Configuring the Switch
Insistent
This option is not supported unless the SANtegrity feature is installed. Click the check
box to remove or add a checkmark. The default state is disabled (no checkmark).
When a checkmark displays, the domain ID configured in the Preferred Domain ID
field will become the active domain identification when the fabric initializes. See the
following notes:
• This option is required if Enterprise Fabric mode (optional SANtegrity feature) is
enabled. Refer to Insistent Domain Identification (ID) on page 6-15 for details.
• If you enable Insistent Domain while the Switch or Director is online, the
Preferred Domain ID will change to the current active domain ID if the IDs are
different.
CAUTION: If a Switch with a duplicate domain ID exists in the fabric, both Switches'
E_Ports will segment when they try to join.
Rerouting Delay
Placing a check mark in the check box to the left of the Rerouting Delay option
enables rerouting delay. This option is only applicable if the configured Switch is in a
multiSwitch fabric. The default state is disabled.
Enabling the rerouting delay ensures that frames are delivered in order through the
fabric to their destination. If there is a change to the fabric topology that creates a new
path (for example, a new Switch is added to the fabric), frames may be routed over this
new path if its hop count is less than a previous path with a minimum hop count. This
may result in frames being delivered to a destination out of order since frames sent
over the new, shorter path may arrive ahead of older frames still in route over the older
path.
If rerouting delay is enabled, traffic ceases in the fabric for the time specified in the
E_D_TOV field of the Configure Fabric Parameters dialog box. This delay allows
frames sent on the old path to exit to their destination before new frames begin
traversing the new path.
NOTE: This option is required if Enterprise Fabric mode (optional SANtegrity feature) is
enabled. Refer to Rerouting Delay on page 6-13 for details.
