-- Name 	: ATSWTCH2.MIB
-- Version	: 1.8 for 802.1q Compliant Fenix switch.
-- Description 	: Private MIB for ATI Next Generation atswitch Switch (AT37XX).
-- 		: This MIB will be used in Windows and UNIX Environment.

-- History :
--	 *   08-13-97 - Create.
--       *   01-11-98 Changed the MIB object PortCount to return correct number.
--       *   01-28-98  Changed the PvVlanName to PvVlanId. Also some changes
--       *             in the PortStatus, etc.
--	 *   02-04-98 Removed TpFdbAge as the ASIC doesn't support the Age.
--       *   02-05-98 Added atswitchIPAddressStatus
--       *   02-18-98 Changed the PortNum and MonId to 27 from 25 and 16 respct.
--       *   03-03-98 Changed the PortNum and MonId and wherever the Ids were
--       *            hardcoded. Also changed the description here and there.
--       *   04-28-98 Added the MDAType, added more state for atswitchPortState,
--	    *   05-21-98 Added Objects concerened with 8124XL.
--	    *   05-21-98 Added FlowControl only for 8124XL and changed PortSpeed
--				  to read-write.
--	    *   06-01-98 Added 8124XL product Id.	
--	 *	   09-14-98 Changed Other to 10 and added 3714XL.    
--	*	09-29-98 added FlowControl as a device Config Param.
--	*	10-02-98 Changed the PvVlanId Integer back to PvVlanName string.
--	*	10-01-98 Added Port2Vlan Table to be read-write and also
--	*		 Added Implicit Vlans for each port Entry.
--	*	10-05-98 Added atswitchBeVlanTagId and atswitchBeVlanOuputPorts and 
--	*		    changed the atswitchBeVlanStatus decsription to be more of a
--	*		    Row Status Object. 
--      *        09-17-98 Added the security feature. ( added later)
--	*	 12-10-98 Aded Trunk Group and added StaticMACVlan suppport.
--	* Trying to merge fenix and Buffalo to make it a single MIB.

          -- Protocol to uniquely identify a bridge.  Its first two
          -- octets (in network byte order) contain a priority
          -- value and its last 6 octets contain the MAC address
          -- used to refer to a bridge in a unique fashion
          -- (typically, the numerically smallest MAC address
          -- of all ports on the bridge).

          -- Several objects in this MIB module represent values of
          -- timers used by the Spanning Tree Protocol.  In this
          -- MIB, these timers have values in units of hundreths of
          -- a second (i.e. 1/100 secs).
          -- These timers, when stored in a Spanning Tree Protocol's
          -- BPDU, are in units of 1/256 seconds.  Note, however,
          -- that 802.1D-1990 specifies a settable granularity of
          -- no more than 1 second for these timers.  To avoid
          -- ambiguity, a data type is defined here as a textual
          -- convention and all representation of these timers
          -- in this MIB module are defined using this data type.  An
          -- algorithm is also defined for converting between the
          -- different units, to ensure a timer's value is not
          -- distorted by multiple conversions.
          -- The data type is:

          Timeout ::= INTEGER -- a STP timer in units of 1/100 seconds

          -- To convert a Timeout value into a value in units of
          -- 1/256 seconds, the following algorithm should be used:
          --
          --      b  = floor( (n * 256) / 100)
          --
          -- where:
          --      floor   =  quotient [ignore remainder]
          --      n is the value in 1/100 second units
          --      b is the value in 1/256 second units
          --
          -- To convert the value from 1/256 second units back to
          -- 1/100 seconds, the following algorithm should be used:
          --
          --      n = ceiling( (b * 100) / 256)
          --
          -- where:
          --      ceiling =  quotient [if remainder is 0], or
          --                 quotient + 1 [if remainder is non-zero]
          --      n is the value in 1/100 second units
          --      b is the value in 1/256 second units
          --
          -- Note: it is important that the arithmetic operations are
          -- done in the order specified (i.e., multiply first, divide
          -- second).
