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
       attachment  to an ATM network.  A physical interface has	an ATM address
       associated with it, except when	the  PVC-only  signalling  manager  is
       being 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
		 address 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
		 interface(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
       become 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
       interface.

       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
       actually	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
       inbound,	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.
		 R_POPEN -- The	VCC is being opened by a remote	host.
		 OPEN ----- The	VCC is active.
		 CLOSE ---- The	VCC is being closed.

			    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
       actually	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
		 associated  with.   The  network  interface must exist	and be
		 associated 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
       interface name is specified, only information about the	given  network
       interface 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.
