Configuring the Director
Fabric Parameters
The fabric parameters are described below:
Figure 5-4
Configure Fabric Parameters Dialog Box
BB_Credit
Configure the director to support buffer to buffer credit (BB_Credit)
from 1 through 60. (The default value is 16.) All ports use this value,
except those ports configured for extended distance buffering (10 to
100 km), which always use a BB_Credit value of 60. (Refer to
Configuring Ports on page 5-19 for information on enabling extended
distance buffering.)
For a description of buffer-to-buffer credit, refer to the industry
specification Fibre Channel Physical and Signaling Interface.
To enable extended distance operation on a port, it is not necessary to
change the BB_Credit value for the entire switch. You can enable
extended distance on a port-by-port basis without taking the entire
switch off line.
By enabling the extended distance feature on a port, you are setting
the individual port BB_Credit to 60. Refer to 10-100 km on page 5-21
for details on enabling this option.
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. Set a value in the range
