a. At the R_A_TOV field, enter 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.
b. At the E_D_TOV field, enter 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.
c. 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).
