Figure 20 Configure Fabric Parameters dialog box

NOTE: Ordinarily, you do not need to change values in this dialog box from their defaults.

The only exception is the Preferred Domain ID. Change this value if the switch will participate

in a multiswitch fabric.

3. Use information under ”Fabric parameters” on page 45 to change settings as required for

Fabric parameters

Configure the following parameters as required by your fabric.

BB_Credit

Configure the switch to support buffer to buffer credit (BB_Credit) from 1 through 60. This is the

value used for all ports, except those configured for extended distance buffering (10-100 km). The

default value is 16. For a description of the buffer-to-buffer credit, refer to the industry specification,

Fibre Channel Physical and Signaling Interface.

R_A_TOV

Configure resource allocation time-out value (R_A_TOV) in tenth-of-a-second increments. This

variable works with the error detect time-out value (E_D_TOV) variable to control the switch’s

behavior when an error condition occurs. Resources are allocated to a circuit when errors are

detected and are not released for reuse until the time set by the R_A_TOV value expires. The default

value is 100 tenths (10 seconds). Set a value from 10 tenths through 1200 tenths (1 through 120

seconds).
