Ports are grouped into quads, each of which consists of four adjacent ports that share a
common pool of frame buffers. The possible quad groupings are ports:
•
0 – 3
•
4 – 7
•
8 – 11
•
12 – 15
Certain buffers are dedicated for each port, and others are shared among the ports. In
extended fabric mode, one port is given an increase of dedicated buffers from this pool.
L0 = Represents an Extended Fabric mode of 10 kilometers.
L1 = Represents an Extended Fabric mode of 50 kilometers.
L2 = Represents an Extended Fabric mode of 100 kilometers.
Fx = F_Port or FL_Port that is used when connected to devices.
E = E_Port that is used for interswitch connectivity.
Because the total number of frame buffers in a quad is limited, the following Extended
Fabric port matrix introduces a combination of long distance ports that are available:
