z
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 UP
port of the switch is sent by the DOWN port of the peer device, the packet is
regarded legal. Otherwise, the packet is regarded illegal and is discarded.
z
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.
z
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 that of its own are the same. If not, the
received DISC packet is illegal and will be discarded.
z
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
The IRF Fabric peer detection function outputs different prompt information according
to the connection conditions of the devices within the Fabric. You can refer to the
following table to perform corresponding adjustment and maintenance for the Fabric.
Table 1-1 Prompt information analysis and solution

Solution
normal
it indicates the fabric operates
properly
temporary
it indicates the port status is changing
redundance port
it indicates the port is the redundant
port in fabric ring topology
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
