atmifmp(8)
NAME
  atmifmp - Configures the ATM subsystem for switching IP traffic only

SYNOPSIS
  /usr/sbin/atmifmp command arguments

  Arguments can appear in any order after the command.	All required
  arguments must be specified.

OPTIONS
  This section is organized by the tasks you can perform with the atmifmp
  command.  Each task subsection provides the atmifmp command syntax and the
  options to use to complete the tasks.

  Enabling IP Switching

  Syntax:

  /usr/sbin/atmifmp attach ips=num driver=name [snapvci=vci] [rxmin=vci]
  [rxmax=vci] [txmin=vci] [txmax=vci]

  attach
      Creates a point-to-point, multicast-capable virtual interface on a
      driver as specified in the next two arguments. If the virtual interface
      already exists but is not currently attached (because it was previously
      attached and detached), the command creates an association between the
      virtual interface and the specified driver.

      The attach command also configures the Virtual Circuit Identifier (VCI)
      ranges available to the IP switching module (VPI 0 is assumed).  VCs
      used by the IP switching module are unidirectional.

      After the ips interface is attached, you must configure the interface
      using the ifconfig(8) command, specifying the source address of the
      host and destination address of the IP switch or another host
      associated with the point-to-point interface.

  ips=num
      Specifies the ips interface number to create.

  driver=name
      Specifies the ATM driver associated with the virtual interface.

  snapvci=vci
      Specifies the VCI number that Ipsilon Flow Management Protocol (IFMP)
      uses as the default SNAP VCI. The default VCI is 15. This number must
      match the VCI number used by IFMP on the destination host or switch
      associated with the point-to-point interface.

  rxmin=vci
      Specifies the smallest VCI number that can be used for receiving IP
      switching traffic. The default value is the driver's minimum VCI value.

  rxmax=vci
      Specifies the largest VCI number that can be used for receiving IP
      switching traffic. The default value is the driver's maximum VCI value.

  txmin=vci
      Specifies the smallest VCI number that can be used for transmitting IP
      switching traffic. The default value is the driver's minimum VCI value.

  txmax=vci
      Specifies the largest VCI number that can be used for transmitting IP
      switching traffic. The default value is the driver's maximum VCI value.

  Disabling IP Switching

  Syntax:

  /usr/sbin/atmifmp detach ips=num

  detach
      Disassociates the virtual interface, ipsnum, from the driver to which
      it was previously attached. Prior to detaching the interface, you must
      delete the ips interface's address and bring down the the ips interface
      using the ifconfig(8) command.

  ips=num
      Specifies the ips interface.

  Displaying IP Switching Configuration

  Syntax:

  atmifmp showips [ips=num]

  showips
      Displays the state of all ips interfaces, unless an interface is
      specified by the next argument. Information displayed includes the
      interface attachment state, the driver to which the interface is
      attached, the default SNAP VC, the interface and driver
      receive/transmit/minimum/maximum VC ranges, and IFMP and Flow
      configuration information.

  ips=num
      Specifies the ips interface.

  Displaying or Clearing IP Switching Statistics

  Syntax:

  /usr/sbin/atmifmp stats [ips=num] [clear]

  stats
      Displays the flow and IFMP statistics for all ips interfaces, unless an
      interface is specified by the next argument.

  ips=num
      Specifies the ips interface.

  clear
      Zeros the flow and IFMP statistics for all ips interfaces, unless an
      interface is specified. Statistics are displayed after they are
      cleared.

  Displaying IP Switching Flow Information

  Syntax:

  /usr/sbin/atmifmp flows [ips=num] [long]

  flows
      Displays flows created by the IP switching module on all interfaces,
      unless an interface is specified by the next argument. Information
      displayed for each flow includes the Flow ID, the transmit or receive
      VC associated with the Flow, the Flow Type, the number of packets sent
      or received, and VC aging information.

  ips=num
      Specifies the ips interface.

  long
      Displays additional information about each flow, such as the
      information encoded in the Flow ID.

DESCRIPTION
  The atmifmp command enables and disables IP switching on a Tru64 UNIX end
  system that has an attached ATMworks ATM adapter.  The IP switching
  architecture is based on the Ipsilon Networks, Inc. reference model, and
  enables you to configure the Tru64 UNIX ATM subsystem to support only IP
  traffic over an ATM network. The IFMP protocol associates an ATM virtual
  circuit with an IP data flow.

RESTRICTIONS
  If an ips interface is attached to a specific ATM adapter on your system,
  you cannot use that adapter to run ATM Forum protocols (UNI signaling,
  Classical IP, or Local Area Network Emulation (LANE)). Multiple adapters
  are required.
