Fabric Parameters
Configure the following parameters as required by your fabric.
BB_Credit
Configure the director 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 director’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 between 10 tenths and 1200 tenths (1 through 120 seconds).
