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.
Principal is the highest priority setting, Default is next, and
Never Principal is the lowest. At least one switch in a fabric
must be set as Principal or Default. If all switches are set to
Never Principal, all ISLs segment.
d. Select from the Interop Mode drop-down list to set the product
operating mode. This setting affects the management mode
and does not affect port operation. Available selections are:
• McDATA Fabric 1.0 - Select this option if the product is
fabric-attached only to other McDATA directors or
switches operating in McDATA fabric mode.
• Open Fabric 1.0 - Select this option (default) for managing
heterogeneous fabrics and if the product is fabric-attached
to McDATA directors or switches and other open-fabric
compliant switches.
NOTE: With Open Fabric 1.0 enabled, the default zone set is disabled.
3. Click OK to save and activate changes.
