HP-UX SNAplus2 R7 Administration Command Reference

Administration Commands
define_sdlc_port
implicit_limited_resource
Specifies whether implicit link stations off this port are defined as limited resources. Possible values are:
NO
Implicit links are not limited resources and are not automatically deactivated.
NO_SESSIONS
Implicit links are limited resources and are automatically deactivated when no active sessions are using
them.
INACTIVITY
Implicit links are limited resources and are automatically deactivated when no active sessions are using
them or when no data has flowed for the time period specified by the
implicit_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.
implicit_hpr_support
Specifies whether High Performance Routing (HPR) is supported on implicit links. Possible values are:
YES
HPR is supported on implicit links.
NO
HPR is not supported on implicit links.
implicit_deact_timer
Implicit limited resource link deactivation timer, in seconds.
If implicit_hpr_support is set to YES and 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
