1-15z The above configuration takes effect after the reboot of the device.z AN IRF port that is bound with multiple physical IRF ports is an aggregation IRF port, whichincreases the bandwidth and reliability on the IRF port. If you specify multiple physical IRF portswith the port-list argument, you can configure an aggregation IRF port. You can configure at mosttwo physical IRF ports as an aggregation IRF port for an S5120-EI series switch, and you can onlyaggregate physical IRF ports 1 and 2, and physical IRF ports 3 and 4.z The irf-port-id argument represents the IRF port number. The port-list argument represents thephysical IRF port number. For the correspondence of IRF ports, refer to Correspondence betweenan IRF port and a physical IRF port.z When you insert a one-port interface module into the slot on the rear panel, if the interface moduleis in slot 1, the port on it will be numbered 1; and if the interface module is in slot 2, the port on it willbe numbered 3.Setting a Member ID for a DeviceThe member ID of a device defaults to 1. During the establishment of an IRF, when the devices thatform the IRF have duplicated member IDs, the member ID of the master is decided first, and then themember IDs of slaves are decided one by one according to their distances to the master, that is, thenearest slave gets the smallest available ID, and the nearer slave gets the smaller available ID, and soforth; after the IRF is established, if the newly added device and another member have duplicated IDs,the IRF system assigns the smallest available ID for the new member. You can also set the member IDsaccording to network planning.For a device that is already in an IRF, you can use commands in Table 1-1 to modify the member ID ofthe device, and this modification will be effective after the reboot of the device.For a device that is not in an IRF, you are recommended to set its member ID in the following way:1) Plan the member IDs in advance. You can view the member IDs of an IRF, and find out an unusedID for the new device.2) Log in to the device to be added into the IRF, and change its member ID to the unused ID found outin step 1.3) Save the current configuration. Power off the device, connect the device with IRF cables and powerit on. Use the configuration introduced in this section to enable IRF on the device and add it into theIRF.Table 1-1 Set a member ID for a deviceTo do… Use the command… RemarksEnter system view system-view —Set a member ID for a device irf member member-id renumbernew-idOptionalThe member ID of a devicedefaults to 1
