I have 2 cisco core switches and 3 access layer switches. I will be using 6 gigabit ports from the core switch to create 3 port channels , one for every access layer switch.
My 3 questions are :
1. the first two ports on the core will form port channel group 1 , the other two port channel goup 2 and the next 2 , port channel group 3 , right ? Each group will have a different id number..
2. where will i put the command switch port trunk allow vlan all... to the core or on the access switches , or on both ?
3. On the access layer switch , when i create the port group what id will i be using ? I would assume it has to match the id on the core switch , right ?
