The Target Rules section lists the SNMP parameters used when making SNMP requests to
ZoneRanger managed devices. The order of target rules is important. ZoneRanger selects the
first matching rule in the list, starting at the top. Use the arrow buttons to change the order of
the rules.
Discovery and SNMP polling use target rule parameters when sending SNMP Requests to
devices. The first rule whose Target matches the device address is used.
SNMP requests proxied through a Ranger Gateway use target rule parameters to govern
conversion between SNMP versions. When a proxied request is received from a Ranger
Gateway, the first rule whose Target matches the destination address and whose Community
matches the request community is used. If no rule is matched, SNMPv1 is used; that is,
SNMPv2c requests are converted to SNMPv1. Wildcards, specified by *, may be used at the
end of the community string. When using wildcards, the preceding portion of the community
string will be used for matching. If there is a match, the entire request community string is used.
Trap forwarding converts all SNMPv3 notifications to SNMPv2c or SNMPv1. The target rules
determine the community string to use for this conversion. The first rule that matches the source
address and user name from the SNMPv3 trap determines the community string in the
forwarded trap.
