Im about to pull my hair out. I have two 3500xl switches running IOS c3500xl-c3h2s-mz.120.5.bin and both switches have deemed themselves the root. On one switch I lowered the priority,max age,hello, and forward and left the other one at its defaults. Root guard is turned off on both switches, running in transparent mode, no bpduguard. No portfast on the ports that are linked to each other, duplex and speed are the same for both. No other Vlans, just the native vlan1. I am overlooking something and cannot figure it out. Any ideas?
If it works with a computer or router then the cross over cable you should be using between the switches is no good if you are not getting a link . With a computer or router you use a straight thru versus a crossover. Your first post was confusing because you did not mention that you had no link light , obviously if you have no link they will both think they are the root for the vlan.
