Figure 2-85 Configure Switch Parameters Dialog Box
a. At the Preferred Domain ID field, type a value between 1
through 31. The domain ID uniquely identifies each switch in
a fabric.
NOTE: If the switch is attached to a fabric element, the switch and
element must have unique domain IDs. If the values are not unique,
the E_Port connection to the element segments and the switch cannot
communicate with the fabric.
b. Click the Insistent Domain ID check box to enable or disable
this parameter. A check mark in the box indicates the
parameter is enabled. When the parameter is enabled, the
domain ID configured in the Preferred Domain ID field
becomes the active domain identification when the fabric
initializes.
c. Click the Rerouting Delay check box to enable or disable this
parameter. A check mark in the box indicates the parameter is
enabled. When the parameter is enabled, traffic is delayed
through the fabric by the specified E_D_TOV. This delay
ensures Fibre Channel frames are delivered to their
destination in order, even if a change to the fabric topology
creates a new (shorter) transmission path.
d. Click the Domain RSCNs check box to enable or disable this
parameter. A check mark in the box indicates the parameter is
enabled. When the parameter is enabled, attached devices can
register to receive notification when another attached device
changes state.
