    2 USING QUICKLOOP You can enable or disable QuickLoop for either the entire switch or for particular ports. When QuickLoop is enabled on a port, the port is added to the same QuickLoop to which the switch belongs. A QuickLoop can be either "single-switch," where all looplets are located on a single-

    E_port Expansion port. A port is designated an E_Port when it is used as an interswitch expansion port to connect to the E_Port of another switch, to build a larger switch fabric, or to build a two-switch QuickLoop configuration. Sometimes, a single device is attached to a port. In this case the
