XID Command Examples

The following examples illustrate use of the XID command.

Example 1. Successful XID Response

NM> XID,08–00–09–00–02–5A,00<RETURN>

Perform Loopback Test thru node 08–00–09–00–02–5A.... [ok]

802.2 Basic Format, Class 1 Station : connectionless

NM>

In Example 1, an XID command is transmitted to a remote node (Station Address 08"00"09"00"02"5A). Because DSAP is •00" hex, the packet was directed to the LANIC card at that node; the remote system was not accessed. A proper response was received as verified by the

•[ok]" indication and the message describing the type of service provided by the card.

Example 2. No XID Response

NM> XID,08–00–09–00–02–5A,F8<RETURN>

Perform Loopback Test thru node 08–00–09–00–02–5A.... [failed]

–– > times out – no response from target node

NM>

In Example 2, an XID command is transmitted to the same node as Example 1, but the DSAP parameter F8 hex is specified. In this case, Node Manager is not running on the target node, and there is no response.
