NAME

       atmarp - administer classical IP over ATM connections

SYNOPSIS

       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] [null]
       atmarp -s ip_addr atm_addr [qos qos] [sndbuf bytes] [temp] [pub] [arpsrv]
       atmarp -d ip_addr [arpsrv]
       atmarp -V

DESCRIPTION

       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.

OPTIONS

       -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 recognized:

              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 specified.

              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 permanent.

              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.
