I am trying to find documentation on this through the Cisco website but have been unsuccessful. I have a WS-C2960S-24PD-L switch with two SFP+ ports. The data sheet says for uplinks - "2 Ten Gigabit Ethernet SFP+ or 2 One Gigabit Ethernet SFP ports". Does anyone know if it is possible to use one of each? I need to run one 10G uplink and one 1G uplink. Thanks.
