Page 9: Setting Up An Irf Fabric
Setting up an IRF fabric Overview H3C Intelligent Resilient Framework (IRF) technology virtualizes multiple physical devices at the same layer into one virtual fabric to provide data center class availability and scalability. IRF virtualization technology offers processing power, interaction, unified management, and uninterrupted maintenance of multiple devices. -
Page 10: Network Topology
Network scalability and resiliency—Processing capacity of an IRF fabric equals the total • processing capacities of all the members. You can increase ports, network bandwidth, and processing capacity of an IRF fabric simply by adding member devices without changing the network topology. - Page 11 IRF domain ID One IRF fabric forms one IRF domain. IRF uses IRF domain IDs to uniquely identify IRF fabrics and prevent IRF fabrics from interfering with one another. As shown in Figure 2, IRF fabric 1 contains Device A and Device B, and IRF fabric 2 contains Device C and Device D.

Page 12: Interface Naming Conventions
Figure 4 IRF merge Member priority Member priority determines the possibility of a member device to be elected the master. A member with higher priority is more likely to be elected the master. Interface naming conventions An interface is named in the chassis-number/slot-number/port-index format. chassis-number—IRF member ID of the switch. - Page 13 <Master> dir Directory of flash: 0 -rw- 43548660 Jan 01 2011 08:21:29 system.ipe 1 drw- - Jan 01 2011 00:00:30 diagfile 2 -rw- 567 Jan 02 2011 01:41:54 dsakey 3 -rw- 735 Jan 02 2011 01:42:03 hostkey 4 -rw- 36 Jan 01 2011 00:07:52 ifindex.dat 5 -rw- 0 Jan 01 2011 00:53:09...

Page 14: Configuration Synchronization Mechanism
Configuration synchronization mechanism IRF uses a strict running-configuration synchronization mechanism. In an IRF fabric, all devices obtain and run the running configuration of the master. Configuration changes are automatically propagated from the master to the remaining devices. The configuration files of these devices are retained, but the files do not take effect. -
Page 15: Mad Mechanisms
Collision handling When MAD detects a multi-active collision, it sets all IRF fabrics except one to the Recovery state. The fabric that is not placed in Recovery state can continue to forward traffic. The Recovery-state IRF fabrics are inactive and cannot forward traffic. LACP MAD uses the following process to handle a multi-active collision: Compares the number of members in each fabric. - Page 16 Table 1 Comparison of MAD mechanisms Advantages Disadvantages Application scenario mechanism Link aggregation is used between the IRF fabric • Detection speed is fast. and its upstream or Requires an intermediate downstream device. • Does not require LACP MAD device that supports MAD-dedicated physical For information about extended LACP for MAD.
- Page 17 The intermediate device must be a device that supports extended LACP for MAD. • The IRF member devices send extended LACPDUs that convey a domain ID and an active ID. The intermediate device transparently forwards the extended LACPDUs received from one member device to all the other member devices.
- Page 18 NOTE: The MAD addresses identify the member devices and must belong to the same subnet. • Of all management Ethernet ports on an IRF fabric, only the master's management Ethernet port is • accessible. Figure 6 shows a typical BFD MAD scenario that uses an intermediate device. Figure 7 shows a typical BFD MAD scenario that does not use an intermediate device.
- Page 19 If an intermediate device is used, connect each IRF member device to the intermediate device. Run the spanning tree feature between the IRF fabric and the intermediate device. In this situation, data links can be used. If an intermediate device is not used, connect each IRF member device to all other member devices.

See Fundamentals Configuration Guide. Configuration backup H3C recommends that you back up the next-startup configuration file on a device before adding the device to an IRF fabric as a subordinate. A subordinate device's next-startup configuration file might be overwritten if the master and the subordinate use the same file name for their next-startup configuration files. - Page 23 Configuring IRF link load sharing mode: Configuring the global load sharing mode Configuring a port-specific load sharing mode (Optional.)

Page 24: Planning The Irf Fabric Setup
Planning the IRF fabric setup Consider the following items when you plan an IRF fabric: • Hardware compatibility and restrictions. IRF fabric size. • Master device. • IRF physical interfaces. • Member ID and priority assignment scheme. • • Fabric topology and cabling scheme. For more information about hardware and cabling, see the switch installation guide. -
Page 25: Specifying A Priority For Each Member Device
Specifying a priority for each member device IRF member priority represents the possibility for a device to be elected the master in an IRF fabric. The higher the priority, the higher the possibility. A change to member priority affects the election result at the next master election. However, it does not cause an immediate master re-election. -

Page 30: Enabling Software Auto-Update For Software Image Synchronization
NOTE: IRF fabrics that have the same bridge MAC address cannot merge. If you use the removed bridge MAC owner as the master device in a new fabric, the bridge MAC of the new fabric is the same as the old fabric. -
Page 31: Configuration Prerequisites
When you add a device to the IRF fabric, software auto-update compares the startup software images of the device with the current software images of the IRF master. If the two sets of images are different, the device automatically performs the following operations: Downloads the current software images of the master. -
