Task 7. Assigning an IRF domain ID to the IRF fabric 8. Configuring a member switch description 9. Configuring IRF bridge MAC persistence 10. Enabling software auto-update for system software image synchronization 11. Setting the IRF link down report delay 12. Configuring MAD: { Configuring LACP MAD { Configuring BFD MAD { Configuring ARP MAD { Excluding a port from the shutdown action upon detection of multi-active collision { Recovering an IRF fabric Remarks This task is required for ARP MAD and LACP MAD. Optional. Optional. Optional. HP recommends enabling software auto-update to make sure system software image synchronization Optional. Required. MAD mechanisms are independent of one another. You can configure at least one MAD mechanism for an IRF fabric. Planning the IRF fabric setup Consider the following items when you plan an IRF fabric: • Hardware compatibility and restrictions • IRF fabric size • Master switch • IRF physical ports • Member ID and priority assignment scheme • Fabric topology and cabling scheme For more information about hardware and cabling, see the switch installation guide. Assigning a member ID to each IRF member switch CAUTION: In an IRF fabric, changing IRF member IDs might cause undesirable configuration changes and even data loss. Before you do that, back up the configuration and make sure you fully understand the impact on your network. For example, all member switches in an IRF fabric are the same model. If you swapped the IDs of any two members, their interface settings would also be swapped. By default, the member IDs of all switches are 1. To create an IRF fabric, you must assign a unique IRF member ID to each switch. Perform this task before the IRF fabric is formed. To prevent any undesirable configuration change or data loss, avoid changing member IDs after the IRF fabric is formed. 13
