Operation Manual – IRF FabricH3C S5600 Series Ethernet Switches-Release 1510 Chapter 1 IRF Fabric Configuration1-21.1.2 Introduction to RMON on IRFThe remote monitoring (RMON) configurations of the devices in a fabric are the same.The RMON configuration performed on a device of a fabric will be automaticallysynchronized to all devices in the fabric if the configuration does not conflict with that ofother devices in the fabric.If you configure the same entry in the same RMON group for devices of a fabric to bedifferent values, the value of the RMON group entry will be the one configured by thedevice with the smallest Unit ID when the devices are synchronized. Such amechanism eliminates configuration conflicts between the devices in a fabric.After the configurations are consistent, you can collect RMON history and statistics ofany unit from any switch in the fabric. For detailed information about RMON, refer to theSNMP-RMON Operation part in H3C S5600 Series Ethernet Switches OperationManual.1.2 Peer Fabric Port Detection1.2.1 Introduction to the Peer Fabric Port Detection FunctionAs the basis of the IRF function, the fabric topology management (FTM) modulemanages and maintains the entire topology of a fabric. The FTM module alsoimplements the peer fabric port detection function.A device can join a fabric only when the following conditions are met.z The number of the existing devices in the fabric does not reach the maximumnumber of devices allowed by the fabric.z The fabric names of the device and the existing devices in the fabric are the same.z The software version of the device is the same as that of the existing devices in thefabric.z The device passes the security authentication if security authentication is enabledin the fabric.1.2.2 Work Flow of the Peer Fabric Port Detection FunctionAfter a switch is powered on, the FTM module releases device information of the switchthrough the fabric ports. The device information includes Unit ID, CPU MAC, devicetype ID, fabric port information, and all fabric configuration information. The deviceinformation is released in the form of discovery packet (DISC). A new device can join afabric only when its DISC packets pass the authentication performed by the existingdevices in the fabric.z If a fabric port of a switch is connected to a non-fabric port, the switch will notreceive DISC packets from the peer. In this case, the switch cannot join the fabric.
