<p>I created an EtherChannel group 1. I can see both interfaces with the "show etherchannel 1 summary" but both interfaces appear with a (D) instead of (P). I have the same configuration on both switches. I am using ports Fa 0/1 and 0/8. Any hint to why they are not in (P)?</p>
if you wish to test failover with your etherchannel you can do the following which will maybe show you visually the changes that happen.
Switch A port 1 X Switch B Port 1
Switch A port 8 - Switch B Port 8
manually shut down interface FA0/1 on Switch A which will bring down the interfaces ur seeing with (Pd) - this will move the default channel to the second link you have in your etherchannel. issue the show etherchannel summary command .. bring the first link buack up be re-enabling FA0/1 on switch A and the default should still be listed on the second link.
Hope this helps a little .. perhaps reading up on etherchannel will give u a greater understanding as well as to how this works and the benefits.
