•

E_D_TOV: Error detect time-out value (in milliseconds). This timer is used to flag a potential error

condition when an expected response is not received within the set time. The valid range is 1000

through 5000.

•

Datafield size: The largest possible data field size (in bytes). The valid range is 256 through 2112.

•

Switch PID Format: Select a switch port identifier (PID) format from one of the following:

• Format 1 (0-base, 256 encoding)

• Format 2 (16-base, 256 encoding)

•

Sequence Level Switching: Select this check box to enable frames of the same sequence from a specific

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. Set this mode only if the switch N_Port discovery

process (PLOGI, PRLI, INQUIRY) causes an attached device to fail.

•

Per-Frame Routing Priority: Choose to select or deselect per-frame routing priority. When enabled, the

virtual channel ID is used 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 selected,

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 persistent across reboots,

power cycles, and failovers. This mode is required fabric-wide to transmit FICON

data.
