Dear all

Please let me know the difference of following two
configurations.

ex1) Etherchannel
interface Port-channel1
 switchport trunk encapsulation dot1q
 switchport mode access
 no ip address
!
interface FastEthernet0/1
 switchport trunk encapsulation dot1q
 switchport mode access
 no ip address
 duplex full
 speed 100
 channel-group 1 mode active
 channel-protocol lacp
 lacp port-priority 1
!
interface FastEthernet0/2
 switchport trunk encapsulation dot1q
 switchport mode access
 no ip address
 duplex full
 speed 100
 channel-group 1 mode active
 channel-protocol lacp
 lacp port-priority 1
!

ex2) Trunk
interface FastEthernet0/1
 switchport trunk encapsulation dot1q
 switchport mode trunk
 no ip address
 duplex full
 speed 100
!
interface FastEthernet0/2
 switchport trunk encapsulation dot1q
 switchport mode trunk
 no ip address
 duplex full
 speed 100
!

The ex1) works as Etherchannel.
How about ex2) ? Does it work like ex1) ?
For example,if fast0/1 trunk down,does fast0/2 trunk work
as backup.And does fast0/1 and fast0/2 work with bundle ?
Please let me know the difference in detail.

regards.
