device (as long as the community string is correct).
The following procedure describes how to configure SNMP Trusted Managers through the
Web interface. You can also configure it through ini file (SNMPTrustedMgr_x) or CLI
(configure system > snmp settings > trusted-managers).
