HP UX Internet and Networking Software manual HOSTXID0, Macaddress

Administration Commands

define_tr_ls, define_ethernet_ls, define_fddi_ls

HOST_XID0

The adjacent node is a host node; SNAplus2 responds to a polling XID from the node with a format 0 XID.

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.

mac_address

MAC address of the adjacent node.

If you need to define a non-selective listening LS (one that can be used only for incoming calls, but can have LUs defined on it to support dependent LU traffic), do not specify this parameter. The LS can then be used to receive incoming calls from any remote link station, but cannot be used for outgoing calls. There is no need to define a non-selective listening LS if only independent LU traffic is used, because an LS for independent LU traffic can be set up dynamically when required.

You will probably need to reverse the bit order of the bytes in the MAC address if the local and adjacent nodes are on LANs of different types (one Ethernet, the other Token Ring or FDDI) connected by a bridge. For more information, see Section 2.60.4, Bit Ordering in MAC Addresses. If the two nodes are on the same LAN, or on LANs of the same type connected by a bridge, no change in bit order is required.

lsap_address

Local SAP address of the adjacent node. Specify a multiple of 0x04 in the range 0x04–0xEC.

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 as automatically activated 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.
