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. Because the configuration of some parameters takes effect after device reboot, you
are recommended to first configure parameters, power off the devices, connect devices physically,
power on the devices, and finally the devices will join in the IRF virtual device automatically. After an
IRF virtual device is formed, you can configure and manage the IRF virtual device by logging in to any
device in the IRF virtual device. The operations you make take effect on the master, and will be applied
to the member devices in the IRF virtual device. For easy fault location and device maintenance, the
Switch 4800G series provide slave view, where you can execute the display, terminal, and debug
commands.
Complete the following tasks to configure IRF:
Configuring IRF Virtual
Device
Connect the physical IRF ports of devices by using IRF cables (a ring connection is recommended) or fibers,
and then power on the devices.
Accessing an IRF Virtual
Device

Configuring IRF Virtual Device

Configuring IRF Ports

IRF ports are logical. IRF can be enabled on a device only after the IRF ports are configured (in other
words, the IRF ports are bound to physical IRF ports).
For how to bind the IRF port and physical IRF port(s) on a Switch 4800G series, see
between an IRF port and a physical IRF
