RTCHK (ROUTING_CHECK) -- Test traffic between adjacent routers.
usage:  RTCHK [-N net.node_id|-DEV[ICE] dev-name [dev-num]] [-S n] [-DAT|-NODAT]


FORMAT

  RTCHK [options]


  RTCHK performs a simple test to verify that the router is able to pass packets
  to and from an adjacent router.  RTCHK is for use in a DOMAIN/BRIDGE internet.
  You must be logged onto a routing node in order to use RTCHK.

  Use  the -DEVICE option to specify a network controller to test. You must give
  a device type (e.g. RING, IIC) to the device option. The RTSVC  program,  with
  no command line options, shows you which network devices your node has.

  Older  versions  of  RTCHK used a different command line syntax to specify the
  type of network hardware checked. The old command line options still  work  in
  RTCHK version 9.5, but are no longer supported.

  For more information on RTCHK, see Managing DOMAIN Internets.


OPTIONS

  Default options are indicated by "(D)."

  -N net.node_id
                     Test packet transmission to and from  the  specified  node.
                     The  network  ID  'net'  must  be a network that the router
                     touches.  Not valid if -DEVICE is specified.

  -DEV[ICE] dev-name [dev-num]
                     Test  packet  transmission  over a specific network device.
                     Use the RTSVC  program  to  display  the  names  (used  for
                     'dev-name')  and controller numbers (used for 'dev-num') of
                     the network devices attached to your node.  Not valid if -N
                     is specified.

  -S n                Specify  the  number  of test packets to exchange with the
                     other router.  If -S  is  not  specified,  10  packets  are
                     exchanged.

  -DAT         (D)    Specify  that  each test packet carries 1024 bytes of test
                     data.

  -NODAT             Omit test data from the test packets.


EXAMPLES

  $ rtchk -n 3CE02A8.4851 -s 1000          Exchange 1000 test packets with
                                            node 4851 on network 3CE02A8.
                                            The router must be attached to
                                            that network.

  $ rtchk -nodat                           Exchange 10 short test packets
                                            with the other node attached to
                                            the IIC or T1 connection.

  $ rtchk -dev iic -s 100                  Exchange 100 test packets with
                                            the other node on the IIC or
                                            T1 network.
