Field Descriptions
Fabric Parameters
BB Credit Use to configure the number of buffers that are available to
attached devices for frame receipt. The default BB Credit is
16. The range is 1—16.
R_A_TOV Use to configure the Resource Allocation Time Out 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
4000—120000.
E_D_TOV Use to configure the 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—5000.
Data Size Use to configure (in bytes) the largest possible data field size.
The valid range is 256—2112.
Sequence Switching Select check 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.
VC Encoded
Address Mode
Set this mode only if the fabric includes a StorageWorks
SAN switch.
When set, the frame source and destination address use an
address format that is compatible with StorageWorks SAN
switches.
