SNMP 6

Note: Only the New Filter page allows the Filter ID to be configured.

Filter ID – A user-defined name that identifies the filter. (Maximum length: 32 characters)

Subtree OID – Specifies MIB subtree to be filtered. The MIB subtree must be defined in the form “.1.3.6.1” and always start with a “.”.

Filter Type – Indicates if the filter is to “include” or “exclude” the MIB subtree objects from the filter. Note that MIB objects included in the filter are not sent to the receiving target and objects excluded are sent. By default all traps are sent, so you can first use an “include” filter entry for all trap objects. Then use “exclude” entries for the required trap objects to send to the target. Note that the filter entries are applied in the sequence that they are defined.

CLI Commands for Configuring SNMPv3 Trap Filters – To create a notification filter, use the snmp-server filter command from the CLI configuration mode. Use the command more than once with the same filter ID to build a filter that includes or excludes multiple MIB objects. To view the current SNMP filters, use the show snmp filter command from the CLI Exec mode.
