HP UX Internet and Networking Software manual Limitedresource

Administration Commands

define_sdlc_ls

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.

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, or if solicit_sscp_sessions is set to YES; it is ignored otherwise. This name is a type-A character string starting with a letter.

You cannot change the PU name on an LS that is already defined.

If the PU name is required and you do not specify it, the default PU name is the same as the LS name. To ensure that this name is a valid type-A character string, SNAplus2 converts it to uppercase; if the string begins with a numeric character, this character is either removed or preceded by the characters “PU.”

disable_remote_act

Specifies whether to prevent activation of the LS by the remote node. Possible values are:

185
