HP-UX SNAplus2 R7 Administration Command Reference

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,orBACK_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.
