Command Modes Administrator.
Command History
Usage Guidelines Use this command to set the data buffer credit capacity for all the storage router FC ports. The port buffer
credit is used to determine how many maximum sized frames can be sent to a recipient before the sending
port must wait for an acknowledgement. When the acknowledgement is received, the sending port can
continue by sending the next frame. Port buffer credits are required when buffer-to-buffer flow control
is in use. Buffer-to-buffer flow control occurs between directly connected FC ports.
The data buffer credit capacity must be the same for all switches across the fabric, and should be set to
the lowest system-wide setting.
Examples The following example sets the data buffer credit capacity to 15:
[SN5428-2A]# fcswitch interop-credit 15
credit The data buffer credit capacity, also known as the buffer-to-buffer credit
value. The credit variable is an integer between 0 and 255 inclusive. The
default value is 12.
