Is this correct? Is there something else to it?
The command "frame-relay end-to-end keepalive event-window" set total number
of errors that can be recorded: the bin
When a keepalive is missed the bin is incremented by one and then when the
event-window has accumlated to a certain value determined by the "frame-relay
end-to-end keepalive error-threshold:" the interface goes down.
Lets suppose that the bin is set for 32 errors (the max for event-window),
and the interface goes down after 3 errors (the error-threshold) .
If no keepalive is received, after 3 missed the interface goes down. Lets say
there are no keepalives for another 17 keepalive cycles, then thing start
working again.
The "frame-relay end-to-end keepalive success-events" will determine how many
successive keepalive to put the interface up.
(As I understand it, the event-window would be reset to zero after that)
To summurize:
"frame-relay end-to-end keepalive success-events" the number of consecutive
success events required to change the keepalive state from down to up.
"frame-relay end-to-end keepalive error-threshold: Number of errors in the
event window before keepalive status goes from up to down."
"frame-relay keepalive event-window" : the bin recording the errors - There
are no bin recording consecutive successes !
