Extending Port Transmission Distance
You can extend the distance over which an F_Port or G_Port port can transmit by
borrowing buffer credits from other ports. Refer to the SANbox 5000 Series Fibre
Channel Switch Installation Guide for information about extended credits and
transmission distance. Enter the Set Config Port command to borrow and
reallocate port credits as shown in the following example:
SANbox #> admin start
SANbox (admin) #> config edit
SANbox (admin-config) #> set config port
A list of attributes with formatting and current values will follow.
Enter a new value or simply press the ENTER key to accept the current value.
If you wish to terminate this process before reaching the end of the attributes
for the port being processed, press 'q' or 'Q' and the ENTER key to do so.
If you wish to terminate the configuration process completely, press 'qq' or
'QQ' and the ENTER key to so do.
