 NAME
      elstat - display ATM Lan Emulation Client (LEC) configuration, status
      and statistics.

 SYNOPSIS
      /usr/sbin/elstat -n net_interface -v

      /usr/sbin/elstat -n net_interface -s

      /usr/sbin/elstat -n net_interface -m

 DESCRIPTION
      The elstat command displays the primary and secondary LEC
      configuration, status information, statistics information and the
      registered multi-cast MAC addresses for the specified ATM LANE network
      interface.

      Refer to Configuration Information and Status Information sections for
      a detailed explanation of the information displayed.  You can also get
      information on these by looking into the ATM Forums : LAN Emulation
      over ATM Version 2 - LUNI Specification, and LANE Client Management
      Specification Version 2.0.


    Options
      elstat recognizes the following options:

	   -m		     Display the list of registered multi-cast MAC
			     addresses for the given interface.

	   -n net_interface  Specifies the network interface name. There is
			     no default.  The netstat -i command can be used
			     to display the name of each interface that is
			     associated with an ATM adapter. Refer to the
			     netstat(1) man page for more information.

	   -s		     Display primary LEC and secondary LEC
			     statistics.

	   -v		     Display primary LEC and secondary LEC
			     configuration and status information.

    EXAMPLE
      A sample output of the "elstat -n e1100 -v" command is as shown below.

      elstat -n el100 -v

    Configuration Information
	   ATM Address
		This is the ATM address of the LAN Emulation Client (LEC),
		which accepts non-multiplexed VCCs.


	   LLC multiplexed ATM Address
		This is the ATM address of the LEC, which accepts LLC-
		multiplexed VCCs.


	   MAC Address
		This is the unicast MAC address associated with the LEC.
		Two LECs joined to the same emulated LAN MUST NOT have the
		same local unicast MAC address.


	   Local Segment ID
		The 12-bit source routing segment ID of the Emulated LAN
		(ELAN).	 This is only required for IEEE 802.5 LECs that are
		Source Routing bridges.


	   ELAN name
		The identity of the ELAN the LEC wishes to join, or to which
		the LEC last joined.


	   Status
		This gives the operational status of the ELAN interface.
		The status can be either "Operational" or "Not Operational".





 Hewlett-Packard Company	    - 5 -	  Formatted:  August 2, 2006






 elstat(1M)							  elstat(1M)




	   State
		This indicates the state of the ELAN interface. One can set
		up a Backup ELAN, using the Secondary LECS High Availability
		option, while configuring an ELAN.  The value in this field
		indicates which ELAN is "Current" and which is the "Backup".
		If an ELAN interface is having Not-Operational Status this
		this will have "-".

		Possible Values : Current, Backup, "-".


	   LECS's ATM address
		The ATM address of the LAN Emulation Configuration Server
		(LECS) is used to obtain the configuration parameters for
		this ELAN.  This field also indicates how the LECS address
		has been obtained : From Network, Manual entry, or is it the
		Well-Known LECS Address.


	   Configuration Direct VCC
		The VPI,VCI of the Connection to the LECS.  It is quite
		likely that this would be shown as -,- meaning there is no
		connection to the LECS.	 This is because, the LECS
		connection is closed, after configuration is obtained from
		the LECS.


	   LES's ATM Address
		The ATM address of the LAN Emulation Server (LES) is used to
		establish the Control Direct VCC. This is obtained in the
		Configuration phase. This address MUST be known before the
		Join phase starts.


	   Control Direct VCC
		The VPI,VCI of the Control Direct Connection.  This is the
		P2P (point-to-point) connection established by the LEC to
		the LES.


	   Control Distribute VCC
		The VPI,VCI of the Control Distribute Connection.  This is
		the P2MP (point-to-multipoint) connection established by the
		LES to LEC.


	   BUS's ATM Address
		This is the ATM address of the Broadcast and Unknown Server
		(BUS).





 Hewlett-Packard Company	    - 6 -	  Formatted:  August 2, 2006






 elstat(1M)							  elstat(1M)




	   Multicast Send VCC
		The VPI,VCI of the Multicast Send Connection.  This is the
		P2P connection established by LEC to BUS.


	   Multicast Forward VCC
		The VPI,VCI of the Multicast Forward Connection.  This is
		the P2MP connection established by BUS to LEC.


	   Maximum Data Frame Size
		The configured maximum AAL5 SDU size of a data frame that
		the LEC wishes to send or receive. This is the AAL5 SDU size
		- 12 for LLC-multiplexed VCCs.


	   LEC Control Timeout
		Timeout period in seconds used for timing out most
		request/response control frame interaction.  Control time
		out consists of an initial time-out and a retry multiplier
		(or logarithmic back-off base).


	   Vcc Timeout Period
		A LEC should release any Data Direct VCC that has not been
		used to transmit or receive any data frames for the length
		of the VCC Timeout Period.  This is not used for any SVC
		signalled with the LLC Multiplexed BLLI value.


	   Maximum Retry Count
		A LEC MUST not return a LE_ARP_REQUEST for a given frame's
		LAN Destination more than Maximum Retry Count times, after
		the first LE_ARP_REQUEST for that same frame's LAN
		Destination.


	   Aging Time
		The maximum time that a LEC will maintain a unicast LAN
		Destination in its LE_ARP cache in the absence of a
		verification of that relationship.



	   Expected Arp Response Time
		The maximum time that the LEC expects a
		LE_ARP_REQUEST/LE_ARP_RESPONSE cycle to take.  Used for
		retries and verifies.






 Hewlett-Packard Company	    - 7 -	  Formatted:  August 2, 2006






 elstat(1M)							  elstat(1M)




	   Flush TimeOut
		The maximum time a LEC waits to receive an LE_FLUSH_RESPONSE
		after the LE_FLUSH_REQUEST has been sent before taking
		recovery action.


	   Maximum Unknown Frame Count
		Value: Minimum=1, Default=10, Maximum=20.  See Maximum
		Unknown Frame Time below.


	   Maximum Unknown Frame Time
		Within the period of time defined by the Maximum Unknown
		Frame Time, a LEC will send no more than Maximum Unknown
		Frame Count frames to the BUS for a given unicast or
		multicast LAN destination without initiating the address
		resolution protocol to resolve that LAN Destination.


	   Connection Complete Timer
		Optional.  In Connection Establishment, this is the time
		period in which data or a READY_IND message is expected from
		a Calling Party.


	   LEC Initial Control Timeout
		Value: Minimum=1 second, Default=5 seconds, Maximum=10
		seconds.  Also see LEC Control Timeout above.



	   LEC Control Timeout Multiplier
		Value: Minimum=2, Default=2, Maximum=5.	 Also see LEC
		Control Timeout above.



	   LEC V2 Max Unknown Frame Count
		Same as Maximum Unknown Frame Count parameter above, but for
		LANE Version 2.0.



	   LEC Config Local Segment ID
		The configured value of the Local Segment ID variable.



	   LEC Config V2 Capable
		If set, the LEC MUST exhibit LANE v2 behavior where it
		differs in its requirements from LANE v1 behaviour.  If



 Hewlett-Packard Company	    - 8 -	  Formatted:  August 2, 2006






 elstat(1M)							  elstat(1M)




		clear, the LEC MUST LANE v1 behaviour in these cases.



	   LEC Config Selective Multicast
		This is the configured value, which indicates if this LEC is
		configured to register to receive specific multicast
		destination MAC addresses.  MUST NOT be set if "LEC Config
		V2 Capable" flag is clear.



	   LEC Forward Disconnect Timeout
		If the LEC detects that the BUS has had no Multicast Forward
		VCCs to the LEC for time Forward Disconnect Time-out, the
		LEC MUST disconnect from the BUS and try to re-establish a
		new connection.



	   LEC Min Reconfigure Delay
		The minimum time that a LEC must wait before retrying
		configuration.



	   LEC Max Reconfigure Delay
		The maximum time that a LEC must wait before retrying
		configuration.



	   LEC Max Bus Connect Retries
		The maximum number of attempts that a LEC can try to
		establish the Default Multicast Send VCC before returning to
		the configuration procedure.



	   LEC Token Ring Explorer Frame Excluded
		This indicates whether or not the LEC wishes to receive
		token ring explorer frames other than those directed to one
		of its registered MAC addresses.  Normally, only bridges
		need to receive such explorer frames.  This parameter
		applies only to token-ring ELANs.



	   LEC Preferred LES Addr
		The ATM address of the preffered LE Server.  This variable
		is set during the Configuration phase by copying the



 Hewlett-Packard Company	    - 9 -	  Formatted:  August 2, 2006
