Administration Commands
define_qllc_ls
This TG number is used to represent the link when the link is activated. The node does not accept any other
number from the adjacent node during activation of this link; if the adjacent node is using preassigned TG
numbers, the same TG number must be defined by the adjacent node on the adjacent link station.
If the local node is a LEN node, or if the adjacent node is a LEN node and the link is de
fined to automatically
activate, set the TG number to
1. Otherwise, specify a number in the range 1–20,or0 (zero) to indicate
that the TG number is not preassigned and is negotiated when the link is activated.
If a preassigned TG number is defined, the
adj_cp_name parameter must also be defined, and the adj_cp_type
parameter must be set to either END_NODE or NETWORK_NODE.
limited_resource
Specifies whether this link station is a limited resource and is automatically deactivated when there are no
sessions using the link. Link stations on a nonswitched port cannot be configured as limited resource. Possible
values are:
NO
The link is not a limited resource and is not automatically deactivated.
NO_SESSIONS
The link is a limited resource and is automatically deactivated when no active sessions are using it.
INACTIVITY
The link is a limited resource and is automatically deactivated when no active sessions are using it, or
when no data has flowed on the link for the time period specified by the link_deact_timer parameter.
• If no SSCP-PU session is active across the link, the node deactivates the link immediately.
• If an SSCP-PU session is active but no traffic has flowed for the specified time period, the node
sends REQDISCONT(normal) to the host. The host is then responsible for deactivating all LUs and
the PU, at which time the local node will deactivate the link. However, the host may not deactivate
LUs with active PLU-SLU sessions; in this case, the link remains active until all these sessions are
deactivated (for example by the user logging out). This behavior can be changed by using options
in the ptf parameter of the start_node command.
A limited resource link station can be configured for CP-CP session support by setting this parameter to
NO_SESSIONS and cp_cp_sess_support to YES. In this case, if CP-CP sessions are brought up over the link,
SNAplus2 does not treat the link as a limited resource (and therefore does not deactivate it).
solicit_sscp_sessions
Specifies whether to request the adjacent node to initiate sessions between the SSCP and the local CP and
dependent LUs. This parameter is used only if the adjacent node is an APPN node (adj_cp_type is either
NETWORK_NODE or END_NODE); it is ignored otherwise. If the adjacent node is a host (adj_cp_type is either
HOST_XID3 or HOST_XID0), SNAplus2 always requests the host to initiate SSCP sessions.
Possible values are:
YES
Request the adjacent node to initiate SSCP sessions.
NO
Do not request the adjacent node to initiate SSCP sessions.
If the adjacent node is an APPN node and dspu_services is set to a value other than NONE, this parameter
must be set to NO.
pu_name
Name of the local PU that uses this link. This parameter is required only if adj_cp_type is set to HOST_XID3
or HOST_XID0,orifsolicit_sscp_sessions is set to YES; it is ignored otherwise. This name is a type-A
character string starting with a letter.
