Command Reference Guide

Administration Commands
define_ip_port
• 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.
implicit_deact_timer
Implicit limited resource link deactivation timer, in seconds.
If implicit_limited_resource is set to NO_SESSIONS, then the implicit link is automatically deactivated if no
data flows on it for the time specified by this parameter and no sessions are using the link.
If implicit_limited_resource is set to INACTIVITY, an implicit link using this port is automatically deactivated
if no data flows on it for the time specified by this parameter.
The minimum value is 5; values in the range 1–4 will be interpreted as 5. The value 0 (zero) indicates no
timeout (the link is not deactivated, as though implicit_limited_resource were set to NO). This parameter is
reserved if implicit_limited_resource is set to NO.
implicit_uplink_to_en
This parameter applies only if the local node is a Branch Network Node; it is reserved if the local node is
any other type.
If the adjacent node is an end node, this parameter specifies whether implicit link stations off this port are
uplink or downlink. This parameter is ignored if there are existing links to the same adjacent node, because
in this case the existing links are used to determine the link type. Possible values are:
YES
Implicit links to an End Node are uplinks.
NO
Implicit links to an End Node are downlinks.
effect_cap through user_def_parm_3
Default TG characteristics used for implicit link stations using this port and as the default TG characteristics for
defined link stations that do not have explicitly defined TG characteristics. The TG characteristics parameters
are ignored if the LS is to a downstream PU.
For more information about these parameters, see Section 2.32, define_ip_ls.
initially_active
Specifies whether this port is automatically started when the node is started. Possible values are:
YES
The port is automatically started when the node is started.
NO
The port is automatically started only if an LS that uses the port is defined as initially active; otherwise,
it must be manually started.
implicit_ls_limit
Specifies the maximum number of implicit link stations which can be active on this port simultaneously,
including dynamic links and links activated for Discovery. Specify a value in the range 1–65,534 or specify
0 (zero) to indicate no limit. A value of NO_IMPLICIT_LINKS indicates that no implicit links are allowed.
