LINESET Option
Time(Dist)
these entries show the time factor (TIME) and number of hops (DISTANCE) for
each path between systems in the network and the selected system. A value of inf
(--) (for infinite) indicates that there is no connection to the selected system. Each
row and column entry represents a path connecting the selected system to the
system listed in the leftmost column. (For more information on the TF, see
Routing
and Time Factors on page 17-22.) An asterisk (*) indicates the Expand line-handler
process selected for traffic to each known node in the network; this is also the line-
handler process used for the $NCP connection protocol with each node.
For multi-CPU paths, the asterisk has a different meaning for non-neighbor nodes
than for neighbor nodes. For non-neighbor nodes, the asterisk indicates the
Expand line-handler process selected for the pair between the local node and each
remote node; all traffic to the remote node uses the indicated line-handler process.
For neighbor nodes, traffic can also be directed to any of the other Expand line-
handler processes in the multi-CPU path; an asterisk in this case indicates the line-
handler process used for the $NCP connection protocol and an ampersand (&) is
shown beside the other members of the multi-CPU path.
Lset:LHname
Lset (lineset) indicates the path number, or lineset number. LHname is the name of
the line handler involved.
Ldev
indicates the logical device (LDEV) number associated with each line logical
device. After the LDEV number, an asterisk (*), or plus (+), or ampersand (&)
symbol indicates:
* indicates that the line is connected
+ indicates that the line is in the process of connecting
& indicates that the LDEV is a multi-CPU p

LINESET Option
The information displayed for the INFO PROCESS $NCP command with the LINESET
option is taken from $NCP’s path table. It is a subset of the information shown by the
NETMAP command. They both have an AT option to show information from the
viewpoint of another system.
$NCP updates its path table when it receives a READY or NOT READY message from
an Expand line-handler process. If an Expand line-handler process is not started after
a system load, then the line does not appear in $NCP’s path table and thus does not
appear in the display for the INFO PROCESS $NCP command with the LINESET
option.
