30.11 SNMP
Simple Network Management Protocol is a protocol used for exchanging management information
between network devices. Your USG supports SNMP agent functionality, which allows a manager
station to manage and monitor the USG through the network. The USG supports SNMP version one
(SNMPv1), version two (SNMPv2c) and version 3 (SNMPv3). The next figure illustrates an SNMP
management operation.

SNMP Management Model
Move To change an entry’s position in the numbered list, select the method and click Move to
display a field to type a number for where you want to put it and press [ENTER] to move
the rule to the number that you typed.
# This the index number of the service control rule.
The entry with a hyphen (-) instead of a number is the USG’s (non-configurable) default
policy. The USG applies this to traffic that does not match any other configured rule. It is
not an editable rule. To apply other behavior, configure a rule that traffic will match so the
USG will not have to use the default policy.
Zone This is the zone on the USG the user is allowed or denied to access.
Address This is the object name of the IP address(es) with which the computer is allowed or denied
to access.
Action This displays whether the computer with the IP address specified above can access the
USG zone(s) configured in the
Zone field ( Accept ) or not ( Deny ).
Apply Click Apply to save your changes back to the USG.
Reset Click Reset to return the screen to its last-saved settings.
