Hi Kabeer,Please check out

Hi Kabeer,

Please check out your configuration as I mentioned:

On both switches:

int range f0/0-1
switchport trunk encapsulation dot1q
switchport mode trunk
channel group 10 mo active (for Lacp)
no shut
exit

Some of the restrictions which should be match both sides:

1) Speed
2) Duplex
3) STP mode
4) Vlan membership (for access ports)
5) Native Vlan (for trunk link)
6) Allowed vlans (on trunks)
7) Trunking Encapsulation

The reason is the 3560

The reason is the 3560 supports both ISL and DOT1Q, hence you need to specify the same, 2960 does the latter only.

Post your EC configuration...
