Hi Sagar,
Please try this and let me know if it works for you
Cisco:.
interface <interface id>
switchport trunk encapsulation dot1q
switchport trunk allowed vlan <vlanid>
switchport mode trunk
channel-protocol lacp
channel-group 3<port-channel id> mode active
no shutdown
interface Port-channel<port-channel id>
switchport trunk encapsulation dot1q
switchport trunk allowed vlan <vlanid>
switchport mode trunk
no shut
If you use "on" Etherchannel, it is created only when another interface group in Etherchannel "on" mode
