Asif,
It's the order of operation. In order for you to have the desired result,
this operation must be followed.
1. Select all the ports of the port channel - interface range command
2. shut all the interfaces
3. Apply the channel-group command
4. Apply the trunk mode and the encapsulation
5. re-enable the interfaces - no shut
Eg:
interface range f0/13-15
shut
channel-group 13 mode on
switchport trunk encapsulation dot1q
switchport mode on
no shut
I always apply the configuration to the port-channel interface before
applying to the physical interfaces to avoid all the issues with order of
operations.
HTH,
Shine

Hi Gopal,
I would like to thank you for your reply, but when see the configuration
of the switch under port-channel 25 ; it doesnt shows me the two statements
( switchport trunk encapsulation dot1q / switchport mode trunk )
Interface port-channel 25 ( its up )
Sh EtherChannel shows output as ( SD )
