I need to connect two powerconnect M6220 to the existent lan infrastracture.
The two switch are configured in stack.
Which is the best way to uplink the new switch to the other two powerconnect 5548.
The old switch are not stacked, and linked among them with two 10GB Ethernet cable (one of the link is disabled).
I need to implement fault tolerant network, maybe i need to configure the spanning tree on the two 10 GB link.
Could I use Spanning tree to configure the uplink between the old and the new, too?
There is another better solution? there is another way to prevent network loop?
thanks, Francesco
