Configuring the Switch
If no device is logged in, no WWN appears on the Attached 
WWN line. If the user then enables port binding, the port will be 
bound to a WWN of 0, essentially preventing any device from 
logging in until binding is disabled,or the bound WWN is 
updated to a new WWN setting.
◆ WWN — This entry allows you to enter a WWN (in the format 
xx.xx.xx.xx.xx.xx.xx.xx) or nickname of a device that will be 
bound to the port. If port binding is enabled, this device has 
exclusive use of the port, even if another device is logged in. (If 
binding is not enabled, this WWN/nickname will be stored.)
If port binding is enabled and no attached node matches the 
WWN/nickname in the WWN field, a warning (Figure 5-7 on 
page 5-12) appears. If you click Continue at that warning, any 
node that is logged in will be logged out. If the device identified 
in the WWN field logs in, it will become bound to the port and 
will be able to communicate.
