Operation Manual – IRF Fabric
Quidway S3900 Series Ethernet Switches-Release 1510
Note:
The S3900-SI series switches, except S3924-SI, only support basic IRF fabric
feature, that is, DDM (distributed device management) function.
The S3900-EI series switches support enhanced IRF fabric feature, including DDM,
DRR (distributed redundancy routing) and DLA (distributed link aggregation).

1.1.2 Introduction to RMON on IRF

The RMON configurations of the devices in a fabric are the same. The RMON
configuration performed on a device of a fabric will be automatically synchronized to all
devices in the fabric if the configuration does not conflict with those of other devices in
the fabric.
If you configure the same entry in the same RMON group for devices of a fabric to be
different values, the entry values of all the conflicting devices will adopt that of the
conflicting device with the smallest Unit ID when you synchronize the devices. Such a
mechanism eliminates configuration conflicts between the devices in a fabric.
After the device configurations converge, you can collect RMON history and statistics
data of any unit from any switch in the fabric.

1.2 Peer Fabric Port Detection

1.2.1 Introduction to the Peer Fabric Port Detection Function

As the basis of the IRF function, the fabric topology management (FTM) module
manages and maintains the entire topology of a fabric. The FTM module also
implements the peer fabric port detection function.
A device can join a fabric only when the following conditions are met.
The number of the existing devices in the fabric does not reach the maximum
number of devices allowed by the fabric.
The fabric names of the device and the existing devices in the Fabric are the
same.
The software version of the device is the same as that of the existing devices in the
fabric.
The device passes the security authentication if security authentication is enabled
in the fabric.

1.2.2 Work Flow of the Peer Fabric Port Detection Function

After a switch is powered on, the FTM module releases device information of the switch
through the fabric ports. The device information includes Unit ID, CPU MAC, device
