atmifmp(8)atmifmp(8)NAMEatmifmp - 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.
