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

	    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."

       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>

       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.
		 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.

       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).

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

       AAL - the ATM Adaptation Layer (AAL) in use on the VCC.	Possible  val-
       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:

       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-

	    <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.

		 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).
       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:

	    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-
