Shine,
Will there be issue if I dont have the commands under the port-channel??
I am curious to know this ... since I tested without the commands under
the port-channel and it works (since this trunks are between two
switches ; I am able to pass VLAN traffic between these switches)
_*SW1*_
interface range fa 0/1 -2
switchport trunk encapsulation dot1q
switchport mode trunk
chanel-group 25 mode on
Interface port-channel 25
_*SW2*_
interface range fa 0/1 -2
switchport trunk encapsulation dot1q
switchport mode trunk
chanel-group 25 mode on
Interface port-channel 25
