1-15z Member ID change takes effect at the reboot of a device.z To view the current member ID of a device, use the display irf configuration command. Themember ID takes effect at the device reboot.z Member IDs are not only used to identify members of an IRF virtual device, but also used toidentify the port configurations on different members. Therefore, member ID change may causedevice configuration changes or even losses, so change member ID with caution. For example,three members (of same device model) with the member IDs of 1, 2 and 3 are connected to an IRFport. Assume that each member has several ports: change the member ID of device 2 to 3, changethat of device 3 to 2, reboot both devices, and add them into the IRF virtual device again. Thendevice 2 uses the original port configurations of device 3, and device 3 uses those of device 2.Configuring IRF PortsConfiguring the correspondence between an IRF port and a physical IRF portIRF can run on a device only when IRF ports are bound with physical IRF ports.For how to bind IRF ports and physical IRF ports, see Correspondence between an IRF port and aphysical IRF port.Follow these steps to configure IRF ports:To do… Use the command… RemarksEnter system view system-view —Enter physical IRF port view interface interface-typeinterface-number —Shut down the port shutdown RequiredReturn to system view quit —Create an IRF port and enter IRFport view irf-port member-id/port-numberRequiredNo IRF port is created on thedevice by default.If the IRF port is already created,you can use this command toenter IRF port view.Bind a physical IRF port to theIRF portport group interface interface-typeinterface-number [ mode { enhanced| normal } ]RequiredBy default, no physical IRF portis bound to the IRF port.Return to system view quit —Enter physical IRF port view interface interface-typeinterface-number —Bring up the port undo shutdown RequiredReturn to system view quit —Save the current configuration save Required
