Note that when you enable PAgP on a link where Spanning Tree is active, Spanning Tree takes about 18 more seconds to converge. This is true because PAgP takes about 18 seconds to negotiate a link. The link negotiation must be completed before Spanning Tree can start its convergence algorithm.
If you change an attribute on one of the EtherChannel segments, you must make the same change on all of the segments for the change to be effective. All ports must be configured identically.
