Configure Fabric Attach Interface-level Settings

Use this procedure to configure FA interface-level settings or view existing interface-level settings.

You can enable Fabric Attach on a port, static MLT or an LACP MLT. Enabling FA on a port not only enables tagging but also disables spanning tree on that port. Enabling FA on an MLT enables FA on all ports of the MLT. When FA is enabled on ports in an MLT or LACP MLT, tagging is enabled and spanning tree is disabled on all those ports.

Before you begin

Ensure that FA is enabled globally on the switch.

About this task

Enabling FA on a port or MLT is necessary for element discovery. On the FA Server, FA is enabled globally by default. However, you must explicitly enable FA on a desired port or MLT interface, following which the FA Server can begin transmitting LLDP PDUs that contain the element discovery TLVs. This information is received by FA Client and FA Proxy devices, which in turn also transmit their FA capabilities and settings. After the element handshake completes, the FA Server receives I-SID-to-VLAN assignment mappings from the connected client or proxy devices, on that port or MLT.

Procedure

In the navigation pane, expand Configuration > Fabric.
Select Fabric Attach.
Select the Ports tab.

The FA interface-level settings are displayed.
Select the fields on this window to modify existing settings.
Select Apply to save your changes.
To configure FA on a new port or MLT interface:
1. Select Insert.
  
  The Insert Ports dialog box opens.
2. To configure FA on a port, enter a port number in the format slot/port[/sub-port], or select Port to select from a list of available ports.
3. To configure FA on an MLT, enter an MLT ID or select Mlt to select from a list of configured MLTs.
  
  Note
  
  FA is successfully enabled on the MLT, only if all ports of the MLT have FA successfully enabled. Enabling FA enables LLDP on all ports. Tagging is enabled and spanning tree is disabled.
4. Select Insert to save your changes.
To remove (delete) FA on a port or MLT:
1. In the content pane, select a port or MLT from the list.
2. Select Delete.
Caution

Removing FA on an interface flushes all FA element discovery and I-SID-to-VLAN mappings associated with that interface.

Ports Field Descriptions

Use the data in the following table to use the Ports tab.


Name	Description
IfIndex	Specifies the interface (port or MLT) on which Fabric Attach is configured.
State	Specifies the current state of the Fabric Attach port. It is either enabled or disabled. This field indicates whether LLDP PDUs (that include FA TLVs) are generated on the port (enabled) or not (disabled).
MsgAuthStatus	Specifies the Fabric Attach message authentication status on the port. It is either enabled or disabled.
MsgAuthKey	Specifies the Fabric Attach message authentication key for the associated port. The maximum length of this key is 32 characters.
MgmtIsid	Specifies the Fabric Attach management I-SID for the associated port. The range is 0 to 16777215. A zero value indicates that the management I-SID is not specified for the interface.
MgmtCvid	Specifies the Fabric Attach management customer VLAN ID (C-VID) for the interface. A zero value indicates that no C-VID is specified for the interface. Using the maximum configuration value for your switch indicates the port is untagged. Platform support determines the C-VID range.
TCNEnable	Specifies whether the associated Fabric Attach interface can receive Topology Change Notification (TCN) BPDUs from ISW-Series Managed Industrial Ethernet Switches.
Origin	Specifies the origin of Fabric Attach port, either manually configured through CLI or EDM, or dynamically configured through Auto-sense.
