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 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 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 encap_sulation
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.
