Configuring Basic Irf Settings; Connecting The Physical Irf Ports - H3C S5800-EI Series Installation Manual

Connecting the IRF member switches in a ToR solution
You can install IRF member switches in different racks side by side to deploy a top of rack (ToR)
solution.
Figure 40 shows an example for connecting top of rack IRF member switches by using SFP+/QSFP+
transceiver modules and optical fibers. The topology is the same as
Figure 40 ToR cabling

Configuring basic IRF settings

After you install the IRF member switches, power on the switches, and log in to each IRF member
switch (see H3C S5800-EI Switch Series Fundamentals Configuration Guide) to configure their
member IDs, member priorities, and IRF port bindings.
Follow these guidelines when you configure the switches:
•
Assign the master switch higher member priority than any other switch.
•
Bind physical ports to IRF port 1 on one switch and to IRF port 2 on the other switch. You
perform IRF port binding before or after connecting IRF physical ports depending on the
software release.
•
To bind the ports on an interface card to an IRF port, you must install the interface card first. For
how to install an interface card, see H3C S5800-EI Switch Series Interface Cards User Guide.
•
Execute the display irf configuration command to verify the basic IRF settings.
For more information about configuring basic IRF settings, see H3C S5800-EI Switch Series IRF
Configuration Guide.

Connecting the physical IRF ports

Use SFP+/QSFP+ cables or SFP+/QSFP+ transceiver modules and fibers to connect the IRF
member switches as planned.
Wear an ESD wrist strap when you connect SFP+/QSFP+ cables or SFP+/QSFP+ transceiver
modules and fibers. For how to connect them, see the installation guides for the transceiver modules
and cables.
