Netwatch explanation please.

[briane]

Hi,

When setting up a netwatch, the two variables on the Host Tab “Interval” and Timeout" seem simple and first…and then I start thinking about this in more detail, and it becomes less clear.

If the Interval is set at 2s and timeout at 10s, will this fire pings at 2,4,6 and 8 seconds, and then at 10s, if no response is received on ping 1 (sent at 2s), trigger the Down response? And if Ping 2 responds within the 10 seconds after being sent, does this then trigger the Up response, even though the down response is already in motion?

Should the interval always be less than timeout?

How exactly does the netwatch function with respect to the interval, timeout and UP/DOWN responses?

Maybe I am “over thinking” this issue…

Regards
Brian

Brian, the interval should always be more than the timeout. So say you set your interval for every thirty seconds and the timeout for 5s, the router will check to see if the IP is reachable every 30 seconds by pinging it. If after 5 seconds no response if received, the netwatch script triggers the ‘down’ script.

Make sense?
