If the upper limit is reached, you cannot add new member devices to the IRF fabric. The upper
limit varies by software version. For information about the upper limit, see IRF configuration in
the configuration guides for your software version.
2.
Verify that the device is the same model as the member devices in the IRF fabric.
The H3C S6890 switches must be the same model to form an IRF fabric.
3.
Verify that the member ID of the device is unique in the IRF fabric:
a.
Execute the
display irf
command to view member IDs.
b.
Execute the
irf member renumber
command to assign a new member ID to the device
if necessary.
4.
Verify that the physical IRF links are connected correctly:
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 inconsistencies, reconfigure the IRF port bindings or reconnect the IRF physical
interfaces.
5.
Verify that all IRF links are up for the device:
IMPORTANT:
An IRF port is a logical interface that connects IRF member devices. To use an IRF port, you
must bind a minimum of one physical interface to it. The physical interfaces assigned to an IRF
port automatically form an aggregate IRF link. An IRF port goes down when all its IRF physical
interfaces are down.
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 irf link
command.
c.
Check the
Status
field for each physical interface bound to the IRF port. If the field displays
ADM
, execute the
undo shutdown
command to bring up the interface. If the field displays
DOWN
, check the transceiver modules or cables for connectivity issues. When you select
transceiver modules and cables, follow these restrictions and guidelines:
−
Use SFP+ transceiver modules and fibers to connect SFP+ ports for a long-distance
connection, or use SFP+ DAC cables to connect SFP+ ports for a short-distance
connection.
−
Use QSFP28 or QSFP+ transceiver modules and fibers to connect QSFP28 ports for a
long-distance connection, or use QSFP28 or QSFP+ DAC cables to connect QSFP28
ports for a short-distance connection.
−
The transceiver modules at the two ends of an IRF link must be the same type.
NOTE:
Supported transceiver modules and cables might vary depending on the software version
and device model. For more information, see the most recent installation guide.
6.
Verify that the device is running the same software version as the IRF fabric:
a.
Execute the
display version
command to identify the software version.
b.
Upgrade the device to use the same software version as the IRF fabric.
