Parameter Description
[1] (check box selected) = Enables SNMP manager
IP Address
[SNMPManagerTableIP_x]
Defines the IP address (in dotted-decimal notation, e.g.,
108.10.1.255) of the remote host used as the SNMP
manager. The device sends SNMP traps to this IP address.
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 101
Trap Enable
[SNMPManagerTrapSendingEnable_x]
Activates the sending of traps to the SNMP Manager.
[0] Disable
[1] Enable (Default)
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 99), 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 97). You can enhance security by configuring Trusted
