type ID, fabric port information, and all fabric configuration information. The device
information is released in the form of discovery packet (DISC). A new device can join a
fabric only when its DISC packets pass the authentication performed by the existing
devices in the fabric.
If a fabric port of a switch is connected to a non-fabric port, the switch will not
receive DISC packets from the peer. In this case, the switch cannot join the fabric.
If the switch can receive DISC packets sent by the peer, the FTM module
determines whether peer sending ports correspond to local receiving ports
according to information in the packet. That is, if a DISC packet received by the left
port of the switch is sent by the right port of the peer device, the packet is regarded
legal. Otherwise, the packet is regarded illegal and is discarded.
If the maximum number of devices allowed by the fabric is reached, the devices in
the fabric do not send DISC packets and discard the received DISC packets. This
prevents new devices from joining the fabric.
After receiving a DISC packet from a directly connected device, a device in a fabric
checks whether the device information (that is, the Fabric name and software
version) contained in the packet and those of its own are the same. If not, the
received DISC packet is illegal and will be discarded.
If authentication is enabled in the fabric, the current device in the fabric
authenticates received packets sent by new directly connected devices. Packets
that fail to pass the authentication will be discarded.

1.2.3 Prompt Information and Solution

I. Normal
If the port displays "normal", it indicates the fabric operates properly.
II. Temporary
If the port displays "temporary", it indicates the port status is changing.
III. Redundance port
If the port displays "redundance port", it indicates the port is the redundant port in fabric
ring topology.
Note:
The "normal", "temporary" and "redundance port" information do not mean a device or a
fabric operates improperly. No measure is needed for any of these three types of
information.
