The S7500E switches support multi-card link aggregation for IRF ports. You can bind up to eight physical
ports to one IRF port.

Configuring 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.
After you install the IRF member switches, power on the switches, and log in to each IRF member switch
(see "
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 might 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.
For more information about configuring basic IRF settings, see H3C S7500E Series Ethernet Switches IRF
Configuration Guide.
Connecting the physical IRF ports
Follow these guidelines when selecting transceiver modules and cables:
•
Use XFP transceiver modules and fibers to connect XFP ports.
•
Use SFP+ transceiver modules and fibers for long-haul connection, or use SFP+ cables to connect
SFP+ ports for short-haul connection.
•
Use CFP transceiver modules and fibers to connect CFP ports.
•
When connecting XFP/SFP+/CFP ports, connect the transmit port of an XFP/SFP+/CFP transceiver
module at one end to the receive port of an XFP/SFP+/CFP transceiver module at the other end.
•
Use QSFP+ transceiver modules and fibers for long-haul connection, or use QSFP+ cables to
connect QSFP+ ports for short-haul connection.
