Cisco MDS 9148 Fabric Switch BB_Credit Buffers

Table 14-10 lists the BB_credit buffer allocation for 48-port 8-Gbps Fibre Channel switches.

Table 14-10 48-Port 8-Gbps Fabric Switch BB_Credit Buffer Allocation

BB_Credit Buffer Allocation Type	BB_Credit Buffers Per Port Group	BB_Credit Buffers Per Port
		ISL1	Fx Port
Default BB_credit buffers	128	32	32
Maximum configurable BB_credit buffers on 8-Gbps mode	128	125	125

1ISL = E port or TE port.

The following considerations apply to BB_credit buffers on 48-port 8-Gbps Fabric Switches:

• BB_credit buffers can be configured from a minimum of 1 buffer to a maximum of 32 buffers per port when the ports are in F or FL mode.
• BB_credit buffers can be configured from a minimum of 2 buffers to a maximum of 32 buffers per port when the ports are in E or TE mode.
