Administration Commands

define_sdlc_ls

DSPU_XID

The adjacent node is a downstream PU; SNAplus2 includes XID exchange in link activation. The dspu_name and dspu_services parameters must also be set.

DSPU_NOXID

The adjacent node is a downstream PU; SNAplus2 does not include XID exchange in link activation. The dspu_name and dspu_services parameters must also be set.

If you want to run independent LU 6.2 traffic over this LS, you must set the adj_cp_type parameter to LEARN_NODE, END_NODE, NETWORK_NODE, or BACK_LEVEL_LEN_NODE.

address

Address of the secondary station on this LS.

The value of this parameter depends on how the port that owns this LS is configured, as follows:

•If the out_link_act_limparameter on define_sdlc_port is 0 (zero), the port is used only for incoming calls and this parameter is reserved.

•If the port is switched primary and is used for outgoing calls (port_type is PORT_SWITCHED, ls_role is LS_PRI, and out_link_act_lim on define_sdlc_port is a nonzero value), either set this parameter to 0xFF to accept whatever address is configured at the secondary station, or set it to a 1-byte value in the range 0x01–0xFE(this value must match the value configured at the secondary station).

•For all other port configurations, set this parameter to a 1-byte value in the range 0x01–0xFEto identify the link station. If the port is primary multi-drop (ls_role on define_sdlc_port is LS_PRI and tot_link_act_lim is greater than 1), this address must be different for each LS on the port.

auto_act_supp

Specifies whether the link can be automatically activated when required by a session. Possible values are:

YES

The link can be automatically activated.

The reactivation timer parameters are ignored. If the LS fails, SNAplus2 does not attempt to reactivate it until a dependent LU application that was using the session attempts to restart the session; an LS used by independent LUs is not reactivated by SNAplus2 and must be manually restarted.

The following restrictions also apply:

•If the link is to an APPN node, the LS must have a preassigned TG number defined (see the tg_number parameter), and cp_cp_sess_support must be set to NO.

•If either the local node or the adjacent node is an end node, the LS must also be defined to automatically activate at the adjacent node.

NO

The link cannot be automatically activated.

tg_number

Preassigned TG number. 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.

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 to be automatically activated, set the TG number to 1. Otherwise, specify a number in the range 1–20, or 0 (zero) to indicate that the TG number is not preassigned and is negotiated when the link is activated.
