Configuring virtual channel settings
You can configure parameters for eight virtual channels (VC) to enable fine-tuning for a specific
application. You cannot modify the first two virtual channels because these are reserved for switch
internal functions.
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.
Perform the following procedure to configure the virtual channel settings.
1. Open the Switch Administration window as described in “Opening the Switch Administration
window” on page 35.
2. Disable the switch as described in “Enabling and disabling a switch” on page 40.
3. Select the Configure tab.
4. Select the Virtual Channel subtab.
5. Enter a value in the VC Priority field you want to change.
The only valid numeric values for all fields are either “2” or “3”.
6. Click Apply.
7. Enable the switch as described in “Enabling and disabling a switch” on page 40.
