User-Defined IPX Criteria

In addition to the predefined filter criteria, you can create traffic filters with

user-defined criteria by specifying an offset and length to this reference field in the

IPX header:

IPX Actions

The IPX filtering actions are Accept, Drop, and Log.

LLC2 Criteria and Actions

You can filter inbound LLC2 traffic based on specified bit patterns in the LLC2

header.

Adding an IBM protocol to a circuit automatically adds LLC2. LLC2 traffic filters

apply to LLC2 routed over Frame Relay (also known as native SNA over Frame

Relay) and to any protocol running over LLC2, including Advanced Peer-to-Peer

Networking (APPN) and LAN Network Manager (LNM).

Predefined LLC2 Criteria

Table 3-9 lists the predefined criteria for LLC2 inbound traffic filters, and the

reference field, offset, and length for each criterion.

Reference Field Description

IPX_BASE Points to the first byte in the IPX header
