You can change the port protocol at the Controller level. You can also specify whether the Ethernet ports are to be aggregated into a single link and the aggregation priority.
If you select the entire Controller, you can change the protocol supported by a slot. If the protocol is Ethernet, you can aggregate the ports into a single link.
If you select a Controller slot, you can change the protocol that the slot supports (affects all of the ports in that slot). If the slot supports Ethernet, you can change whether the all of the ports in the slot are to be aggregated.
If you select a particular port, you can change the protocol that the port supports. If the port supports Ethernet, you can change whether the all of the ports in the slot are to be aggregated.
