Configuring Traffic Filters and Protocol Prioritization
3-8 117348-A Rev. A
DLSw Criteria and Actions
You can filter inbound DLSw traffic based on specified bit patterns in the DLSw
header, as defined in RFC 1434.
Predefined DLSw Criteria
Table 3-5 lists the predefined criteria for DLSw inbound traffic filters, and the
reference field, offset, and length for each criterion.
User-Defined DLSw Criteria
In addition to the predefined DLSw filter criteria, you can create inbound traffic
filters with user-defined criteria by specifying an offset and length to these
reference fields in the DLSw header:
DLSw Actions
The DLSw filtering actions are as follows:
Drop, Log -- Common to all inbound traffic filters
Forward to Peer -- Any frame that matches the filter will be sent to the
specified DLSw circuits
