ATTENTION
The default virtual channel settings are already optimized for switch performance. Changing the default
values can improve switch performance, but can also degrade performance. Do not change these
settings without fully understanding the effects of the changes.
VC Priority specifies the class of frame traffic given priority for a virtual channel.
To configure the virtual channel settings, perform the following steps.
1. Open the Switch Administration window as described in Opening the Switch Administration window
on page 52
