Identifying the physical IRF ports on the member switches
Determine which 10-GE ports to use for IRF connection depending on the bandwidth and reliability
requirements.
The S7500E series switches support link aggregation and cross-card aggregation for IRF ports. You can
bind up to eight physical ports to one IRF port.
Installing IRF member switches
Follow these steps to install IRF member switches:
Step Reference
Prepare the installation site Chapter 2 “Preparing for installation”
Mount the IRF member switches to racks Chapter 3 “Installing the switch”
Install modules on IRF member switches Chapter 4 “Installing modules”
Configuring basic IRF settings
After you install the IRF member switches, power on the switches, and log in to each IRF member switch
(see Chapter 6 “Connecting your switch to the network”) to configure their member IDs, member
priorities, and IRF port bindings.
Follow these guidelines when you configure the switches:
• You may need to first change the operating mode of the switches to IRF mode depending on your
software release.
• 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.
• Execute the display irf configuration command to verify the basic IRF settings.
CAUTION:
If one or two LSQ1SRP2XB (LSQM1SRP2XB) SRPUs are used, the switch automatically creates one virtual
LPU slot for each SRPU slot, and the LPU slot numbers are higher than the largest physical LPU slot number.
To bind the XFP ports on one SRPU to an IRF port, you must access the virtual LPU for the SRPU. You can
use the display device command to display information about the virtual LPU slots.
For more information about configuring basic IRF settings, see the H3C S7500E Series Ethernet Switches
IRF Configuration Guide.
Connecting the physical IRF ports
Power off the switches and connect their physical IRF ports.
• Use XFP transceiver modules and fibers to connect 10-Gigabit XFP ports.
• You can use SFP+ transceiver modules and fibers to connect 10-Gigabit SFP+ ports over a long or
short distance, and use SFP+ cables to connect 10-Gigabit SFP+ ports over a relatively short
distance.
