6 – Port Configuration Extending Port Transmission Distance

6.7

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.
