Syntax
snmp-server filter <filter-id> <include | exclude> <subtree>
[mask {mask}]
no snmp-server filter <filter-id> [subtree]
•filter-id - A user-defined name that identifies an SNMP v3 notification
filter. (Maximum length: 32 characters)
•include - Defines a filter type that includes objec ts in the MIB subtree.
•exclude - Defines a filter type that excludes objects in t he MIB subtree.
•subtree - The part of the MIB subtree that is to be filtere d.
•mask - An optional hexadecimal value bit mask to define objects in the
MIB subtree.

Command Usage
• The access point allows up to 10 notif ication filters to be created. Each
filter can be defined by up to 20 MIB subtree ID entries.
• Use the command more than o nce with the same filter ID to build a filter
that includes or excludes multiple MIB objects. Note that the filter entries
are applied in the sequence that they are defined.
• The MIB subtree must be defined in the form “.1.3.6.1” and always start
with a “.”.
• The mask is a hexadecimal value with each bit masking the corresponding
ID in the MIB subtree. A “1” in the mask indicates an exa ct match and a
“0” indicates a “wild card.” For example, a mask value of 0xFFBF provides
a bit mask “1111 1111 1011 1111.” If applied to the subtree
1.3.6.1.2.1.2.2.1.1.23, the zero correspon ds to the 10th subtree ID. When
there are more subtree IDs than bits in the mask, the mask is padded with
ones.
