atmarp - manipulate FORE IP Internet-to-ATM address mappings
atmarp [ -N ] hostname
atmarp [ -N ] -a
atmarp -s hostname device vpi vci aal [encapsulation] [peak]
atmarp -l device vpi vci aal [decapsulation]
atmarp -d hostname
atmarp -x device vpi vci
atmarp -f
The atmarp program displays and deletes FORE IP Internetto-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 only needed 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
network address is displayed 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
network address is displayed 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 hostname will
be encapsulated based on encapsulation 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 atmarp -d or 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, the atmarp command only affects the arp
entries of the live filer, and in partner mode the atmarp
command only affects the arp entries of the failed filer.
