a. At the BB_Credit field, type a value between 1 an 60 buffers. The default is
16. Use a value of 60 buffers only for extended distance port operation.
b. At the R_A_TOV field, type a value between 10 through 1200 tenths of a
second (one through 120 seconds). The default is 10 seconds (100 tenths).
All fabric-attached switches must be set to the same R_A_TOV. If the value is
not compatible, the E_Port connection to the switch segments and the switch
cannot communicate with the fabric. In addition, the R_A_TOV must be
greater than the E_D_TOV.
c. At the E_D_TOV field, type a value between 2 through 600 tenths of a second
(0.2 through 60 seconds). The default is 20 tenths of a second (2 seconds).
All fabric-attached switches must be set to the same E_D_TOV. If the value is
not compatible, the E_Port connection to the switch segments and the switch
cannot communicate with the fabric. In addition, the E_D_TOV must be less
than the R_A_TOV.
d. The switch priority value designates the fabric's principal switch. The
principal switch controls the allocation and distribution of domain IDs for all
fabric directors and switches (including itself). At the Switch Priority field,
select Principal, Never Principal, or Default (the default setting is Default).
