atmifmp - Configures the ATM subsystem for switching IP
traffic only
/usr/sbin/atmifmp command arguments
Arguments can appear in any order after the command. All
required arguments must be specified.
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 [Toc] [Back]
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 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 [Toc] [Back]
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 [Toc] [Back]
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 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.
Specifies the ips interface.
Displaying or Clearing IP Switching Statistics [Toc] [Back]
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 [Toc] [Back]
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.
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.
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.
