The atm atmarp command displays and deletes FORE IP Internet-to-ATM
address translation table entries used by the
ATM address resolution protocol. It also allows IP traffic
to particular destinations to be routed over Permanent
Virtual Circuits (PVCs). This functionality is needed
only for special applications that may require the use of
PVCs for IP traffic. This program does not actually control
the creation of the PVCs.
If the single argument hostname is given, the ATM ARP
entry for hostname is displayed. When used with the -N
flag, the command displays the network address in numerical
form. When the -N flag is not specified, both the
symbolic and numerical forms are displayed.
- -a
- Display all of the current ATM ARP table
entries. When used with the -N flag, the
command displays the network address in
numerical form. When the -N flag is not
specified, both the symbolic and numerical
forms are displayed.
- -s
- Set ARP entry for outgoing Permanent Virtual
Channel (PVC). All traffic to host_name
will be encapsulated based on encapsu_lation
and sent via the device interface on
VPI vpi, VCI vci, using AAL type aal.
device must be a FORE IP device. Specifying
peak will limit all traffic to hostname
to peak kilobits per second. If peak is
not specified, no traffic shaping is
applied.
ARP entries for incoming and outgoing PVCs
persist even if an interface goes down
(whether because of an ifconfig down command
or a physical link being torn). The
only way to remove an ARP entry for an outgoing
PVC is to use atm atmarp -d or atm
atmarp -x.
- -l
- Attach IP to an incoming PVC. All traffic
received on the interface device with VPI
vpi, VCI vci, and AAL type aal will be
decapsulated based upon decapsulation and
handed up to IP. device must be a FORE IP
device.
- -d
- Delete address mapping for specified hostname
from the ATM ARP table. If an ATM
connection is open to the specified host,
then the connection is closed.
- -x
- Detach IP from an incoming SVC or PVC. IP
traffic will no longer be accepted on the
specified VPI and VCI.
- -f
- Delete all dynamic address mappings from
the ATM ARP table and close all Switched
Virtual Circuits (SVCs) to all hosts in the
table.
The allowed values for vpi, vci, aal, and peak will depend
on the capabilities of the ATM adapter used by the given
interface. In addition, certain adapters may only support
discrete peak cell rates. If so, the rate will be set to
the closest supported rate, which is less than the specified
rate.
encapsulation must be one of null (no encapsulation, the
default), llc_routed (IEEE LLC encapsulation for routed
PDUs), or llc_bridged_8023 (IEEE LLC encapsulation for
Ethernet/802.3 bridged PDUs). If encapsulation is specified
as llc_bridged_8023, the following argument must be
the 6-byte colon-separated destination MAC address.
decapsulation must be either null (no decapsulation, the
default) or llc (IEEE LLC decapsulation).
In takeover mode, the ForeIP/SPANS interface names are
those on the live filer, and in partner mode interface
names are those on the failed filer.
In takeover mode, this command affects only the arp
entries of the live filer, and in partner mode this command
affects only the arp entries of the failed filer.
