Specifies the action to be taken on an interface
when the increase in an error counter on that
interface between two consecutive sampling
exceeds the corresponding clemThresholdHigh for
consecutive number of times as specified by
clemSamplingTimes.
errdisable -- the interface is disabled by forcing
its link down.
failover -- when the interface is a member of a channel
and it is the only operational member in
the channel, then no operation will be taken.
Otherwise, disable the interface by forcing
its link down, i.e., errdisable the interface.
