B5K 10Gb and 1Gb sfp port

[Simone_Magagnin]

Hi to everybody, on B5K switch when I use an 10Gb port (for example tg.1.49) for a uplink, can I use other sfp 1Gb port for other uplink? thanks.

Hi,

in general you can use ports with different speeds as uplinks. Spanning tree will prefer the faster link. If you use some other redundancy protocol instead of spanning tree, you need to check that the protocol supports different speeds.
