Ping
Interval: Sets
the normal interval between polling nodes.
Fast Interval:
When retrying to ping a node, the interval between pings
is reduced to the Fast Interval. For accurate timing the
fast interval value should be a factor of the normal
interval value.
Down Retries:
How many times a failed ping is retried before a change
of state is logged.
Up Retries: How
many times a ping is retried to confirm a node is up.
Timeout: How
long each ping waits before deciding no reply was
received.
Flash Time: When a
node status change is confirmed, the corresponding table
cell and the indicator in Network Notead flash for the
number of seconds set here.
