FTM State:
DISC STATE: In the topology discovery state.
LISTEN STATE: In the topology discovery state, and the FTM
slave device is listening.
HB STATE: The fabric operates normally.

Authentication mode for an XRN fabric
You can use the xrn-fabric authentication-mode command to
configure the authentication mode and password for an XRN fabric.
ID of the VLAN transmitting fabric synchronization information.
You can use the ftm fabric-vlan command to specify the VLAN used
to form an XRN fabric.
Status of the two fabric ports on a device:
Link-Down
Isolated (temporary): The fabric is not in a normal state yet, and
the fabric port is isolated temporarily.
Isolated (redundance port): Redundant link in a ring topology.
Isolated (reached max units)
Isolated (different system name): The fabric name of the device
directly connected to the switch and the existing fabric name of
the fabric are different.
Isolated (different version): The software version of the directly
connected device and that of the current device are different.
Isolated (auth failure): The XRN fabric authentication modes
configured for the local device and that of the fabric are not the
same, or the password configured does not match.
Isolated (connection error): Fabric port connection error occurs.
Disable: Fabric is disabled on the port.
Normal
Refer to the Operation Manual for the status and solution of the
problems.
Numbers of various negotiation packets:
Advertise
Advertise ACK
Heart Beat: Heat beat packet, which is used to advertise topology
connections to the units by the FTM-Master after convergence.
Left Check: Handshake packets between neighbors. They are
sent from the left port and used to monitor the state of the
neighbors periodically.
Right Check: Handshake packets between neighbors. They are
sent from the right port and used to monitor the state of the
neighbors periodically.
Auto update: Number of auto update packets sent and received
You can use the above numbers to analyze whether the
transmission of data among fabric units is normal, and thus to judge
whether the fabric operates normally.
