Configuring SNA Resource Manager 46

Node Configuration

Node configuration is where you define the characteristics of each SNA Node

you want to activate on the gateway.

There are four Node types supported by Eicon SNA Gateway. Each Node type

provides services required to manage and use a particular type of device.

Important Notes

• When defining a Node, you must specify parameters to define the remote

peer Node addressing information, and reserve space on the Eiconcard for

Node resources.

• The Eiconcard can emulate up to thirty-two Nodes simultaneously. This

depends on available Eiconcard memory and the memory requirements of

the Node definition. Specifying a large Frame Size and many LUs increases

the amount of memory required by the Node.

• Eicon SNA Gateway supports up to 32 concurrent connections per

Eiconcard.

• When you define a Node with the Eicon Configuration Program, give it a

unique name. It is recommended that this name correspond to the IBM host

VTAM Node definition for easier overall network management.

Node Type Description

Node Type 1.0 Defines support services for 5250 Display and Printer devices

Node Type 2.0 Defines support services for 3270 Display and Printer devices, LU 0,

and dependent LU 6.2 types.

Node Type 2.1 Defines support for independent APPC/LU 6.2 types (peer-to-peer)

and APPN Low Entry Networking (LEN Node).

Node Type 5494 Defines support for 5250 Display and Printer devices over SDLC,
