Operation Manual – IRF FabricH3C S5600 Series Ethernet Switches-Release 1510 Chapter 1 IRF Fabric Configuration1-51.3 IRF Fabric Configuration1.3.1 Introduction to IRF Fabric ConfigurationFTM provides user interfaces. You can configure unit IDs, fabric name by using arelated command.Table 1-2 Configure an IRF FabricTask Description Related sectionSet and save the unit ID for aswitch Optional Section 1.3.2 “Setting a UnitID for a Switch”Specify the fabric ports for aswitch Required Section 1.3.3 “Specifying theFabric Port of a Switch“Set the unit name for a switch Optional Section 1.3.4 “Assigning aUnit Name to a Switch”Set a name for the IRF fabric Required Section 1.3.5 “Assigning anIRF Fabric Name to a Switch”1.3.2 Setting a Unit ID for a SwitchOn the switches that support automatic numbering, FTM will automatically number theswitches to constitute an IRF fabric, so that each switch has a unique unit ID in thefabric. You can use the command in the following table to set unit IDs for switches.Make sure to set different unit IDs for different switches in an IRF fabric. Otherwise,FTM will automatically number the switches with the same unit ID.Table 1-3 Set a unit ID for a switchOperation Command DescriptionEnter systemview system-view —Set a unit ID forthe switchchange self-unit to { unit-id |auto-numbering }OptionalBy default, the unit ID of aswitch that belongs to no IRFfabric is 1. The unit ID of aswitch belonging to an IRFfabric is assigned by FTM. UnitID ranges from 1 to 8.Note:If you do not enable the fabric port, you cannot change the unit ID of the local switch.
