Figure 8: Fabric Parameters tab view
a. At the BB_Credit field, type a value between 1 and 60 . (This field is not
available for the Edge Switch 2/24.) Configure the product 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 industry specification, Fibre Channel
Physical and Signaling Interface.
b. At the R_A_TOV field, type a value between 10 through 1200 tenths of
a second (1 through 120 seconds). (The R_A_TOV value must be greater
than the E_D_TOV value.)
Note: If the product is attached to a fabric element, the product and element must be
set to the same R_A_TOV value. If the values are not identical, the E_Port connection to
the element fails and the product cannot communicate with the fabric.
c. At the E_D_TOV field, type a value between 2 through 600 tenths of a
second (0.2 through 60 seconds). (The E_D_TOV value must be less than
the R_A_TOV value.)
