Yes, you need to be on 1.3 to support the 1GB uplink option. With firmware 1.3 the first 8 fixed ports are the only ones that support 1GB.

Using 1 gb uplink can lead to unpredicatable behavior. If load balancing on say esx is sending traffic between two hosts on the same fi it will be 10gb. If f it goes out say vnic1 on one host and back in vnic0 on the other it has to go via 1gb. Tis can lead to sometimes traffic between two servers is 10gb sometimes it's 1gb.
