Q: Our Cisco 2960-XR comes with 2 fixed 10 Gigabit Ethernet SFP+ uplinks. Can we purchase SFP ports to connect to out server with 10GB NIC?
I search online and someone says: “The uplink port on the switch is usually a higher-speed port used to connect smaller local network to a larger network or connect to another higher-speed switches in the topology”. My question is if we can use the SFP+ uplink ports as normal ports to connect our new server.
A: If both server and switch NIC are SFP, that will work. However, adding 10GB NIC on server isn’t benefits for the serve. 10GB is more benefits for SAN or accessing data storage.
if server not support SFP based NIC card, only option for you 1G X 2qty port – Port-channel 2GB you can do.
If the uplink ports on the 2960-XR series switches are fixed, meaning if they are SFP+, they only support 10Gig optics and not 1Gig optics.
Make sure you enable QoS on those ports — because you will really, really need it.
