       atmarp - administer classical IP over ATM connections


       atmarp -a
       atmarp -c [[atm]number]
       atmarp -q ip_addr [qos qos] [sndbuf bytes]
       atmarp -s ip_addr [itf.]vpi.vci [qos qos] [sndbuf bytes] [temp] [pub]
       atmarp -s ip_addr atm_addr [qos qos] [sndbuf bytes] [temp] [pub]
       atmarp -d ip_addr [arpsrv]
       atmarp -V


       atmarp  is  used to maintain the ATMARP table of the ATMARP demon.  The
       table can be listed, new PVC and SVC entries can be added, and existing
       entries  can  be  deleted.  In addition to that, atmarp is also used to
       create new IP over ATM interfaces.

       Note that the kernel has its own ATMARP table containing  only  entries
       for destinations to which a connection exists. The table of atmarpd can
       also contain currently unused entries.


       -a     list the current ATMARP table.

       -c     create the specified IP interface. If the  interface  number  is
              omitted,  the  operating system assigns the next free number and
              atmarp prints the resulting  interface  name  (e.g.  ‘atm0’)  on
              standard output.

       -q     sets  the QOS and the send buffer size to use as the default for
              all VCs generated for that  IP  network  (ip_addr  must  be  the
              address of the network).

       -s     set  up  a PVC or create an SVC entry. The following options are

              qos qos
                     uses the specified quality of service (see qos(7) for the
                     syntax). UBR at link speed is used by default.

              sndbuf bytes
                     tries  to  set the send buffer to the specified number of
                     bytes. A system default value is used if  sndbuf  is  not

              temp   does  not  mark the entry as permanent, i.e. it will time
                     out and then be removed.

              pub    publishes the entry (only relevant  for  ATMARP  server).
                     ATMARP  requests  for  entries  not marked for publishing
                     yield an ATMARP_NAK response.

              null   uses NULL encapsulation instead of LLC/SNAP encapsulation
                     on  the  PVC.  This  option  is  not  available for SVCs,
                     because the  LLC/SNAP  header  is  required  to  identify
                     ATMARP  packets.  null  also  implies  that  the entry is

              arpsrv identifies the entry pointing to the ATMARP server.  Note
                     that  the  node  acting as the ATMARP server must have no
                     ATMARP server entry in its ATMARP table.

       -d     delete the specified ARP entry.  In order to prevent  accidental
              deletion  of  the  ATMARP  server entry, the arpsrv flag must be
              specified when deleting it.

       -V     print the version number of atmarp on standard output and  exit.
