a.
Execute the
display irf
command to view the member ID of each member device.
b.
Assign a unique member ID to each member.
−
If you are adding a new member device to an existing IRF fabric, assign the member
device a member ID that is not being used in the IRF fabric.
−
If you are merging IRF fabrics, make sure each member device in these IRF fabrics has
a unique member ID.
3.
Verify that the IRF port bindings and physical IRF link connections are correct:
IMPORTANT:
When you connect two neighboring IRF members, you must connect the physical interfaces of
IRF-port 1 on one member to the physical interfaces of IRF-port 2 on the other.
a.
Execute the
display irf configuration
command on each member device, 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 binding errors or connection inconsistencies, reconfigure the IRF port bindings
or reconnect the IRF physical interfaces.
4.
Verify that the IRF links are 10 Gbps or 40 Gbps:
a.
Verify that the transceiver modules and fibers or DAC cables for IRF connection are labeled
with
10Gbps
,
SFP+
,
40Gbps
, or
QSFP+
.
b.
Replace a transceiver module, fiber, or DAC cable if it is not for 10-Gbps or 40-Gbps
connection.
5.
(Optional.) Verify that transceiver modules at the two ends of an IRF link are the same type if
you are using SFP+ or QSFP+ transceiver modules and fibers.
If the transceiver modules are not the same type, replace them to be the same type.
Skip this step if you are using SFP+ or QSFP+ DAC cables to connect IRF member devices.
6.
Verify that all IRF links are up:
a.
Execute the
display irf topology
command, and then check the
Link
field.
−
If the
Link
field for each IRF port does not display
DOWN
, go to step
−
If the
Link
field for an IRF port displays
DOWN
, go to step
b.
Execute the
display irf link
command, and then check the
Status
field of the physical
interfaces bound to the IRF port.
−
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 interfaces.
−
If the field displays
UP
for a minimum of one of the physical interfaces, go to 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.
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. As a best practice,
upgrade a lower version to a higher version.
