User's Manual 9. SNMP-Based Management
Trap Port
[SNMPManagerTrapPort_
x]
Defines the port number of the remote SNMP manager. The device
sends SNMP traps to this port.
The valid value range is 100 to 4000. The default is 162.
Trap User
[SNMPManagerTrapUser]
Associates a trap user with the trap destination. This determines the
trap format, authentication level, and encryption level.

v2cParams (default) = SNMPv2 user community string

SNMPv3 user configured in Configuring SNMP V3 Users on page
96
Trap Enable
[SNMPManagerTrapSendi
ngEnable_x]
Activates the sending of traps to the SNMP Manager.

[0] Disable

[1] Enable (Default)
9.4 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 94), 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 .
9.5 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 91). 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).
