Remote node autoisolation may be enabled (at the isolator) where it applies to all
links using SET NODE/AUTOISOLATE, or for specific links only with the SET
LINK/AUTOISOLATE command. An isolated node (isolatee) remains isolated
until you carry out both of the following actions:
• Enable the link to the isolated node on all nodes that have isolated it, that is
set link [isolated-node]/enable
• Exit the isolated state on the isolated node, that is
Autoisolation is disabled (at the isolator) using the /NOAUTOISOLATE qualifier.
/CHECKSUM
/NOCHECKSUM (D)
specifies that checksum calculations for data packets over network
/CHECKSUM
links are performed. This qualifier is by default set to /NOCHECKSUM.
This command is useful for diagnosing errors over network links. To see the
checksum state, use the SHOW LINK/STATE command.
/ENABLE
/DISABLE
specifies that connect attempts are honoured from the node specified by
/ENABLE
.
link-name
This command is used to enable a link which is in a disabled state. A link can
be disabled either as a result of operator action, or automatically if it has been
suspected of causing severe congestion. If a link is automatically disabled, an
entry is made in the RTR error log.
specifies that connect attempts are no longer honoured from the node
/DISABLE
. Note that disabling the link does not have any immediate effect on an
link-name
established link. It only takes effect when new connection attempts are made.
/CLUSTER
/NOCLUSTER (D)
Specifies that the command is executed on all the nodes in the cluster.
If neither nor
/NODE /CLUSTER
nodes specified by the latest
command has been entered then the command is executed only on the node where
the command was issued.
Note: In environments that do not support clustering, use of the /CLUSTER
qualifier will cause the relevant command to be executed on the local node only.

to explicit link state queries. Link failover occurs between the adjustable
environmental timer parameters

stipulated and disconnects and retries the link according to the router preferences
