5.
Verify that the physical IRF links meet the rate requirements:
a.
Verify that the correct transceiver modules or cables are used:
−
Use Category 6A (or above) twisted-pair cables to connect 10GBase-T Ethernet ports in
a short distance.
−
Use SFP+ DAC cables to connect SFP+ ports in a short distance.
−
Use SFP+ transceiver modules and fibers to connect SFP+ ports in a long distance.
−
Use QSFP+ or QSFP+ to SFP+ DAC cables to connect QSFP+ ports in a short distance.
−
Use QSFP+ transceiver modules and fibers to connect QSFP+ ports in a long distance.
−
Use QSFP28 DAC cables to connect QSFP28 ports in a short distance.
−
Use QSFP28 transceiver modules and fibers to connect QSFP28 ports in a long
distance.
b.
Verify that 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. Perform this
step if transceiver modules are used for IRF connection. Skip this step if you are using 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
7
.
−
If
the
Link
field for an IRF port displays
DOWN
, go to step
b
.
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 physical interfaces.
−
If the field displays
UP
for at least one of the physical interfaces, go to step
c
.
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.
The mode is set by using the
system-working-mode
command.
{
Table capacity mode.
