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 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.   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 num-
	      ber  that can be used for receiving IP switching traffic. The default value is the driver's maximum VCI value.  Specifies the small-
	      est VCI number that can be used for transmitting IP switching traffic. The default value is the driver's minimum VCI value.   Speci-
	      fies  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 specified by the next argument. Information displayed includes the inter-
       face attachment state, the driver to which the interface is attached, the default SNAP VC, the interface and driver  receive/transmit/mini-
       mum/maximum 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
       interface.  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
       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.	Specifies the ips interface.  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 switch-
       ing  architecture is based on the Ipsilon Networks, Inc. reference model, and enables you to configure the Tru64 UNIX ATM subsystem to sup-
       port 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  sig-
       naling, Classical IP, or Local Area Network Emulation (LANE)). Multiple adapters are required.
