問題文
An operator wires a file server straight into an access switch and tells Junos that this particular link can never be part of a spanning tree, so the port starts passing frames at once instead of waiting out any timer. The operator wants the name of the role Junos assigns there. On an 802.1w trunk elsewhere, a designated port first offers to become the upstream side and then waits for the downstream port to reply before it will pass traffic. Which pair names the role and the reply?
