1 SHOW_PATH
!
Display the possible paths that node-to-node communication may take
through the network.  This allows you to determine what effect the
transition from Phase IV to DECnet-Plus has had on the network's
communication paths.

      SHOW PATH -
        [FROM = {node-name | osi-net | osi-area | ph4-addr | ph4-area }] -
        [TO   = {node-name | osi-net | osi-area | ph4-addr | ph4-area }] -
        [FORMAT = { BRIEF | FULL }] -
        [OUTPUT_FILE = output-file-name]

The command will dynamically determine what nodes might be traversed
when a packet is sent from a source node to a destination node, based
on information obtained from the starting node and from the routers in
the path.  It will then display the resulting lists of nodes.  More
than one possible path may be displayed.

All nodes in the path must be able to respond to either NICE or DNA CMIP
network management requests.

Example:  SHOW PATH TO .FR.CANNES FORMAT=FULL
!
2 FROM
!
This optional parameter allows you to specify the node to start at when
determining a set of communication paths.

You may enter either:

    FROM = node-name
    FROM = osi-net
    FROM = osi-area
    FROM = ph4-addr
    FROM = ph4-area

where:

    node-name   identifies the starting node using either the node's full
                DECdns name or its Phase IV synonym name.

                For example ".USA.Boston" or "BOSTON".

    osi-net     identifies the starting node using one of the node's network
                entity titles (NETs).  This may be entered in the format:

                    afi:idi:predsp-locarea:nodeid:sel

                For example "43:15084745192:00-0C:aa-00-04-00-50-30:00".

    osi-area    identifies the starting node using one of the node's
                network areas.  In this case, the first node found in
                the area becomes the starting node.  This may be entered
                in the format:

                    afi:idi:predsp-locarea

                For example "43:15084745192:00-0C".

    ph4-addr    identifies the starting node using the node's Phase IV
                network address.  This may be entered in the format:

                    area.nodeid

                For example "12.102".

    ph4-area    identifies the starting node using the node's Phase IV
                network area.  In this case, the first node found in the
                area becomes the starting node.  This may be entered in
                the format:

                    area.*

                For example "12.*".

If FROM is not specified, the starting node is assumed to be the local
node.  If TO is not specified, the terminating node is assumed to be
the local node.  You must specify at least one of these (they cannot
both be defaulted).

Example:  SHOW PATH FROM .USA.BOSTON TO .FR.CANNES
          SHOW PATH FROM 43:15084745192:00-0C:AA-00-04-00-50-30:00
!
2 TO
!
This optional parameter allows you to specify the node to stop at when
determining a set of communication paths.

You may enter either:

    TO = node-name
    TO = osi-net
    TO = osi-area
    TO = ph4-addr
    TO = ph4-area

where:

    node-name   identifies the terminating node using either the node's 
                full DECdns name or its Phase IV synonym name.

                For example ".USA.Boston" or "BOSTON".

    osi-net     identifies the terminating node using one of the node's
                network entity titles (NETs).  This may be entered in
                the format:

                    afi:idi:predsp-locarea:nodeid:sel

                For example "43:15084745192:00-0C:aa-00-04-00-50-30:00".

    osi-area    identifies the terminating node using one of the node's
                network areas.  In this case, the first node found in
                the area becomes the terminating node.  This may be
                entered in the format:

                    afi:idi:predsp-locarea

                For example "43:15084745192:00-0C".

    ph4-addr    identifies the terminating node using the node's Phase IV
                network address.  This may be entered in the format:

                    area.nodeid

                For example "12.102".

    ph4-area    identifies the terminating node using the node's Phase IV
                network area.  In this case, the first node found in the
                area becomes the terminating node.  This may be entered in
                the format:

                    area.*

                For example "12.*".

If TO is not specified, the terminating node is assumed to be the local
node.  If FROM is not specified, the starting node is assumed to be the
local node.  You must specify at least one of these (they cannot both be
defaulted).

Example:  SHOW PATH FROM .USA.BOSTON TO .FR.CANNES
          SHOW PATH TO 43:15084745192:00-0C:AA-00-04-00-50-30:00
!
2 FORMAT
!
This optional parameter allows you to specify the output format.  Formats
are:

    FORMAT = BRIEF  Display only the names of the nodes in the path.

    FORMAT = FULL   Display the node type and the NETs for each node
                    in the path.

If this parameter is not specified, the default is "BRIEF".

Example:  SHOW PATH FROM .USA.BOSTON TO .FR.CANNES FORMAT=FULL
!
2 OUTPUT_FILE
!
This optional parameter allows you to specify an output file.  If used,
the path information will be written to the output file rather than to
the terminal.

Example:  SHOW PATH FROM .USA.BOSTON TO .FR.CANNES OUTPUT=FRANCE.PATH
