BB Credit The buffer-to-buffer credit is the number of buffers available to attached devices for frame
receipt. The default BB Credit is 16. The range is 1–27.
R_A_TOV Resource allocation timeout value (in milliseconds). This variable works with the E_D_TOV
to determine switch actions when presented with an error condition. The default is 10000.
The possible range is (2*E_D_TOV) –120000. Values must be multiples of 1000.
E_D_TOV Error detect timeout 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 - (R_A_TOV/2)
Addressing mode Displays the addressing mode present in the switch.
Datafield size The largest possible data field size (in bytes). The valid range is 256–2112.
Sequence Level
Switching
Select 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 database.
Per-Frame Routing
Priority
Select whether to select 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 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 insistent across reboots, power cycles, and
failovers. This mode is required fabric wide to transmit FICON
data.
WWN-based Persistent
PID
Set this mode to configure a PID persistently using a device’s WWN. When the device logs
into the switch, the PID is bound to the device WWN. Refer to “WWN-based Persistent PID
assignment” on page 43.
