Explanation:
According to the DCUCD training material, page 2-70:

Uplink ports in a Cisco UCS are those physical ports on the Fabric Interconnect that are dedicated for the connectivity to a LAN device external to Cisco UCS, for example: the connectivity to a Cisco Nexus 7000. These ports carry VLAN traffic only and are configured as IEEE 802.1q trunk ports to carry VLAN traffic for all the VLANs used in the service profiles for a particular fabric.
