"Desirable" is preferable if you monitor the state of this ether
channel. A syslog message will be generated when it is UP or DOWN. When
Ether channel configured with ON, it will be in UP state always
regardless the other end.

Gary,
Not to be nitpicky, but why use 'desirable' instead of 'on' when doing
the channel-group?
I know that Cisco loves options, and they love to make things 'detect'
other things, but I've always been a big fan of making things concrete
when possible, so I would use the 'channel-group 1 mode on'. I mean,
let's face it, either you want an etherchannel or you don't. I treat
trunks the same way (as you did in your sample config) where I force
both ends as far as encapsulation and mode. (I also for EVERY
switchport that's NOT a trunk by using 'switchport mode access'.....
Drives my co-workers crazy)
Just curious.
Mike W.

Fan,
This should work:
interface Port-channel1
switchport trunk encapsulation dot1q
switchport mode trunk
no ip address
interface FastEthernet0/22
switchport trunk encapsulation dot1q
switchport mode trunk
no ip address
channel-group 1 mode desirable
!
interface FastEthernet0/23
switchport trunk encapsulation dot1q
switchport mode trunk
no ip address
channel-group 1 mode desirable
Regards,
Gary Lileikis
