niffconfig(8) System Manager's Manual niffconfig(8) NAME
niffconfig - Configuration program for the Network Interface Failure Finder (NIFF) SYNOPSIS
/usr/sbin/niffconfig [-a] [-m] [-r] [-s] [-u] [-v] [-d num] [-o num] [-t num] [interface1 interface2...] OPTIONS
Adds an interface or interfaces, specified by the interface parameter. You cannot specify the -a option with the -m, -s, -r, or -u options. Specifies the time period, in seconds, that the traffic monitor thread uses between reads of the interface counters when it suspects there is a connectivity problem. This number must be smaller than the number given for the -t option. The default time period is 5 seconds. If num is not specified, niffconfig uses the default. Specifies the total number of traffic-free seconds that must elapse before the traffic monitor thread determines that a network interface has failed. This number must be at least the sum of the -d option and two times the -t option. That is, given the default time period for -d and -t, the -o option must be at least 20 seconds. The default time period for this option is 60 seconds. If num is not specified, niffconfig uses the default. Modifies the timing parameters of an interface that is already being monitored. Typically, this option is specified along with one or more of -t num, -d num, or -o num options. If none of these parame- ters are specified, the default value is used. You cannot specify the -m option with the -a, -s, -r, or -u options. Stops monitoring the specified interface. Obtains the status of the specified interface. Specifies the time period, in seconds, that the traffic monitor thread delays between reads of the interface counters when the network is running normally. The default time period is 20 seconds. If num is not specified, niffconfig uses the default. Displays the status of all interfaces currently being monitored to standard out (stdout). Displays the status, timer values, and description (verbose mode) of all interfaces currently being monitored to standard out (stdout). DESCRIPTION
The niffconfig command arranges for one or more network interfaces to be monitored for possible loss of connectivity. Timing parameters that govern how quickly an interface can be declared suspect or dead may be manipulated with this command. You can specify multiple inter- faces, separated by a space, on the command line. Note, you must be superuser to use the niffconfig command. Except for the -u and -u options, all niffconfig options require one or more network interfaces to be specified. EXAMPLES
To add the tu0 and tu1 interfaces to the list of monitored interfaces, enter: # niffconfig -a tu0 tu1 To change the time it takes to declare failure on the tu1 interface to 90 seconds, enter: # niffconfig -o 90 tu1 To display the status of all interfaces that are being monitored: # niffconfig -u To stop monitoring the tu0 interface: # niffconfig -r tu0 SEE ALSO

atmifmp(8) System Manager's Manual 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 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. SEE ALSO
