Solution - HPE FlexNetwork 10500 SERIES Troubleshooting Manual

Solution

To resolve the problem:
1. Verify that the number of member chassis in the IRF fabric does not exceed the upper limit.
The upper limit varies by software version and depends on the IRF mode. Execute the display
version command to identify the software version of the IRF fabric.
If the member chassis upper limit is reached for the software version, you cannot add new

chassis to the IRF fabric.
If the member chassis upper limit is not reached for the software version, execute

the display irf command to identify the IRF mode of the IRF fabric. Verify that the member
chassis upper limit is not reached for the IRF mode.
For more information about the upper limit, see HPE FlexNetwork 10500 Switch Series Virtual
Technologies Configuration Guide for the software version.
2. Verify that the chassis is a 10500 switch.
The 10500 switches can form an IRF fabric only with devices in the same series.
3. Verify that the chassis is operating in IRF mode:
a. Execute the display interface brief command to verify that the physical port numbers on
the chassis have changed from three segments to four segments. In IRF mode, the member
ID is added to physical port numbers as the first segment (for example, Ten-GigabitEthernet
1/4/0/1).
b. Execute the chassis convert mode irf command to change the operating mode to IRF.
4. Verify that the chassis is operating in the same IRF mode as the IRF fabric:
a. Execute the display irf command and check the IRF mode field.

b. If the chassis is operating in an IRF mode different than the IRF fabric, execute the irf mode
command to change the IRF mode for the chassis. The changed mode will take effect after
a reboot.
5. Verify that the member ID of the chassis does not conflict with any member chassis in the IRF
fabric:
a. Execute the display irf command to view member IDs.
b. If the member ID of the chassis is not unique, use the irf member renumber command to
assign a new member ID to the chassis.
6. 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.
