atmifmp(8)							    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]

       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 Identi‐
	      fier (VCI) ranges available to the IP switching module (VPI 0 is
	      assumed).	  VCs  used  by	 the IP switching module are unidirec‐
	      tional.

	      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.
	      Specifies the ips interface number to create.  Specifies the ATM
	      driver associated with the virtual interface.  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.	 Specifies the
	      smallest VCI number that can be used for receiving IP  switching
	      traffic.	The  default  value is the driver's minimum VCI value.
	      Specifies the largest VCI number that can be used for  receiving
	      IP  switching traffic. The default value is the driver's maximum
	      VCI value.  Specifies the smallest VCI number that can  be  used
	      for  transmitting IP switching traffic. The default value is the
	      driver's minimum VCI value.  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

       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.  Specifies the ips interface.

   Displaying IP Switching Configuration
       Syntax:

       atmifmp showips [ips=num]

       Displays the state of all ips interfaces, unless an interface is speci‐
       fied 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/max‐
       imum VC ranges, and IFMP and Flow configuration information.  Specifies
       the ips interface.

   Displaying or Clearing IP Switching Statistics
       Syntax:

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

       Displays the flow and IFMP statistics for all ips interfaces, unless an
       interface  is specified by the next argument.  Specifies the ips inter‐
       face.  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]

       Displays flows created by the IP switching module  on  all  interfaces,
       unless an interface is specified by the next argument. Information dis‐
       played 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.  Specifies the ips interface.  Dis‐
       plays  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 sys‐
       tem, you cannot use that adapter to run ATM Forum protocols  (UNI  sig‐
       naling, Classical IP, or Local Area Network Emulation (LANE)). Multiple
       adapters are required.
