Enabling Insistent Domain ID Mode (FICON only)
When insistent domain ID (ID_ID) mode is enabled, the current domain setting for the switch is
insistent; that is, the same ID is requested during switch reboots, power cycles, CP failovers, firmware
downloads, and fabric reconfigurations. If the fabric does not assign the insistent domain ID, the switch
segments from the fabric.
This parameter is for use with FICON only.
To enable insistent domain ID mode
1. Launch the Switch Admin module as described on page 4-3.
2. Disable the switch as described in “Enabling and Disabling a Switch” on page 4-5.
3. Click the Configure tab.
4. Click the Fabric subtab.
5. Check the Insistent Domain ID Mode checkbox.
6. Click Apply.
7. Enable the switch as described in “Enabling and Disabling a Switch” on page 4-5.
Configuring Virtual Channel Settings
You can configure the parameters for eight virtual channels to enable fine-tuning for a specific
application. You cannot modify the first two virtual channels, which are reserved for switch internal
functions.
VC Priority specifies the class of frame traffic given priority for a virtual channel.
Caution
The default virtual channel settings have already been 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.
