Zoning with Switch Binding enabled
Note that SANtegrity Binding has no effect on existing zoning configurations. However, note that if
a device WWN is in a specific zone, but the WWN is not in the Switch Membership List, the
device cannot log in to the director or switch port and cannot connect to other devices in the zone
with Switch Binding enabled.
Enterprise Fabric Mode
Enterprise Fabric Mode is an option available on the Fabrics menu of HAFM if the SANtegrity
Binding feature key is installed. This option automatically enables the following features and
operating parameters that are necessary in multiswitch Enterprise Fabric environments. Note that
there are specific requirements for disabling these parameters and features when the director or
switch is offline or online.
Features and parameters enabled
The following features and parameters are enabled by the Enterprise Fabric Mode option:
• Fabric binding
This is a SANtegrity Binding feature enabled through the Fabrics menu in HAFM that allows or
prohibits switches and directors from merging with a selected fabric. See ” Enable/disable and
Online State functions ” on page 152 for details on enabling/disabling Fabric Binding with
Enterprise Fabric Mode enabled.
• Switch binding
This is a SANtegrity Binding feature enabled through the Configure menu in the Element
Manager that allows or prohibits switches and/or directors from connecting to switch E_Ports,
and prohibits devices from connecting to F_Ports. See ” Enabling or disabling switch binding ”
on page 154 for details on enabling/disabling Switch Binding with Enterprise Fabric Mode
enabled.
• Rerouting delay
This is a parameter in the Configure Switch Parameters dialog box, available from the
Configure menu in the Element Manager.
Rerouting Delay ensures that frames are delivered through the fabric in order 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 because 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
box of the Configure Fabric Parameters dialog box (Configure menu). This delay enables
frames sent on the old path to exit to their destination before new frames begin traversing the
new path.
If Enterprise Fabric Mode is enabled, this option is automatically enabled and cannot be
disabled unless the switch is offline. In this case, disabling Rerouting Delay also disables
Enterprise Fabric Mode.
