link

link

Use the link DLUR SAP configuration command to define and activate a link to a host. Use the no form of this command to delete the link definition.

link name [rmac rmac] [rsap rsap] no link name

Syntax Description

 

name

Link name, from one to eight alphanumeric characters. The

 

first character must be alphabetic. The name must be

 

unique within the DLUR function.

rmac

(Optional) Remote MAC address of the form

 

xxxx.xxxx.xxxx in hexadecimal. If not specified, a loopback

 

link to another SAP on the same internal LAN adapter is

 

assumed.

rsap

(Optional) Remote SAP address, 04 to FC in hexadecimal.

 

The rsap value must be even and should be a multiple of 4,

 

but this requirement is not enforced. The rsap value default

 

is 04.

Defaults

No DLUR link is defined.

The default remote SAP address is 04 (hexadecimal).

Command Mode

DLUR SAP configuration

Usage Guidelines

The combination of rmac and rsap must be unique within the DLUR SAP function. These values can only be changed by deleting the link definition, using the no link command, and recreating the link definition.

For a link via a channel on this CIP, the TN3270 server and the hosts should open different adapters in the same internal LAN. Using different adapters avoids any contention for SAP numbers, and is also necessary if you configure duplicate MAC addresses for fallback CSNA access to the host. By configuring the adapters in the same internal LAN, you achieve the same performance—bypassing the DLC stacks—as looping back on a single adapter.

Examples

The following command defines a link name and a remote SAP address:

link LINK5 rsap 08
