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 multi-switch 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 dialog box. This delay allows frames sent on the
old path to exit to their destination before new frames begin traversing the
new path.
Domain RSCNs
Use this check box to enable Domain register for state change notifications
(domain RSCNs). Domain RSCNs are sent between end devices in a fabric to
provide additional connection information to host bus adapters (HBA) and
storage devices. As an example, this information might be that a logical path
has been broken because of a physical event, such as a fiber optic cable being
disconnected from a port. Consult with your HBA and storage device vendor
to determine if enabling Domain RSCNs will cause problems with your HBA
or storage products. For example, some hardware bus adapters (HBAs) may
log out, then log back into the fabric when they receive an RSCN, thereby
disrupting Fibre Channel traffic.
This option is required if Enterprise Fabric Mode (optional SANtegrity Binding
Suppress RSCNs on Zone Set Activations
Fabric format domain register for state change notifications (RSCNs) are sent
to ports on the switch following any change to the fabric's active zone set.
These changes include activating and deactivating the zone set, or enabling
and disabling the default zone. When the Suppress RSCNs on Zone Set
