NAME

atm atmarp - manipulate FORE IP Internet-to-ATM address mappings

SYNOPSIS

atm atmarp [ -N ] hostname

atm atmarp [ -N ] -a

atm atmarp -s hostname device vpi vci aal [encapsulation] [peak]

atm atmarp -l device vpi vci aal [decapsulation]

atm atmarp -d hostname

atm atmarp -x device vpi vci

atm atmarp -f

DESCRIPTION

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.

OPTIONS

-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.

NOTES

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).

CLUSTER CONSIDERATIONS

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.
