Description
The
SET LINK
command sets options for one or more or links. The options are link
enabled or disabled, link autoisolate, link checksum and link inactivity timeout.
The parameter
link-name
is the node from which connect attempts are to be
honored (or not). Note that disabling the link prevents incoming connections over
an established link. It only takes effect when new connect attempts are made. It
does not effect the ability to connect to a node whose link has been disabled. The
link-name
can be wildcarded.
The current state of the link can be displayed with the
SHOW LINK/STATUS
command. When looking at connection problems both ends of the link counters
should be used with the
SHOW LINK/COUNTER
command.

Any RTR node may disconnect a remote node if it finds the remote node is
unresponsive or congested. The normal behavior following such action is
automatic network link reconnection and recovery.
Node autoisolation allows a node (the isolator) to disconnect a congested or
unresponsive remote node (the isolatee) in such a way that when the congested
node attempts to reconnect it receives an instruction to close all its network links
and cease connection attempts. A node in this state is termed isolated.
Some applications require that a node which is suspected of causing congestion
(that is, not processing network data sufficiently quickly) is isolated from the
rest of the network, so as to cause minimum disruption. The node autoisolation
feature meets this requirement.
