Configuring basic IRF settings

After you install the IRF member switches, power on the switches, and log in to each IRF member
switch (see the fundamentals configuration guide for your switch) to configure their member IDs,
member priorities, and IRF port bindings.
Follow these guidelines when you configure the neighboring 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.
Execute the irf-port-configuration active command to activate the IRF port configuration.
Execute the display irf configuration command to verify the basic IRF settings.
For more information about configuring basic IRF settings, see the IRF configuration guide for your

Connecting the physical IRF ports

Connect the IRF member switches as planned.
Wear an ESD wrist strap when you connect the physical IRF ports. For how to connect them, see
Pluggable SFP/SFP+/XFP Transceiver Modules Installation Guide.

Accessing the IRF fabric to verify the configuration

To verify the basic functionality of the IRF fabric after you finish configuring basic IRF settings and
connecting IRF ports:
Log in to the IRF fabric through the console port of any member switch.
Create a Layer 3 interface, assign it an IP address, and make sure the IRF fabric and the
remote network management station can reach each other.
Use Telnet, web or SNMP to access the IRF fabric from the network management station.
See the fundamentals configuration guide for your switch.
Verify that you can manage all member switches as if they were one node.
Display the running status of the IRF fabric by using the commands in the table bellow.
Display information about the IRF fabric.
Display all members' configurations that take
effect after switch reboots.
Display topology information about the IRF
To avoid IP address collision and network problems, configure at least one multi-active detection
(MAD) mechanism to detect the presence of multiple identical IRF fabrics and handle collisions. For
more information about MAD detection, see the IRF configuration guide for your switch.
