Buffer credit management
23
Buffer credits for each switch model
Table 79
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. The number in the Unreserved buffers column
is the number with QoS enabled. This number is higher if QoS is not enabled.
For the FC8-x port blades, the first number in the Unreserved buffers column designates the
number of unreserved buffers per port group without buffer optimized mode; the second number
designates the unreserved buffers with buffer optimized mode enabled on the slot. Use the
bufOpMode command to display or change the buffer optimized mode.
