Fabric Interconnect Port Types:

By default, all fabric interconnect ports are unconfigured. For Ethernet LAN connectivity, fabric interconnect ports can be in the following states:

Unconfigured — Port is not configured and cannot be used.

Server Port — Port is configured for downlink connection to an IOM Fabric Extender (FEX) module in a blade chassis.

Uplink Port — Port is configured for uplink connection to the upstream Ethernet switch. Uplink ports are always configured as trunk ports.

Disabled—Port is configured either as an uplink or server port and is currently disabled by the administrator.
