Description Note:
■ Make sure the holding time (HT) of the information ISH packets carry is at least
three times to the interval to send ISH packets (CT). Otherwise, you are prompted
with configuration error messages.
■ HT value must be at least three times of that of CT. So, with CT larger than 60, if
you try to revert to the default HT (180) by executing the
undo timer holding
command, you are prompted with an error message and the operation stops. You
can execute the
undo timer holding command to revert to the default HT
successfully only when CT is less than or equal to 60.
