Irf Configuration Task List; Configuring Irf Ports - HP 4800G Series Configuration Manual

IRF maintenance
In an IRF, direct neighbors exchange hello packets periodically (the period is 200 ms). Without receiving
any hello packet from a direct neighbor for ten periods, a member considers that the hello 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 Configuration Task List

Before configuring an IRF, 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 automatically. After an IRF is formed, you can
configure and manage the IRF by logging in to any device in the IRF. The operations you make take
effect on the master, and will be applied to the member devices in the IRF. For easy fault location and
device maintenance, the Switch 4800G provides slave view, where you can execute the display,
terminal, and debug commands.
Complete the following tasks to configure IRF:
IRF Configuration
Connect the physical IRF ports of devices by using IRF cables (a ring connection is recommended)
or fibers, and then power on the devices.

Configuring IRF Ports

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