Now that they have got that out of the way, maybe they can agree on the damn VLAN IEEE 802.3u(?...the one for fast ethernet) standard. I had a LONG post written up on this some months ago, but decided to hold back (Don't want to piss off the industry<G>). What it came down to was that all members agree on MOST parts of it...except for one very vital part. The way the IEEE 802.3d Spanning Tree is to be implemented. This protocol is used to locate bridge loops by eliminating them...or "blocking" specific interfaces from passing traffic, allowing others to "forward". Anyway one asshole vendor decided that instead of making each VLAN (each virtual segment) an independent Spanning Tree domain, they wanted the spanning tree domain to be hardward dependent....that is to say a root bridge (switch) would be determined for ALL VLANS depending on the physical topology, and not the virtual topology (the V in Vlan stands for virtual). That makes it simple for them, Spanning tree only converges once for all VLANs in the network, regardless of the logical VLAN structure. This sucks! The only reason they would do that is the're CPUs can't handle the extra load of a true mult-spanning tree convergence, and it pukes. So they won't sign up. Everyone else will, but they won't. So each vendors VLANs still wont talk to other vendors. Want to know who the vendor is? I'll give you a hint. The first character starts with a "3". Still snowing out...and rt 66 is packed...so it looks like I wont be leaving for work on time. Oh well. <G> It'll come out of my paycheck. Pissed off, Paul.
