Page 9: Irf Overview
This book describes IRF concepts and guides you through the IRF setup procedure. Hardware compatibility An H3C S5130-EI switch can form an IRF fabric only with devices in the same series. IRF benefits IRF provides the following benefits: Simplified topology and easy management—An IRF fabric appears as one node and is accessible... -
Page 10: Basic Concepts
Figure 1 IRF application scenario Basic concepts This section describes the basic concepts you might encounter when you work with IRF. IRF member roles IRF uses two member roles: master and standby (called subordinate throughout the documentation). When devices form an IRF fabric, they elect a master to manage and control the IRF fabric, and all the other devices back up the master. -
Page 11: Irf Physical Interface
To use an IRF port, you must bind a minimum of one physical interface to it. The physical interfaces assigned to an IRF port form an aggregate IRF link automatically. An IRF port goes down only if all its IRF physical interfaces are down. -
Page 12: Irf Split
IRF split IRF split occurs when an IRF fabric breaks up into two or more IRF fabrics because of IRF link failures, as shown in Figure 3. The split IRF fabrics operate with the same IP address and cause routing and forwarding problems on the network. -
Page 13: File System Naming Conventions
On the standalone switch Sysname, GigabitEthernet 1/0/1 represents the first port on the device. • Set its link type to trunk, as follows: <Sysname> system-view [Sysname] interface gigabitethernet 1/0/1 [Sysname-GigabitEthernet1/0/1] port link-type trunk • On the IRF fabric Master, GigabitEthernet 3/0/1 represents the first fixed port on member device 3. -

In this example, the current working path is the root directory of the flash on member device 3. -
Page 15: Irf Multi-Active Detection
Two members are considered to start up at the same time if the difference between their startup times is equal to or less than 10 minutes. For these members, the next tiebreaker applies. Member with the lowest CPU MAC address. For the setup of a new IRF fabric, the subordinate devices must reboot to complete the setup after the master election. -
Page 16: Lacp Mad
In contrast, BFD MAD, ARP MAD, and ND MAD do not compare the number of members in fabrics. These MAD mechanisms use the following process to hand a multi-active collision: Compare the member IDs of the masters in the IRF fabrics. Set all fabrics to the Recovery state except the one that has the lowest numbered master. -
