Hello Guys ,
I am planning to impliment 2 cross stack etherchannel between 2 2960 <> 3 Stacked 3750
Already there is a etherchannel 1 between 2 2960 .
I am afraid if I connect 3750 stack with these 2960 with etherchannel 2 and 3 there will be STP loop , your thought ?
Alos I Hvae put etherchannel configration on 3750 is below but dot1q i cant find in 2960 so is there diferent etherchannel config i should try
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 2 mode on
