User-Defined XNS Criteria
In addition to the predefined filter criteria, you can create traffic filters with
criteria you define by specifying an offset and length to the start of the XNS
header (XNS_BASE) as a reference field for a user-defined criterion.
XNS Actions
The XNS filtering actions are Accept, Drop, and Log.
OSI Criteria and Actions
You can configure OSI inbound traffic filters based on specified bit patterns
contained within the CLNP header.
Predefined OSI Criteria
Table 3-2 lists the predefined filtering fields for OSI inbound traffic filters and the
reference field, offset, and length value for each criterion.
