Ports can form an EtherChannel when they are in different PAgP modes as long as the modes are compatible. For example:
•https://www.cisco.com/i/templates/blank.gifA port in the desirable mode can form an EtherChannel with another port that is in the desirable or auto mode.
•https://www.cisco.com/i/templates/blank.gifA port in the auto mode can form an EtherChannel with another port that is in the desirable mode.

Ports can form an EtherChannel when they are in different LACP modes as long as the modes are compatible. For example:
•https://www.cisco.com/i/templates/blank.gifA port in the active mode can form an EtherChannel with another port that is in the active or passive mode.
•https://www.cisco.com/i/templates/blank.gifA port in the passive mode cannot form an EtherChannel with another port that is also in the passive mode because neither port starts LACP negotiation.
