DESCRIPTION

20       atmarp  is  used to maintain the ATMARP table of the ATMARP demon.  The
21       table can be listed, new PVC and SVC entries can be added, and existing
22       entries  can  be  deleted.  In addition to that, atmarp is also used to
23       create new IP over ATM interfaces.
24
25       Note that the kernel has its own ATMARP table containing  only  entries
26       for destinations to which a connection exists. The table of atmarpd can
27       also contain currently unused entries.
28

OPTIONS

30       -a     list the current ATMARP table.
31
32       -c     create the specified IP interface. If the  interface  number  is
33              omitted,  the  operating system assigns the next free number and
34              atmarp prints the resulting  interface  name  (e.g.  `atm0')  on
35              standard output.
36
37       -q     sets  the QOS and the send buffer size to use as the default for
38              all VCs generated for that  IP  network  (ip_addr  must  be  the
39              address of the network).
40
41       -s     set  up  a PVC or create an SVC entry. The following options are
42              recognized:
43
44              qos qos
45                     uses the specified quality of service (see qos(7) for the
46                     syntax). UBR at link speed is used by default.
47
48              sndbuf bytes
49                     tries  to  set the send buffer to the specified number of
50                     bytes. A system default value is used if  sndbuf  is  not
51                     specified.
52
53              temp   does  not  mark the entry as permanent, i.e. it will time
54                     out and then be removed.
55
56              pub    publishes the entry (only relevant  for  ATMARP  server).
57                     ATMARP  requests  for  entries  not marked for publishing
58                     yield an ATMARP_NAK response.
59
60              null   uses NULL encapsulation instead of LLC/SNAP encapsulation
61                     on  the  PVC.  This  option  is  not  available for SVCs,
62                     because the  LLC/SNAP  header  is  required  to  identify
63                     ATMARP  packets. null also implies that the entry is per‐
64                     manent.
65
66              arpsrv identifies the entry pointing to the ATMARP server.  Note
67                     that  the  node  acting as the ATMARP server must have no
68                     ATMARP server entry in its ATMARP table.
69
70       -d     delete the specified ARP entry.  In order to prevent  accidental
71              deletion  of  the  ATMARP  server entry, the arpsrv flag must be
72              specified when deleting it.
73
74       -V     print the version number of atmarp on standard output and exit.
