Troubleshooting Guide

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
1. In the navigation pane, expand the Configuration > Edit > Fabric Attach folders.
2. Click the Ports tab.
The FA interface-level settings are displayed.
3. To modify existing settings, double-click on the fields on this window. After making the
required changes, click Apply to save your changes.
4. To configure FA on a new port or MLT interface:
a. Click Insert.
The Insert Ports dialog box appears.
b. To configure FA on a port, enter a port number in the format slot/port[/sub-port], or click
Port to select from a list of available ports.
c. To configure FA on an MLT, enter an MLT ID or click 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.
d. Click Insert to save your changes.
5. To remove (delete) FA on a port or MLT:
a. In the content pane, select a port or MLT from the list.
b. Click Delete.
Caution:
Removing FA on an interface flushes all FA element discovery and I-SID-to-VLAN
mappings associated with that interface.
