For dedicated ports, oversubscription ratio restrictions do not apply to the shared pool in port groups. So
if oversubscription ratio restrictions are disabled, and you have configured three 4-Gbps dedicated ports
in one port group, then you can configure all other ports in the same port group to operate at a shared
rate of 4 Gbps.
In the following example, a 48-port module has a group of six ports, four dedicated ports are operating
at 8 Gbps, and the two shared ports are also operating at 8 Gbps:
