Administration Commands
define_ip_ls
•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.
disable_remote_act
Specifies whether to prevent activation of the LS by the remote node. Possible values are:
YES
The LS can be activated only by the local node; if the remote node attempts to activate it, SNAplus2 will reject the attempt.
NO
The LS can be activated by the remote node.
link_deact_timer
Limited resource link deactivation timer, in seconds. A limited resource link is automatically deactivated if no data flows over the link for the time specified by this parameter. This parameter is not used if limited_resource is set to any value other than INACTIVITY.
The minimum value is 5; values in the range 1–4will be interpreted as 5.
The value 0 (zero) indicates that the default deactivation timer value of 30 is used.
default_nn_server
For an end node this parameter specifies whether the link station being defined supports CP-CP sessions to a network node that can act as the local node’s network node server. When the local node has no CP-CP sessions to a network node server and needs to establish them, the local node checks this parameter on its defined link stations to find a suitable LS to activate. This enables you to specify which adjacent NNs are suitable to act as the NN server (for example, to avoid using NNs that are accessed by expensive or slow links).
Possible values are:
YES
This link supports CP-CP sessions to a network node that can act as the local node’s NN server; the local node can automatically activate this link if it needs to contact an NN server. The cp_cp_sess_support parameter must be set to YES.
NO
This link does not support CP-CP sessions to a network node that can act as the local node’s NN server; the local node cannot automatically activate this link if it needs to contact an NN server.
If the local node is not an end node, this parameter is ignored.
ls_attributes
Attributes of the remote system with which SNAplus2 is communicating.
Specify SNA unless you are communicating with a host of one of the other following types. Possible values are:
SNA
Standard SNA host
