Spanning tree root election looks at priority first, with the lowest mac
address winning the tie breaker. If it's an IOS-based switch, you can
change the mac address on the interface so you can lose all elections. That
I think would guarantee never becoming a root. That's not an option on a
CatOS switch though.

I've been going through the threads on spanning tree and one thread that
never had a consensus was how to ensure a switch would "never" become root.
There is not a text I have found that addresses this. From what I can tell,
one option is to turn off spanning tree completely, the other to set
priority to 65535. Neither sounds appropriate to me.
