-- Name         : ATIL2.MIB
-- Version      : 2.3
-- Description  : Private MIB for ATI Gigabit Uplink and 10/100M Switches.
--              : This MIB will be used in Windows and UNIX Environment.

-- History :
--       *   04-13-99 - Created.
--       *   04-03-02 (Praveen) - Renamed the MIB from fstswtch-mib to atil2-mib
--       *   04-17-02 (Praveen) - Added atiL2DeviceNumber. Extended atiL2deviceProductType 
--                                with values for AT-8326GB, AT-9410GB and AT-8350GB
--       *   04-18-02 (Praveen) - Added product OID entry for AT-8316F
--       *   04-26-02 (Praveen) - Changed atiL2DevicePortSpeed from read-write to read-only
--       *   08-23-02 (Praveen) - Added a new product specific group atiL2QOSConfigGroup, 
--                                applicable only to AT-8326GB, AT-9410GB and AT-8350GB.
--                                Changed range of atiL2DevicePortSTPCost from 0..65535 to
--                                1..65535

                                                  -- Identifier as 
                                                  -- used in the
                                                  -- Spanning Tree
          -- 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).
