DESCRIPTION
       atm  configures	and displays the status	of the Host ATM	Research Plat-
       form (HARP) networking software.	 The  subcommands  fall	 into  several
       categories:

       Interface  management  subcommands allow	manipulation of	the ATM	inter-
       face.  Functions	include	assigning a signalling manager	to  an	inter-
       face,  setting  the ATM address,	associating network interfaces with an
       interface, and displaying information about interfaces.

       VCC management subcommands allow	for managing ATM virtual channel  con-
       nections	 (VCCs).   Functions include opening and closing VCCs and dis-
       playing information about them.

       IP management subcommands allow for managing the	interface  between  IP
       and  the	 ATM  software.	 Functions include displaying and manipulating
       the ATMARP cache, opening a PVC connected to IP,	 assigning  an	ATMARP
       server  to  a  network  interface,  and displaying information about IP
       VCCs.

       Miscellaneous subcommands allow for displaying the version of  the  ATM
       software	and for	getting	help with the atm command.

   Signalling Managers
       The  signalling	manager	 is responsible	for the	opening	and closing of
       VCCs.  Four signalling managers are supported:

	    PVC	- for PVCs only,
	    SPANS - supports SPANS, FORE's proprietary signalling protocol,
	    UNI	3.0 - supports the signalling protocol from  The  ATM  Forum's
		 ATM User-Network Interface Specification, Version 3.0.
	    UNI	 3.1  -	 supports the signalling protocol from The ATM Forum's
		 ATM User-Network Interface Specification, Version 3.1.

       All four	signalling managers support the	opening	and  closing  of  PVCs
       (see the	add and	delete subcommands).

       A  signalling manager must be attached to a physical interface (see the
       attach subcommand) before any VCCs can be created on the	interface.

   Physical and	Network	Interfaces
       Two types of interfaces are supported: physical interfaces and  network
       interfaces.   A	physical  interface represents a physical point	of at-
       tachment	to an ATM network.  A physical interface has  an  ATM  address
       associated  with	it, except when	the PVC-only signalling	manager	is be-
       ing used.

       A network interface is a	logical	interface.  One	or more	network	inter-
       faces are associated with a physical interface;	each network interface
       has an IP address associated with it.  For  UNI-controlled  interfaces,
       there  can  be  up to 256 network interfaces associated with a physical
       interface.  In this case, the correspondence between the	network	inter-
       face  and the ATM address is determined by the selector field (the last
       byte) of	the physical interface's ATM  address.	 For  PVC-only	inter-
       faces,  there  can be up	to 256 logical interfaces associated with each
       physical	interface.  For	interfaces controlled by the SPANS  signalling
       manager,	 there	must  be one and only one network interface associated
       with each physical interface.

   Keyword and Documentation Conventions
       Command and subcommand keywords can be  abbreviated  by	simply	giving
       enough  of  the first part of the keyword to make it unique.  Thus, atm
       sh v gives the same result as atm show vcc.

       All keywords are	case-insensitive.

       Where a host address needs to be	given to the atm command, either a DNS
       name or an IP address in	dotted decimal format can be used.

       ATM  addresses are specified as strings of hex digits, with an optional
       leading "0x".  Fields within the	address	may be separated  by  periods,
       but  periods are	for readability	only and are ignored.  SPANS addresses
       are 8 bytes long, while NSAP-format addresses are 20 bytes  long.   The
       full  address,  including any leading zeroes, must be given.  For exam-
       ple:
	    0x47.0005.80.ffe100.0000.f21a.0170.0020481a0170.00 (NSAP format)
	    0x00000010.f2050aa9	(SPANS format)

SUBCOMMANDS
   Interface Management	Subcommands:
       atm add PVC _interface_ _vpi_ _vci_ _aal_ _encaps_ _owner_ ...

       the format of the add PVC subcommand varies depending on	the  owner  of
       the PVC.	 See the description under "IP Management Subcommands."

       atm attach _interface_ _sigmgr_

       where:
	    _interface_	 specifies  the	 physical  interface to	which the sig-
		 nalling manager is to be attached,
	    _sigmgr_ specifies which signalling	manager	 is  to	 be  attached.
		 Valid choices are "SIGPVC", "SPANS", "UNI30", and "UNI31".

       This command attaches a signalling manager to an	interface.  Until this
       is done,	VCCs cannot be opened or closed.  Only one signalling  manager
       at a time can be	attached to an interface.

       atm detach _interface_

       where:
	    _interface_	specifies the physical interface whose signalling man-
		 ager is to be detached.

       This command detaches a signalling manager from an interface.  All VCCs
       that the	signalling manager has created will be closed, and no new VCCs
       can be created until a signalling manager (either the same or a differ-
       ent one)	is attached again.

       atm set MAC _interface_ _MAC/ESI	address_

       where:
	    _interface_	 specifies the physical	interface whose	MAC address is
		 to be set,
	    _MAC/ESI address_ specifies	the 6-byte MAC part of	the  NSAP  ad-
		 dress	for  the interface.  The MAC address is	specified as a
		 string	of 12 hexadecimal  digits  with	 an  optional  leading
		 "0x".	Fields in the address may be separated by periods.

       This  command sets the MAC address for a	UNI-controlled interface.  The
       first 13	bytes (the prefix) of the 20-byte NSAP-format address are  set
       by  the atm set prefix command or the ILMI daemon (ilmid	(8)), the next
       6 bytes (the End	System Identifier (ESI)) are set by this command,  and
       the last	byte (the selector) will be determined by which	network	inter-
       face is to be associated	with the address.

       The atm set MAC command can be used to override the MAC address in  the
       interface hardware.

       atm set netif _interface_ _prefix_ _count_

       where:
	    _interface_	 specifies the physical	interface that the network in-
		 terface(s) are	to be associated with,
	    _prefix_ specifies the invariant part  of  the  network  interface
		 name,
	    _count_ specifies the number of network interface to be created.

       This command creates one	or more	network	interfaces and associates them
       with the	specified physical interface.  The network interface names are
       determined  by the prefix and the count.	 The names will	be of the form
       <prefix><nn>, where <prefix> is the prefix specified in the set subcom-
       mand and	<nn> is	a number in the	range 0	- <count>-1.  For example, the
       command:

	    atm	set netif hfa0 ni 2

       would create two	network	interfaces, named ni0 and ni1,	and  associate
       them with physical interface hfa0.

       atm set prefix _interface_ _NSAP	prefix_

       where:
	    _interface_	 specifies the physical	interface whose	NSAP prefix is
		 to be set,
	    _NSAP prefix_ specifies the	first 13 bytes of the NSAP address for
		 the  interface.  The prefix is	specified as a string of hexa-
		 decimal digits	with an	optional leading "0x".	Fields in  the
		 prefix	may be separated by periods.

       This  command  sets  the	 address  for a	UNI-controlled interface.  The
       first 13	bytes (the prefix) of the 20-byte NSAP-format address are  set
       by  this	 command,  the	next 6 bytes (the End System Identifier	(ESI))
       will be the MAC address taken from the physical interface or set	by the
       set MAC subcommand, and the last	byte (the selector) will be determined
       by which	network	interface is to	be associated with the address.

       The NSAP	prefix must be set before a UNI-controlled interface  can  be-
       come active.  This can be accomplished either by	the ILMI daemon	(ilmid
       (8)) or the set prefix subcommand.

       atm show	config [_interface_]

       displays	the following information:

       Interface - the name of the physical interface.

       Vendor -	the name of the	adapter	vendor.

       Model - the model of the	adapter.

       Media - the communications medium used by the adapter.

       Bus - the type of bus the adapter is attached to.

       Serial No.  - the adapter's serial number.

       MAC address - the MAC address of	the interface.	Note that this is  the
       MAC address encoded in the hardware of the adapter, even	if the atm set
       MAC command has been used to change the effective MAC  address  of  the
       interface.

       Hardware	 version  - the	hardware revision level	reported by the	inter-
       face.

       Firmware	version	- the firmware revision	level reported by  the	inter-
       face.

       If  no parameters are specified on the show config subcommand, the con-
       figurations of all physical interfaces will be displayed.  If an	inter-
       face  name  is specified, only the configuration	of the given interface
       is displayed.

       atm show	interface [_interface_]

       displays	the following information:

       Interface - the name of the physical interface.

       Sigmgr -	the name of the	signalling manager which has been attached  to
       the  interface.	 A dash	(-) is shown if	no signalling manager has been
       attached.

       State - the state of the	signalling manager for	the  interface.	  Each
       signalling manager has its own set of states.  They are:
	    PVC:
		 ACTIVE	--- The	signalling manager is active.
		 DETACH	--- The	signalling manager is being detached.
	    SPANS:
		 ACTIVE	--- The	signalling manager is active.
		 DETACH	--- The	signalling manager is being detached.
		 INIT ----- The	signalling manager's initial state.
		 PROBE ---- The	 signalling manager is attempting to make con-
			    tact with the ATM switch.
	    UNI	3.0 or UNI 3.1:
		 NULL ----- The	signalling manager's initial state.
		 ADR_WAIT - The	signalling manager is  waiting	for  the  NSAP
			    prefix to be set.
		 INIT ----- The	 signalling manager is attempting to establish
			    contact with the switch.
		 ACTIVE	--- The	signalling manager is active.
		 DETACH	--- The	signalling manager is being detached.

       ATM address - the ATM address of	the interface.

       Network interfaces - the	names of network interfaces, if	 any,  associ-
       ated with the physical interface.

       If no parameters	are specified on the show interface subcommand,	infor-
       mation about all	physical interfaces will be displayed.	If  an	inter-
       face  name  is specified, only information about	the given interface is
       displayed.

       atm show	netif [_netif_]

       displays	the following information:

       Net Intf	- the name of the network interface.

       IP Address - the	IP address of the network interface.

       If no parameters	are specified on the show netif	 subcommand,  informa-
       tion  about  all	network	interfaces will	be displayed.  If an interface
       name is specified, only information about the given  network  interface
       is displayed.

       atm  show stats interface [_interface_ [phy | dev | atm | aal0 |	aal4 |
       aal5 | driver]]

       displays	statistics associated with one or more	interfaces.   Subject-
       area keywords (phy, dev,	atm, aal0, aal4, aal5, or driver) can be spec-
       ified to	change the scope of the	statistics displayed.

       If no subject area keyword is specified,	the following  information  is
       displayed:

       Interface - the name of the physical ATM	interface.

       Input  PDUs  - the number of Protocol Data Units	(PDUs) which have been
       received	by the interface.

       Input Bytes - the number	of bytes which have been received by  the  in-
       terface.

       Input Errs - the	number of input	errors which the interface has experi-
       enced.

       Output PDUs - the number	of Protocol Data Units (PDUs) which have  been
       transmitted by the interface.

       Output  Bytes  -	the number of bytes which have been transmitted	by the
       interface.

       Output Errs - the number	of output errors which the interface has expe-
       rienced.

       Cmd Errs	- the number of	command	errors which the interface has experi-
       enced.

       If a subject-area keyword is specified, then statistics for  that  sub-
       ject  are  displayed.   The statistics displayed	depend on the adapter.
       If requested statistics are not available for an	adaptor, an error will
       be noted.

       If  no parameters are specified on the show stats interface subcommand,
       statistics for all ATM interfaces are displayed.	 If an interface  name
       is specified, only statistics for the given interface are displayed.

   VCC Management Subcommands:
       atm delete PVC _interface_ _vpi_	_vci_
       atm delete SVC _interface_ _vpi_	_vci_

       where:
	    PVC	specifies that the VCC to be closed is a PVC,
	    SVC	specifies that the VCC to be closed is an SVC,
	    _interface_	 specifies  the	physical interface at which the	VCC to
		 be closed terminates,
	    _vpi_ specifies the	Virtual	Path Identifier	(VPI) of the VCC,
	    _vci_ specifies the	Virtual	Channel	Identifier (VCI) of the	VCC.

       This command closes a VCC.  The two forms differ	only in	that the first
       specifies  that	the VCC	is a PVC (that was created by the add PVC sub-
       command)	and the	second specifies that the VCC  is  an  SVC.   Reserved
       VCCs (with VCI values less than 32) cannot be closed with this command.

       atm show	stats VCC [_interface_ [_vpi_ [_vci_]]]

       displays	the following information:

       Interface - the physical	interface on which the VCC terminates.

       VPI - the Virtual Path Identifier (VPI) for the VCC.

       VCI - the Virtual Channel Identifier (VCI) for the VCC.

       Input  PDUs  - the number of Protocol Data Units	(PDUs) which have been
       received	on the VCC.

       Input Bytes - the number	of bytes which have been received on the VCC.

       Input Errs - the	number of input	errors which the VCC has experienced.

       Output PDUs - the number	of Protocol Data Units (PDUs) which have  been
       transmitted on the VCC.

       Output  Bytes  -	the number of bytes which have been transmitted	on the
       VCC.

       Output Errs - the number	of output errors which	the  VCC  has  experi-
       enced.

       If  no  parameters are specified	on the show VCC	subcommand, all	active
       VCCs are	displayed.  If an interface name is specified, all active VCCs
       for  the	 given	interface  are displayed.  If an interface and VPI are
       specified, all active VCCs for the VPI on the given interface are  dis-
       played.	 If  an	interface, VPI,	and VCI	are specified, only the	speci-
       fied VCC	on the given interface is displayed (note that this could  ac-
       tually be two VCCs, since SPANS considers SVCs to be unidirectional).

       atm show	VCC [_interface_ [_vpi_	[_vci_]	| SVC |	PVC]]

       displays	the following information:

       Interface - the physical	interface on which the VCC terminates.

       VPI - the Virtual Path Identifier (VPI) for the VCC.

       VCI - the Virtual Channel Identifier (VCI) for the VCC.

       ues are null and	AAL 1-5.

       Type - specifies	whether	the VCC	is an SVC or a PVC.

       Dir - the direction of information flow on the VCC.  VCCs  can  be  in-
       bound, outbound,	or both.

       State  -	 the  state of the VCC,	as reported by the signalling manager.
       Each signalling manager has its own set of states.  They	are:
	    PVC:
		 NULL ----- No state.
		 ACTIVE	--- The	VCC is active.
		 FREE ----- The	VCC is closed and the  signalling  manager  is
			    waiting for	its resources to be freed.
	    SPANS:
		 NULL ----- No state.
		 ACTIVE	--- The	VCC is a PVC and is active.
		 ACT_DOWN - The	VCC is a PVC and the interface is down.
		 POPEN ---- The	VCC is being opened.

			    waiting for	its resources to be freed.
		 ACT_DOWN - The	VCC is a PVC and the interface is down.

       Encaps -	the encapsulation in effect on the VCC.	  Possible  encapsula-
       tions are null and LLC/SNAP.

       Owner - the owner or owners of the VCC.	Shows the name(s) of the func-
       tion(s) using the VCC.

       Destination - the ATM address of	the host at the	remote end of the VCC.

       If no parameters	are specified on the show VCC subcommand,  all	active
       VCCs are	displayed.  If an interface name is specified, all active VCCs
       for the given interface are displayed.  If an  interface	 and  VPI  are
       specified,  all active VCCs for the VPI on the given interface are dis-
       played.	If an interface, VPI, and VCI are specified, only  the	speci-
       fied  VCC on the	given interface	is displayed (note that	this could ac-
       tually be two VCCs, since SPANS considers SVCs to be unidirectional).

   IP Management Subcommands:
       atm add ARP [_netif_] _host_ _ATM address_

       where:
	    _netif_ is the optional name of the	network	interface  the	ATMARP
		 entry	is  to be associated with.  If no name is specified, a
		 network interface is chosen depending on the  IP  address  of
		 the host being	added.
	    _host_  is	the host name or IP address of the host	to be added to
		 the ATMARP table,
	    _ATM address_ is the ATM address of	the host.

       This command adds an entry to the ATMARP	 table	for  ATM.   The	 given
       host's  IP  address  is associated with the given ATM address.  When IP
       needs to	transmit data to the host, the specified ATM address  will  be
       used to open an SVC.

       The  entry will be marked as permanent in the ATMARP table and will not
       be subject to aging.

       atm add PVC _interface_ _vpi_ _vci_ _aal_ _encaps_ IP _netif_ [_host_ |
	    dynamic] _traffic_ _params..._

       where:
	    _interface_	 specifies  the	physical interface where the PVC is to
		 terminate,
	    _vpi_ specifies the	Virtual	Path Identifier	(VPI) of the PVC,
	    _vci_ specifies the	Virtual	Channel	Identifier (VCI) of the	PVC,
	    _aal_ specifies the	ATM Adaptation Layer (AAL) for the PVC.	 Valid
		 choices are "null" or "AAL0" for the null AAL;	"AAL1" for AAL
		 1; "AAL2" for AAL 2; "AAL3", "AAL4", or "AAL3/4" for AAL 3/4;
		 and "AAL5" for	AAL 5,
	    _encaps_  specifies	 the encapsulation for the PVC.	 Valid choices
		 are "null" or "none" for null encapsulation, and  "LLC/SNAP",
		 "LLC",	or "SNAP" for LLC/SNAP encapsulation,
	    IP specifies that the owner	of the PVC is IP.
	    _netif_ specifies the network interface which the PVC is to	be as-
		 sociated with.	 The network interface must exist and be asso-
		 ciated	with the specified physical interface,
	    _host_  |  dynamic gives the address of the	host at	the far	end of
		 the PVC, or the word "dynamic"	if its address is to be	deter-
		 mined	with Inverse ARP.  If "dynamic"	is specified, LLC/SNAP
		 encapsulation must also be specified.
	    _traffic_ is the traffic type of the PVC and may be	 one  of  UBR,
		 CBR  or  VBR.	Following the traffic type the traffic parame-
		 ters must be given.  For UBR and CBR this is  the  peak  cell
		 rate and for VBR these	are the	peak and sustainable cell rate
		 and the maximum burst size.

       This command creates a PVC with the specified attributes	 and  attaches
       it to IP.

       atm delete ARP [_netif_]	_host_

       where:
	    _netif_  is	 the optional name of the network interface the	ATMARP
		 entry is associated with.  If no name is specified, the spec-
		 ified	host is	deleted	from the cache regardless of what net-
		 work interface	it is associated with.
	    _host_ is the host name or IP address of the host  to  be  deleted
		 from the ATMARP table.

       This command deletes the	specified host's entry from the	ATMARP table.

       atm set arpserver _netif_ _ATM address_ | local [_IP prefix_ ...]

       where:
	    _netif_  specifies	the  network  interface	 for  which the	ATMARP
		 server	address	is to be set.
	    _ATM address_ specifies the	ATM address of the host	 which	is  to
		 provide  ATMARP  service.  If "local" is specified instead of
		 an ATM	address, the host on which the command is issued  will
		 become	the ATMARP server.
	    _IP	prefix_	... is an optional list	of IP prefixes that the	ATMARP
		 server	will provide information about.	 An IP prefix is spec-
		 ified	as  a  dotted decimal IP address, followed by a	slash,
		 followed a number specifying how many bits of the IP  address
		 are  significant.  For	example, 10.0.0.0/8 indicates that the
		 ATMARP	server will provide services for all addresses	on  IP
		 network  10.	The  IP	subnetwork which the network interface
		 belongs to is automatically included.

       This command sets the address of	the ATMARP server for a	network	inter-
       face.

       atm show	ARP [_host_]

       displays	the following information:

       Net Intf	- the network interface	which traffic for the entry will use.

       Flags - flags showing whether the entry is valid	and whether it is per-
       manent.	- flags	giving further information  about  the	ATMARP	entry.
       The meanings of the characters in the flags are:

	    P -	the entry is permanent
	    R -	the entry has been refreshed
	    V -	the entry is valid

       Age - the number	of minutes for which the entry will remain valid.

       Origin -	the source of the ATMARP entry.	 Possible values are:
	    LOCAL ---- The entry is for	an interface on	the host.
	    PERM ----- The  entry is permanent.	 This is used for entries that
		       are created with	the add	ARP command.
	    REG	------ The entry was created as	the result of a	host register-
		       ing with	the ATMARP server.
	    SCSP ----- The entry was learned via SCSP.
	    LOOKUP --- The  entry was created as the result of a host perform-
		       ing an ATMARP lookup.
	    PEER_RSP - The entry was created as	the result of a	host answering
		       an InARP	Request.
	    PEER_REQ - The  entry  was created as the result of	a host sending
		       an InARP	Request.

       ATM address - the ATM address of	the host the entry refers to.

       IP address - the	IP address or domain name of the host the entry	refers
       to.

       If  no  parameters  are specified on the	show ARP subcommand, the whole
       ATMARP table will be displayed.	If a host name or IP address is	speci-
       fied, only information about the	given host is displayed.

       This  command  displays	both information that has been learned dynami-
       cally (through one form or another of ATMARP and	via SCSP) and informa-
       tion which has been configured by the user (through the add ARP subcom-
       mand).

       atm show	arpserver [_netif_]

       displays	the following information:

       Net Intf	- the network interface	for which information  is  being  dis-
       played.

       State  -	 the  state  of	the connection to the ATMARP server.  Possible
       values are:
	    NOT_CONF - No ATMARP server	has been configured for	the interface.
	    SERVER --- The host	is the ATMARP server.
	    PEND_ADR - No ATM address has been set for the interface.
	    POPEN ---- The host	is attempting to open  a  VCC  to  the	ATMARP
		       server.
	    REGISTER - The  host has a VCC open	to the ATMARP server and is in
		       the process of registering with the server.
	    ACTIVE --- The ATMARP server connection is active.

       ATM Address - the ATM address of	the ATMARP server.

       If no parameters	are specified on the show  arpserver  subcommand,  the
       ATMARP servers for all network interfaces will be displayed.  If	an in-
       terface name is specified, only information about the given network in-
       terface is displayed.

       atm show	IPVCC [_host_ |	_netif_]

       displays	the following information:

       Net  Intf  -  the name of the network interface at which	the VCC	termi-
       nates.

       VPI - the Virtual Path Identifier (VPI) for the VCC.

       VCI - the Virtual Channel Identifier (VCI) for the VCC.

       State - the state of the	VCC.  Possible values are:
	    PMAP ---- The host has an IP packet	to send	and is waiting for  an
		      ATMARP mapping.
	    POPEN --- The VCC is being opened.
	    PACCEPT - A	VCC from a remote host is being	accepted.
	    ACTPENT - A	 PVC  is  open,	but no ATMARP information is available
		      for it yet.
	    ACTIVE -- The VCC is active.

       Flags - flags giving further information	about the VCC.	 The  meanings
       of the characters in the	flags are:

	    S -	the VCC	is an SVC
	    P -	the VCC	is a PVC
	    L -	the VCC	uses LLC/SNAP encapsulation
	    M -	the IP-to-ATM address mapping for the VCC is valid
	    N -	there is no idle timeout for the VCC

       IP  Address  - the name and IP address of the host at the remote	end of
       the VCC.

       If no parameters	are specified on the show IPVCC	subcommand, all	active
       VCCs are	displayed.  If a host name is specified, the active VCC(s) for
       the given host are displayed.  If a network interface  name  is	speci-
       fied, the active	VCC(s) for the given network interface are displayed.

   Miscellaneous Subcommands:
       atm help

       displays	 a  synopsis of	the atm	command	with its subcommands and their
       parameters.

       atm show	version	displays the version of	the running HARP software.
