Solution
To resolve the problem:
1.
Verify that the number of member chassis does not exceed the upper limit (nine).
If you are adding new chassis to an existing IRF fabric, use the display irf command to identify the
number of member chassis already in the chassis.
2.
Verify that the member ID of each member chassis is unique:
a.
Execute the display irf configuration command to view the member ID of each chassis.
b.
If two member chassis use duplicate IDs, assign a unique member ID to each member.
3.
Verify that the physical IRF links are connected correctly:
IMPORTANT:
When you connect two neighboring IRF members, you must connect the physical ports of IRF-port 1
on one member to the physical ports of IRF-port 2 on the other.
a.
Execute the display irf configuration command on each member chassis, and check the
IRF-Port1 and IRF-Port2 fields for IRF port bindings.
b.
Verify that the physical IRF connections are consistent with the IRF port bindings.
c.
If there are inconsistencies, reconfigure the IRF port bindings or reconnect the physical IRF
ports.
4.
Verify that IRF links are 10 Gbps:
a.
Verify that the transceiver modules or cables for IRF connection are labeled with 10Gbps or
SFP+.
b.
Replace a transceiver module or cable if it is not for 10 Gbps connection.
5.
Verify that all IRF links are up:
a.
Execute the display irf topology command, and then check the Link field.
b.
If the Link field for an IRF port displays DOWN, execute the display interface command, and
then check the current state field.
−
If all physical ports bound to the IRF port are down, bring them up.
−
If the IRF port has at least one physical port in up state, proceed to the next step.
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.
6.
Verify that all member chassis 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 chassis to the same version.
