Major Fibre Channel Port Features
Major Fibre Channel Port Features
Major Fibre Channel port features include:
•Each Switch chassis has 16 Fibre Channel ports. Each port operates at 1062.5 megabaud.
•Any or all 16 ports may be:
Fabric Ports Fabric ports connect to fibre channel public devices and device loops. A fabric port is self configuring as an F_Port for a public device or as an FL_port for a loop of public devices. Refer to “Fabric Port Overview” on page
SL_Ports Segmented Loop Ports (SL_Ports) allow you to divide a Fibre Channel Private Loop into multiple segments. Each segment of the loop can pass frames around as an independent loop and can also connect through the fabric to other segments of the same loop. Refer to “Segmented Loop Port (SL_Port) Overview” on page
TL_Ports. Each Translated Loop Port (TL_Port) connects to a private loop and allows connectivity between the private loop devices on the loop and
T_Ports. Trunk Ports (T_Ports) allow the interconnection of multiple chassis to form larger fabrics. Refer to Section 5
•All ports support Class 2 and Class 3 Fibre Channel service. Refer to Appen- dix A Reference Information for more information.
•The Switch supports the maximum Fibre Channel frame size (2148 bytes) for Class 2 and 3 Fibre Channel service. Refer to Appendix A Reference Infor- mation for more information.
•All ports are supported by GigaBit Interface Converters (GBICs). GBICs contain the transmitters and receivers that connect to the interconnection media. Each GBIC is “hot pluggable”.
•Each port has eight buffer credits. This feature allows a cable length up to 13 km at 1 Gbps without performance degradation. F_Port and T_Port credits can be extended by chaining ports together. Refer to “Port Buffer Credits” on page
