Defining Connectivity Components

Defining Ports, DLCs, and Connection Networks

Consult your SNA network planner if you do not know how to configure any of these parameters.

Additional Port Parameters for Token Ring, FDDI and EthernetLocal SAP number

The address of the SAP, usually 04. Use a different value only if you need to use more than one SAP on the card.

The SAP number must be a multiple of 4.

If you do not know what value to enter for this field, contact your SNA network planner.

Define on connection network

Whether the SAP is to access the LAN as a connection network. Defining a connection network enables links between nodes on the connection network to be started dynamically, without prior configuration.

This field applies only if the local node is not a LEN node, because LEN nodes cannot use connection networks.

CN name

The name of the connection network. You do not need to enter the CN name unless you specified the Define on connection network option to define the SAP on a connection network. The CN name is used as the name of a virtual routing node in order to establish links between the nodes on the connection network.

Specify the same CN name on all nodes on the connection network.

Additional Port Parameters for X.25 (QLLC)Match incoming X.25 address

The link address of the remote station (only needed if you want to restrict incoming data traffic). For a SpiderX25 port, you can configure an incoming match address. If you supply this value, incoming call packets are accepted only if they specify an address that starts with the configured address.
