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.
