We intentionally didn't make an explicit provision for that, because it's not at all safe to do. If bridges are interconnected, it's possible for loops to form, and loops in bridging are quite toxic; they take the whole network down. They're much worse than loops at layer 3. You should only be seeing the "error-disable" state if STP was disabled, and BPDU guarding brought the port down. If things are as you're describing above (and it's not a typo), then it sounds to me like a bug of some sort. It's possible that switching the protection mode (-P) to "trill" will give you what you want, but it's not clear to me. It'd be good if you could describe what it is you're trying to do. Why do you want to have STP disabled when interconnecting bridges? How do you know that nobody will ever accidentally plug the wrong wire into the wrong port and destroy your network? -- James Carlson 42.703N 71.076W <[email protected]> _______________________________________________ networking-discuss mailing list [email protected]
