Configuring Node Defaults 4-7
Session Type = Terminated and the same Local Subscriber ID and Remote Subscriber ID
as specified here in the NetView parameters.
Remote Subscriber ID
is a subscriber address for the remote end of an LLC2 session established for a
NetView connection. An
LLC2 Host record (described on page 9-18) must be created,
with Session Type = Originated , Local Subscriber ID = the Remote Subscriber ID spec-
ified here in the NetView parameters, and Remote Subscriber ID = the Local Subscriber
ID specified in the NetView parameters.
Maximum Bytes per Frame
must correspond to the PIU size configured on the NetView host (parameter
MAXDATA of macro PU in VTAM).
Local SAP Address
is a service access point (SAP) address used to identify the SmartSwitch to a NetView
host. This parameter is relevant only in a connection to a 3174 or AS/400-type setup
where a specific source SAP address is required. If the session will be run over a native
LLC2 frame relay interface, the parameter will be ignored.
Local MAC Address
identifies the local SmartSwitch to a NetView host. Like the local SAP address, this
parameter is relevant only in a connection to a 3174 or AS/400-type setup where a spe-
cific source MAC address is required. If the session will be run over a native LLC2
frame relay interface, the parameter will be ignored.
IDBLK
is used in conjunction with IDNUM in generating the Node field in an XID frame
(format 0 or 3) to establish a link station connection to the host. A further explanation
is provided under "
IDNUM ."
IDNUM
is used in conjuction with IDBLK in generating the Node field in an XID frame (format
0 or 3) to establish a link station connection to the host. If 0 is specified for both IDBLK
and IDNUM , the Node field of the XID will be provided by the attached device. (The
node will send an XID command to the remote node to indicate that the device should
be polled for an XID.)
T1
is the Reply Timer, which is used to detect the failure to receive a required acknowl-
edgment or response from the remote link station. The link station will start the timer
when it transmits one of these:
●
an Information LPDU (LLC protocol data unit).
●
a Command LPDU with the P bit set to B ' 1 .' (If this LPDU is sent while the timer
is already running, the link station will reset and restart it.)
The link station will reset T1 when it receives one of these:
●
A REJ (Reject) LPDU, provided a Command LPDU with P bit set to B ' 1 ' is not
outstanding.
●
A Response LPDU with the F bit set to B ' 1 .'
