The time period during which link state transitions accrue
toward the threshold count etsysLinkFlapIntfCountThreshold.
Setting etsysLinkFlapIntfTimeInterval such that the
ratio of etsysLinkFlapIntfCountThreshold to
etsysLinkFlapIntfTimeInterval would become greater than
etsysLinkFlapSystemLinkFlapMaximum will result in the set
operation failing with an inconsistentValue error.
Note that one special value, 0 (zero) of the
etsysLinkFlapIntfTimeInterval is used to specify that
etsysLinkFlapIntfTimeInterval is unbounded.
Maintaining the value of this object across agent reboots
is REQUIRED
