Online state functions
In order for Fabric Binding to function, specific operating parameters and optional features must be
enabled. Also, there are specific requirements for disabling these parameters and features when
the director or switch is offline or online. Be aware of the following:
• Because switches are bound to a fabric by World Wide Name (WWN) and domain ID, the
Insistent Domain ID option in the Configure Switch Parameters dialog box is automatically
enabled if Fabric Binding is enabled.
• If Fabric Binding is enabled and the switch is online, you cannot disable the Insistent Domain
ID.
• If Fabric Binding is enabled and the director or switch is offline, you can disable the insistent
domain ID, but this will disable Fabric Binding.
• You cannot disable Fabric Binding or Switch Binding if Enterprise Fabric Mode is enabled.
However, if Enterprise Fabric Mode is disabled, you can disable Fabric Binding, Switch
Binding, or both.
Switch binding
This feature is managed through the Switch Binding submenu options available on the Element
Manager Configure menu. Using Switch Binding, you can specify devices and switches that can
attach to director and switch ports. This provides security in environments that include a large
number of devices by ensuring that only the intended set of devices attach to a switch or director.
Configuring switch binding—overview
To configure Switch Binding, you must first activate the feature using the Switch Binding State
Change dialog box while selecting the type of port where you want to restrict connection
(connection policy). Possible selections are E_Ports, F_Ports, or all types.
If the director or switch is online, activating Switch Binding populates the Membership List in the
Switch Binding - Membership List dialog box (Element Manager) with the following WWNs
currently connected to the director or switch, depending on the connection policy set in the State
Change dialog box:
• WWNs of devices connected to F_Ports (F_Port connection policy). The WWN is the WWN of
the attached device's port.
• WWNs of switches connected to E_Ports (E_Port connection policy). The WWN is the WWN
of the attached switch.
• WWNs of devices connected to F_Ports and switches connected to E_Ports (all-ports connection
policy).
Notes
• When the Switch Binding feature is first installed and has not been enabled, the Switch
Membership List is empty. When you enable Switch Binding, the Membership List is populated
with WWNs of devices, switches, or both that are currently connected to the switch.
• If the switch is offline and you activate Switch Binding, the Membership List is not automatically
populated.
• Edits to the Switch Binding Membership List will be maintained when you enable or disable
Switch Binding.
