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.
