a. At the R_A_TOV field, type a value between 10 through 1200
tenths of a second (one through 120 seconds). Ten seconds
(100) is the recommended value. The R_A_TOV value must
exceed the E_D_TOV value.
b. At the E_D_TOV field, type a value between 2 through 600
tenths of a second (0.2 through 60 seconds). Two seconds (20)
is the recommended value.
NOTE: Fabric elements must be set to the same R_A_TOV and
E_D_TOV values. An ISL between fabric elements with different
values segments and prevents communication.
c. Select from the Switch Priority drop-down list to designate the
fabric’s principal switch. The principal switch is assigned a
priority of 1 and controls the allocation and distribution of
domain IDs for all fabric elements (including itself). Available
selections are Default, Principal, and Never Principal.
