Buffer credit management

Buffer credits for each switch model
shows the total ports in a switch or blade, number of user ports in a port group, and the
unreserved buffer credits available per port group.
SPIK
For the FC8-x blades, the first number in the Unreserved buffers column designates the number of
unreserved buffers per port group in Brocade DCX and DCX-4S platforms; the second number
designates the unreserved buffers in a Brocade 48000 director. For example, for the FC8-48, 1228
designates the number of unreserved buffers per port group and 1324 number designates the
number in a Brocade 48000 director. Additional buffers are available with the Brocade 48000
director because of fewer buffers allocated for back-end port connections. Implementing extended
fabrics between Brocade 2xxx switches and switches running any Fabric OS v6.x is not supported.
