i understand the meaning of the message timer, but what ist the use of the time out interval? On the cisco webpage i found: "When UDLD neighbors are established, the configured message interval is sent and the timeout interval for that peer is calculated to be (3 * message_interval)."
But on my switch the output shows 2 kind of timers:
Port enable administrative configuration setting: Enabled / in aggressive mode
Port enable operational state: Enabled / in aggressive mode
Current bidirectional state: Bidirectional
Current operational state: Advertisement - Single neighbor detected
Message interval: 15
Time out interval: 5
Expiration time: 42
Cache Device index: 1
Current neighbor state: Bidirectional
So, what is the difference between Message Interval and Time out interval, can somebody explain?
