Changing System Configuration Parameters

• Sequence Level Switching
Check this box to enable frames of the same sequence from a particular group to be transmitted
together. When this option is not selected, frames are transmitted interleaved among multiple
sequences. Under normal circumstances, sequence-level switching should be disabled for better
performance. However, some host adapters have issues when receiving interleaved frames among
multiple sequences.
• Disable Device Probing
Set this mode only if the switch N_Port discovery process (PLOGI, PRLI, INQUIRY) causes an
attached device to fail. When set, devices that do not register with the Name Server are not present
in the Name Server data base.
• Per-Frame Routing Priority
Choose to select or deselect per-frame routing priority. When enabled, the virtual channel ID is
used in conjunction with a frame header to form the final virtual channel ID.
• Suppress Class F Traffic
Applies only if VC-encoded address mode is also set. When checked, translative addressing (which
allows private devices to communicate with public devices) is disabled.
• Insistent Domain ID Mode
Set this mode to make the current domain ID insistent across reboots, power cycles, and failovers.
This mode is required fabric wide to transmit FICON

data.
