Configuring Switch Information 3 NOTE: If the product is attached to a fabric element, the product and element must be set to the same R_A_TOV value. If the values are not identical, the E_Port connection to the element fails and the product cannot communicate with the fabric. 4. At the E_D_TOV field, type a value between 2 through 600 tenths of a second (0.2 through 60 seconds). (The E_D_TOV value must be less than the R_A_TOV value.) NOTE: If the product is attached to a fabric element, the product and fabric element must be set to the same E_D_TOV value. If the values are not identical, the E_Port connection to the element fails and the product cannot communicate with the fabric. 5. Select from the Switch Priority drop-down list to set the product priority. Available selections are Default, Principal, and Never Principal. The default setting is Default. This value designates 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). Principal is the highest priority setting, Default is the next highest, and Never Principal is the lowest priority setting. The setting Never Principal means the switch is incapable of becoming a principal switch. If all switches are set to Principal or Default, the switch with the highest priority and the lowest world wide name (WWN) becomes the principal switch. At least one switch in a fabric must be set as Principal or Default. If all switches are set to Never Principal, all interswitch links (ISLs) will segment, causing a failure of connectivity. 6. Select from the Interop Mode drop-down list to set the product operating mode. This option does not display if the Operation Mode is S/3901. (S/390 Mode is not supported for loop devices.) This setting only affects the mode used to manage the product; it does not affect port operation. Available selections are: • McDATA Fabric 1.0-Select this option if the product is fabric-attached only to other directors or switches operating in McDATA Fabric 1.0 mode.

Configuring Switch Information
NOTE:
If the product is attached to a fabric element, the product and
element must be set to the same R_A_TOV value. If the values are not
identical, the E_Port connection to the element fails and the product
cannot communicate with the fabric.
4.
At the
E_D_TOV
field, type a value between
2
through
600
tenths
of a second (0.2 through 60 seconds). (The E_D_TOV value must
be less than the R_A_TOV value.)
NOTE:
If the product is attached to a fabric element, the product and
fabric element must be set to the same E_D_TOV value. If the values are
not identical, the E_Port connection to the element fails and the product
cannot communicate with the fabric.
5.
Select from the
Switch Priority
drop-down list to set the product
priority. Available selections are
Default
,
Principal
, and
Never
Principal
. The default setting is
Default
.
This value designates 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).
Principal
is the highest priority setting,
Default
is the next highest,
and
Never Principal
is the lowest priority setting. The setting
Never
Principal
means the switch is incapable of becoming a principal
switch. If all switches are set to
Principal
or
Default
, the switch
with the highest priority and the lowest world wide name
(WWN) becomes the principal switch.
At least one switch in a fabric must be set as
Principal
or
Default
. If
all switches are set to
Never Principal
, all interswitch links (ISLs)
will segment, causing a failure of connectivity.
6.
Select from the
Interop Mode
drop-down list to set the product
operating mode. This option does not display if the Operation
Mode is S/390
1
