The following guidelines apply to buffer-to-buffer credit buffers on the 48-port 32-Gbps Fibre Channel
switching modules:
• Buffer-to-buffer credit buffers for ISL connections can be configured from a minimum of 2 buffers to a
• Buffer-to-buffer credit buffers for Fx port mode connections can be configured from a minimum of 1
• If you have installed an enterprise license, per port credits in a port group can be increased up to 800
