        "Describes the current operational state of the device.
         Operational status may be expressed as one of the following:

         enabled(1) - indicates that the device in online and 
         fully functional.

         initializing(2) - indicates that the device is initializing.  
         Devices enter the initializing state when powered on, or 
         when reset.

         failure(3) - indicates that the device's self-test has 
         detected a fault.  The device is functionally offline, 
         and may or may not be powered.

         nonFatalFailure(4) - indicates that the device's self-test
         has detected a non-fatal fault.  The operates are less than
         a fully functional level in the presence of non-fatal errors.

         loading(5) - indicates that the device is attempting to load.

         disabled(6) - indicates that the device has been disabled.
         The device must still be able to respond to management 
         messages.

         needProgramLoad(7) - indicates that the device is waiting
         to be loaded.

         testing(8) - indicates that the device in performing some
         form of diagnostic testing.

         lowPowerMode(9) - indicates that the device is only partially
         powered.  Some classes of device wait in this mode until the
         Hub Manager to grant additional power.

         Modules may only be managed via an NMS when they are in the 
         online and/or disabled states.

         Not all components implement all state of this object.  
         For example, if a component can not report 'failure', then
         it doesn't.  The enabled and disabled states are supported
         by all components."

    ACCESS  read-write
    STATUS  mandatory
    DESCRIPTION
        "enabled(1) - setting this object to enabled causes the 
         device to begin it's power up sequence and attempt to 
         enter its operational state.  If the value of this object
         was disabled, then the non-volatile value of this object
         is changed to enabled.  As part of the power up sequence, 
         the device's management parameters may or may not be 
         reset.  (In other words, the device may go through the 
         equivalent of a reset or before returning to the online state.  
         If the device is capable of going directly from the disabled
         state to the enabled state without resetting any of its
         management parameters, then it may do so.  Such action is 
         product specific.)

         disabled(2) - setting this object to offline causes the 
         device to cease network activity and enter a quiescent 
         state.  A disabled device must still be able to respond 
         to management messages.  

         The value enable(1) or disable(2) shall be stored
         in non-volatile memory for the initial reset value
         of this variable.  The factory default NV value is enable(1).

         reset(3) - setting this object to this state resets the 
         module, including its volatile managed objects.  Resetting 
         may involve running the devices self-test diagnostic.  
         If diagnostics fail, this object will remain in the reset 
         state and failure status will be reflected elsewhere in the
         mib.  If diagnostics pass, then the device will automatically 
         return to the enabled state.  After reset, this object shall
         assume the non-volatile value of enable(1) or disable(2).
         (So, if you reset a disabled module, the device will reset
         and come back up still in the disabled state.)

         restoreToDefaults(4) - setting this object to this state 
         restores all of its non-volatile parameters to their 
         factory default state and resets the module (see reset(3)).

         Note:  The default value of this object is, or course, enabled.

         Note:  Some devices may not send a getResponse to a PDU
         which commands the device to reset.  Setting this object
         to reset, restoreToDefaults, or enable may cause the device
         to reset."

    DESCRIPTION
        "The pcomLedProgram string is a sequence of instructions for
         the LED state.   The LED constantly repeats the program.

         Each LED state is represented by a two octet sequence where
         the value of the first octet of the pair indicates the color
         of the LED, and the value of the seconds octet of the pair
         indicates the duration in which that color will be present.

         +----------+----------+  --/ /--  +----------+----------+  
         |   Color  | Duration |           |   Color  | Duration |
         +----------+----------+  --/ /--  +----------+----------+  

         The 'color' octet may have one of the following values:

            0 - off
            1 - other
            2 - red
            3 - yellow
            4 - green
            5 - blue
            6 - red-blinking
            7 - yellow-blinking
            8 - blue-blinking
            9 - green-blinking

         The value 'off' indicates that the led is off.

         The value 'other' indicates a color not covered by any others
         in the list.

         The value of the second octet in each pair indicates the
         duration in which that color will be present.  A value
         of zero indicates that the LED is off.  A value of 0xff
         indicates that the LED is always on.  Values in between
         0 and 0xff indicate the duration in 10 ms ticks.

         A zero length string may be returned if the LED is
         'not present'.  This indicates that the LED is 
         currently not visible.  (This is provided for modules 
         which may attach to different chassis, i.e. an 8-slot chassis 
         or a single-slot chassis, in which a different LEDs may be 
         visible.  For example, say an extra three LEDs are visible 
         when the device is inserted in a single-slot chassis.  When 
         the device is removed from the single slot chassis and   
         inserted into the 8-slot chassis, these three LEDs may not
         be visible.  Therefore, a zero length string may be returned
         to indicate that these three LEDs are not present.)

         Activity LEDs are a special case.  Activity LEDs are defined
         as LEDs which blink whenever data is received on the line.
         They are typically on solid under heavy activity.  Since these
         LEDs can change rapidly, the following rules apply:

           o  The initial state of activity LEDs is off.
           o  If the line shows activity any time in a 10 second
              period, then the LED is shown as on.
           o  If the line shown inactivity any time in a 10 second
              period, then the LED is shown as off.

         Example:  Consider a 4-bank, 12-port repeater:

         Bank:     Ports:
         ----      -----
         Bank A:   A1, A2, A3

         P3:     Port Status 3A/B/C/D            9

         Assume the ports of this repeater are in the following states:

         Port:   State:
         ----    -----

--  SNMP Authentication Database.
--
--  The Simple  Network  Management  Protocol  (SNMP)  employs  a  "trivial"
--  authentication  scheme  based on "community names".  Community names are
--  textual strings which represent access to a set of objects with a set of
--  access rights.
--  
--  The SNMP Authentication Group  contains  objects  which  provide  access
--  rights  for  three communities:  read-only, read-write, and traps.  Each
--  of the three communities  contain  a  community  string  object,  and  a
--  UserTable.
--  
--  The community string provides the name of the community.  All  community
--  strings  are  initially  "public".   The default community string may be
--  changes to provide additional security.   For  example,  the  read-write
--  community  may  be  changed from "public" to "secret".  This only allows
--  read-write access to users who know the  "secret"  read-write  community
--  string.
--  
--  The UserTable is a table of  authorized  users  of  the  community.   By
--  default,  all  users  (who known the community string) are authorized to
--  use the community.  Each communities UserTable  contains  three  object:
--  UserAddr, UserMask, and UserStatus.
--  
--  UserAddr is the IP  address  of  an  authorized  user,  or  a  group  of
--  authorized  users.   Initially,  all  users are allowed access.  Writing
--  16.21.16.128 to an entry  of  the  read-only  UserTable  prohibits  read
--  access from any host but 16.21.16.128.
--  
--  UserMask is used to provide 'wildcard' authorized users.  This  mask  is
--  applied  to  the  incoming  IpAddress and the value of the corresponding
--  UserAddr.  If the resulting incoming IpAddress and _UserAddr match,  the
--  message   is   considered   authorized.    (For   example,  UserAddr  of
--  16.21.16.128 and UserMask of 0xffffff00 allows users from 16.21.16.0  to
--  16.21.16.255 to be authorized on the community.)
--  
--  UserStatus is used to create and delete entries.  Entries are created by
--  setting  UserAddress.   Entries  are  deleted  by  setting UserStatus to
--  invalid(2).  Invalid entries are removed from the UserTable.
--  
--  All trap, read-only, and read-write  community string are  non-volatile.
--  All UserTable information is also non-volatile.

--
--  The errLogTable is a ring.  If a maximum of 8 entries are supported

--  overwrites the oldest entry, entry 1, such that the table contains
