Solution
To resolve the issue:
1.
Verify that the number of member devices does not exceed 9.
If you are adding a new member device to an existing IRF fabric or merging IRF fabrics, use the
display irf
command to identify the number of member devices in the IRF fabrics. If the total
number of member devices exceeds the upper limit, the IRF setup will fail.
2.
Verify that the member ID of each member device is unique:
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 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
b.
member device, and check the
IRF-Port1
and
IRF-Port2
fields for IRF port bindings.
c.
Verify that the physical IRF connections are consistent with the IRF port bindings.
d.
If there are binding errors or connection inconsistencies, reconfigure the IRF port bindings
or reconnect the physical IRF ports.
4.
Verify that the IRF links meet the requirements.
For information about the interfaces that can be used as IRF physical interfaces, see the switch
installation guide or the IRF configuration in the virtual technologies configuration guide for your
switches. In addition, follow these restrictions and guidelines:
{
Typically, a port must operate at its highest rate when it is used as an IRF physical interface.
However, if you connect a 10G rate autosensing Ethernet port to a 5G rate autosensing
Ethernet ports, the 10G rate autosensing Ethernet port will operate at 5 Gbps.
{
The breakout interfaces of a QSFP+ or OSFP28 port cannot be used as IRF physical
interfaces.
{
Ports on the LSPM4G4T6P module cannot be used as IRF physical interfaces.
When you select transceiver modules or cables, follow these restrictions and guidelines:
{
Ethernet ports that operate at different rates have different requirements for cables or
transceiver modules. For more information, see the switch installation guide.
{
The cable or transceiver module for an IRF physical interface must match the rate of the
interface.
{
If transceiver modules and fibers are used, the transceiver modules at the two ends of an
IRF link must be the same type.
5.
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
ports bound to the IRF port.
