AnonDog, I was thinking of asking a developer to modify the BPDU generation code in switch to use either wireless packet error threshold or total link failure. SixNetIO provides OEM kit with SDK but I did not ask them about licensing cost yet. »www.sixnetio.com/html_files/oems···ches.htm I have to order some kevlar-protected CAT5 to see if rodents can chew through it.

You don't need to modify firmware on systems which can run LEAF. »leaf.sourceforge.net/wisp-dist/ I've used it and it works pretty well. As a matter of fact I flashed an old Raylink CPE with it (Remember Lonnie's stuff?) and stuck a Linksys card in it and ran it as an AP for the neighbors for over a year. Worked reliably. I think that STP is probably embedded in that code already. I have not looked at it in a couple of years but the entire LEAF system can be downloaded and used to do some pretty nice firmware development.

Yes. Our office has a few 3-port Linux boxes that did STP/RSTP/RPR etc. I recalled posting on a similar thread from last year: »Re: WAN ring via wireless Bridging using STP?? But while RPR gear would be excellent to build wireless rings and broken rings (daisy chain), they are still rare and expensive. Rapid spanning tree (RSTP IEEE 802.1D/w) seems to be the next best thing and SixNetIO switch claims amazing 50 millisecond failover. STP will take a minute to failover.

AnonDOG @kaballero.com	said by lutful : STP will take a minute to failover. Agreed and a minute is an eternity ... unless it is compared to an hour long drive to a remote site. If all switches honored RSTP, I'd say yes that is what we need right now, but lots of guys have to buy older switches from E-Bay and they don't support RSTP. If it (RSTP) is backward compatible (with STP) then absolutely go for it over STP. If it isn't work out a migration path and deliver STP capable devices until RSTP capable switches are under $100.00 on E-Bay. You are certainly correct, a 50 ms fail over is desirable over a 60 second fail over but a few dropped VoIP calls are usually survivable. I think those hardened switches at SixNetIO look pretty cool. They are a bit pricey but a hard switch is good to find... They look like you get what you pay for with that company.
