        DESCRIPTION
         "This document describes a management information base for
          the IS-IS Routing protocol, as described in ISO 10589,
          when it is used to construct routing tables for IP networks,
          as described in RFC 1195.

          This memo defines an experimental portion of the Management
          Information Base (MIB) for use with network management
          protocols in the Internet community.

          This memo is based on a 1994 IETF draft by Chris Gunner.
          This version has been modified to include MIB-II syntax, to
          exclude portions of the protocol that are not relevant to IP,
          and to add management support for current practice."

-- Behavior Definitions

-- ResettingTimer behavior definition
-- "This object specifies the interval between certain events in
-- the operation of the protocol state machine. If the value of
-- this object is set to a new value while the protocol state
-- machine is in operation, the implementation shall take the
-- necessary steps to ensure that for any time interval which
-- was in progress when the value of the corresponding object
-- was changed, the next expiration of that interval takes place
-- the specified time after the original start of that interval,
-- or immediately, whichever is later. The precision with which
-- this time shall be implemented shall be the same as that
-- associated with the basic operation of the timer object."

-- ReplaceOnlyWhileDisabled behavior definition
-- "This object may not be modified while the corresponding
-- table row's variable of type AdminState is in state on."

-- OperationalState behavior definition
-- "This object controls the enabling and disabling of the
-- corresponding table row. Setting this object to the value
-- off has the effect of disabling the corresponding row.
-- Setting this object to the value on has the effect of
-- enabling the corresponding row. Setting the value of this
-- object to the same value as its current value has no effect.
-- If the table entry also contains an object controlling the
-- row status then the object following the operationalState
-- behavior shall not be set to on when the object following
-- the Row Status behavior has value off. An attempt to do
-- so is rejected."
