5. Verify that the two ends of an IRF link are operating at the same rate.
If you are using transceiver modules and fibers, verify that the transceiver modules at the two
ends of an IRF link are the same type. If the transceiver modules are not the same type, replace
them to be the same type.
6. Verify that all IRF links are up:
a. Execute the display irf topology command, and then check the Link field.
−
−
b. Execute the display irf link command, and then check the Status field of the physical
interfaces bound to the IRF port.
−
−
c. Save the configuration, and then execute the irf-port-configuration active command in
system view to activate the IRF port configuration.
IMPORTANT:
Activating IRF port configuration requires a reboot. To prevent configuration loss, you must
save the configuration before you execute the irf-port-configuration active command.
7. Verify that all member devices use the same software version:
a. Execute the display version command to identify the software version of each member
device.
b. Upgrade the software of all member devices to the same version.
NOTE:
Typically, the irf auto-update enable command can automatically synchronize a member
device with the software version of the master device. However, the synchronization might fail
when the gap between the software versions is too large. For more information, see the release
notes.
8. Execute display commands to verify that all member devices use the same settings for the
following features:
System operating mode (set by using the system-working-mode command).

Hardware resource mode for the MAC address table, ARP and ND tables, and routing

tables (set by using the hardware-resource switch-mode command).
Enhanced ECMP mode (set by using the ecmp mode enhanced command).

Support for the IPv6 routes with prefixes longer than 64 bits (set by using the

hardware-resource routing-mode ipv6-128 command).
Enabling status of packet loss prevention for OpenFlow forwarding (set by using the

openflow lossless enable command).
VXLAN hardware resource allocation mode (set by using the hardware-resource vxlan

command).
9. If the issue persists, contact H3C Support.

This section lists the commands that you might use for troubleshooting IRF.
If the Link field for each IRF port does not display DOWN, go to step 7.
If the Link field for an IRF port displays DOWN, go to step b.
If the field displays DOWN or ADM (administratively down) for all the physical interfaces,
remove the link failures or use the undo shutdown command to bring up the
administratively down physical interfaces.
If the field displays UP for at least one of the physical interfaces, go to step c.
