3. Set the fabric parameters:

Enter a value from 10 through 1200 tenths of a second (one through 120 seconds) in the

R_A_TOV box.

The default is 10 seconds (100 tenths).

NOTE: 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. Enter a value from 2 through 600 tenths of a second (0.2 through 60 seconds) in the

E_D_TOV box.

The default is 20 tenths of a second (2 seconds).

NOTE: 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. Select Principal, Never Principal, or Default in the Switch Priority box.

The default setting is Default. 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 Edge Switches (including itself).

d. Select one of the following from the Interop Mode drop-down list:

• Homogeneous Fabric—Select this mode if the fabric contains only HP Edge Switches and

Directors that are operating in Homogeneous Fabric mode.

• Open Fabric 1.0—Select this mode if the fabric contains HP Directors and Edge Switches,

as well as other open-fabric compliant switches. Select this mode for managing

heterogeneous fabrics.
