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 ), 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).
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.
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). 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).
➢ To configure SNMP Trusted Managers:
1. Open the SNMP Trusted Managers table (Setup menu > Administration tab > SNMP folder >
SNMP Trusted Managers).
