Page 6: Irf Configuration
IRF Overview Introduction Developed by 3Com, Intelligent Resilient Framework (IRF) provides a new method to connect multiple devices through physical IRF ports. Individual devices join to form a distributed device called IRF virtual device. IRF realizes the cooperation, unified management, and non-stop maintenance of multiple devices. -
Page 7: Application
Application As shown in Figure 1-1, a master and a slave form an IRF virtual device, which is a single device to the upper and lower layer devices. Figure 1-1 IRF networking IP network IP network Slave Master Equal to IRF virtual device IRF link Basic Concepts... -
Page 8: Working Process
IRF virtual device merge As shown in Figure 1-2, two IRF virtual devices operate independently and steadily. Connect them physically and perform necessary configurations to make them form one IRF virtual device, and this process is called IRF virtual device merge. Figure 1-2 IRF virtual device merge IRF virtual device partition As shown in... - Page 9 Short-haul dual-port 10 GE CX4 interface module Dual-port 10 GE SFP+ interface module For more information about an interface module, refer to its user manual. You can connect physical IRF ports of the Switch 4800G series with either the CX4/SFP+ dedicated cables or fibers according to the interface type on the interface module.
- Page 10 Figure 1-5 IRF virtual device physical connection IRF topology An IRF virtual device typically adopts daisy chain connection or ring connection, as shown in Figure 1-6. A daisy chain connection is mainly used in a network where member devices are distributedly located.
- Page 11 You need to specify the correspondence between an IRF port and physical IRF port(s) through command line. When you specify that an IRF port is bound to one physical IRF port, the serial number of the physical IRF port bound to IRF port 1 must be smaller than that of the physical IRF port bound to IRF port 2;...
- Page 12 If only one single-port interface module is installed, the device can be used only as Switch B or Switch C in Figure 1-7, that is, the device should be at either end of a bus connection. In this situation, because only one IRF port is needed on Switch B or Switch C, IRF-port 2 or IRF-port 1 can be bound to any physical port on the device.

Page 13: Topology Collection
Figure 1-10 Correspondence in aggregate mode for two interface modules Because the two physical IRF ports bound to an aggregate IRF port must be located on the same interface module, two IRF ports (that is, two aggregate IRF ports) can only be bound to the two physical IRF ports on each of the two interface modules respectively (as shown in Figure 1-10). -

the rules below, in the order specified. If the first rule does not apply, a second rule is tried, and so on, until the only winner is found. The current master, even if a new member has a higher priority. (When an IRF virtual device is being formed, and all member devices consider themselves as the master, so this principle is skipped) A member with a higher priority. - Page 15 connection, slaves connected to IRF port 1 of the master are numbered from near to far, and then those connected to IRF port 2 of the master are numbered the same way; for a ring connection, the slave connected to IRF port 1 of the master is numbered first, then, other slaves are numbered from near to far, and the slave connected to IRF port 2 of the master is numbered the last.

packets timed out, and the IRF isolates the expired device in the topology and updates its topology database. When an IRF port of a member becomes down, the member broadcasts the information to all the other members immediately. If the IRF port of the master is down, an election is triggered. IRF Virtual Device Configuration Task List Before configuring an IRF virtual device, you need to define the roles and functions of all the members for better planning. -

The above configuration takes effect after the reboot of the device. An IRF port that is bound with multiple physical IRF ports is an aggregation IRF port, which increases the bandwidth and reliability on the IRF port. -

device, the packet is sent to this device; otherwise, the packet is discarded. Therefore, a bridge device on your network must have a unique bridge MAC address. If two devices on your network have the same bridge MAC addresses, bridge MAC address collision occurs and the communication fails. An IRF virtual device communicates with external networks as a single device;... -
Page 23: Setting The Delay Time For The Link Layer To Report A Link-Down Event
If auto upgrade of boot file is enabled, as soon as a device is added into an IRF virtual device, the IRF virtual device compares its software version with that of the master. If the versions are not consistent, the device automatically downloads the boot file from the master, reboots with the new boot file, and joins the IRF virtual device again. -
Page 24: Accessing An Irf Virtual Device
Do not set the delay time to a very long time; otherwise, the IRF virtual device will not be aware of the IRF topology changes in time and thus the service will be recovered slowly. Accessing an IRF Virtual Device Accessing the Master Access an IRF virtual device in either of the following two ways: Local login: Log in through the AUX or console port of a member device. -
