Maximum Auto-Negotiation Time on Twisted-Pair Gigabit Ethernet?
Hello,
I need to know how much time the Auto-Negotiation process can take in 1000Base-T networks. I have already looked into the IEEE 802.3 standard, but there is no maximum period specified directly. Maybe I have missed somehting... I also have to admit that I didn't READ the whole thing 
In the 802.3u document, there is this "Link Test Fail state exit condition" of "autoneg_wait_timer expired and either RD = active or consecutive link test pulses = 3 min., 10 max". Since the link test pulses have a much shorter interval, this would mean that 1000 ms is the maximum.
But there are also other timers which sound like they may be somehow related to the maximum auto-negotiation time:
- autoneg_wait_timer 500 ms to 1000 ms
- break_link_timer 1200 ms to 1500 ms
- link_max_timer_done 5 ms to 7 ms
Any help would be appreciated!
Autoneg_wait_timer is a timer used to time the amount of time to wait before evaluating the number of link integrity test functions which have link_status=READY asserted. The autoneg_wait_timer preferably expires 500ms to 1,000 ms from the assertion of link_status=READY.
Break_link_timer determines the amount of time to wait in order to assure that the link partner enters a link fail state. This is a state in which the link partner recognizes that network communication on the link has been broken and autonegotiation must be initialized. This timer preferably expires 1,200 to 1,500 ms after being started.
So it looks like at least 1500 MS? great question.

The Talented Auto Navigation System
Today's auto navigation systems aren't just for the car, truck, or SUV. More and more manufacturers are discovering that offering drivers the option of taking their navigation systems off road is an incredible boon to sales. With this realization they are delivering on many levels previously unheard of. There are even GPS and navigation systems that are designed in order to assist in finding a great catch. Perfect for the fisherman in your life.
Seriously if you're looking for creative ways in which to justify the expenditure of an auto navigation system, perhaps the following activities and ideas can help:
1) Biking. Biking isn't limited to sidewalks and roadsides any more. People are becoming much more adventurous and demanding of their bicycle travel today and taking the tour off road. This means that there isn't always a clearly defined path to guide you to your destination or even to find your way back to civilization. A good GPS or auto navigation system can help you find your way back home no matter how far you've strayed.
2) Geo Cashing. This is a relatively new pass time activity that seems to be taking on a life of its own. For those who enjoy this activity I am sure you are well aware that it occasionally takes you well away from the ordinary beaten path. Not all of us are as observant as we should be while looking for something and discover all too late that we have no real clue as to how to get back to the point we began. You will use your GPS system for the purpose of geo caching, but if you purchase a minor upgrade you can also use it to guide you back to your point of origin should you find yourself lost in the woods.
3) Hunting. There is no rule anywhere that even remotely indicates a necessity for navigational skills in order to make an excellent hunter. In fact, I've known more than a few hunters who have a difficult time finding their way home some days. For these fellows and femmes, there is hope and a way to save face. Navigational assistance is a great way to discover where you are, where you've been, and get your where you want to go.
4) Boating. If you've ever been in the open sea I'm sure you'll understand what I am saying when I say it is very easy to become disoriented as to where you are headed. Now, those who are seasoned at navigation will tell you it's a piece of cake. I'm here to tell you that they must have learned it at their daddy's knee because I certainly tried to learn as an adult and it still seems completely Greek to me (of course, perhaps it is, I've heard that the Greeks are phenomenal sailors). Regardless, GPS and auto navigation systems can make your journey by sea a much safer experience while helping insure that you reach your destination, preferably without incident with any sandbars in the region.
By car, land, bike, and sea auto navigation systems have a great deal to offer the savvy consumer. Take the time to study the many options for GPS equipment and find the one that will suit the inner explorer in you. You will find it is well worth the investment if you use it often and use it well.
