Description The XID is the ID of a device in the SNA world. Generally speaking, there are two
kinds of devices: PU2.0 and PU2.1. The XID has been automatically configured on the
PU2.1 devices and they can announce their IDs by exchanging the XID. The PU2.0
devices did not exchange the ID, so they can not get ID automatically. Therefore, this
command needs not to be configured on PU2.1 typed devices, whereas it is needed
to specify an XID for PU2.0 typed devices.
