The following sections help you troubleshoot problems with Fabric Attach (FA) using either the Command Line Interface (CLI) or the Enterprise Device Manager (EDM).
Troubleshoot FA in the following sequence:
Verify FA configuration:
As a first step, for proper operation, verify that FA is enabled properly at both the global and interface levels. Use the procedures in this section to verify FA configuration.
Verify LLDP port-level transmission and reception:
LLDP operates at the interface level. Enabling FA at the port level automatically enables LLDP transmission and reception at the port level. Similarly, enabling FA at the MLT level automatically enables LLDP transmission and reception for all ports in that MLT. Use the procedures in this section to verify LLDP interface (port or MLT) statistics.
Verify FA discovery, I-SID-to-VLAN mapping assignments and Switched UNI I-SID creation:
After you verify LLDP transmission, verify that FA element discovery completed successfully. After a successful FA discovery, FA clients can send I-SID-to-VLAN mapping assignments to the FA Server on an FA-enabled port or MLT. The FA server accepts or rejects these mapping assignments. A prerequisite to successful mapping assignments is that IS-IS and SPBM are properly configured on the FA server. Successful FA mappings result in the creation of ELAN I-SIDs with end-points of type Switched UNI on the FA Server switch.
