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
