Administration Commands
define_tr_port, define_ethernet_port, define_fddi_port
• 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_link_lvl_error
Specifies whether HPR traffic should be sent on implicit links using link-level error recovery. This parameter
is ignored if implicit_hpr_support is set to NO. Possible values are:
YES
HPR traffic should be sent on implicit links using link-level error recovery.
NO
HPR traffic should not be sent on implicit links using link-level error recovery.
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, an 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.
