The MXL switches will support Virtual Link Trunking (VLT) later this year, which will solve this issue.
Hi guys, If uptime is the most important thing, would you trunk or stack MXL switches? I like the simplified management, ability to load balance over multiple links but I'm concerned with the uptime during firmware upgrades (5-10 minutes?) and the possibility of total outage if the stack breaks. On the other hand Force10 might be more stacking capable than eg. 6224 switches, which I have had a lot of stacking problems with. Forgive me if this is the wrong place to ask, but I could not find a Force10 forum? :-) Thanks RegardKristoffer
