3. to configure standby links you need to configure them for priority values higher than the priority values of the active links. In PAgP this feature is not applicable as far as I know.
4. In PAgP you cannot influence the selection of a master.
5. yes, but the trunk configurations of all links must be the same: speed, duplex, native vlan, allowed vlans, trunking mode and encapsulation, spanning-tree settings.
6. In silent mode the channel will be set up even if the other side of the channel is "silent", i.e does not reply to the PAgp packets sent by one side.
In non-silent mode, the initiator of the PAgP packets expects that the other side be "non-silent", i.e will reply for the requests.
This feature is interesting, because it can be used to detect unidirectional link failures. If the other side does not reply in "non-silent" mode, this side will shut down the link and layer2 loops cannot form.
A good book on Etherchannel technology is :
