Solution - HP 5500 SI Troubleshooting Manual

Solution

To resolve the problem:
1. Verify that the number of member devices does not exceed the upper limit (nine for a 5500-EI IRF
fabric and four for a 5500-SI IRF fabric).
If you are adding a new member device to an existing IRF fabric, use the display irf command to
identify the number of member devices already in the IRF fabric.
2. Verify that the member ID of each member device is unique:
a. Execute the display irf configuration command to view the member ID of each member device.
b. If two member devices use duplicate IDs, assign a unique member ID to each member.
3. Verify that the IRF links are 10 Gbps:
a. Verify that the IRF physical ports are located on the rear 10-GE expansion interface cards. The
following are available 10-GE expansion interface cards:
−
−
−
−
−
b. Verify that the transceiver modules or cables for IRF connection are labeled with 10Gbps, XFP,
SFP+, or CX4.
c. Replace a transceiver module or cable if it is not for 10-Gbps connection.
4. 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 member device, and check the
IRF-Port1 and IRF-Port2 fields for IRF port bindings.
b. Verify the following items:
−
−
−
c. If there are binding errors or connection inconsistencies, reconfigure the IRF port bindings or
reconnect the physical IRF ports.
5. Verify that all IRF links are up:
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 interface command, and
then check the current state field.

Single-port 10G XFP interface card
2-port 10G XFP interface card
Short-haul 2-port 10G CX4 interface card
2-port 10G SFP+ interface card
2-port 10-GE interface card
The physical ports on the same expansion interface card are bound to the same IRF port.
When you are facing the rear panel, the physical ports bound to IRF-port 1 are on the left
and the physical ports bound to IRF-port 2 are on the right.
The physical IRF connections are consistent with the IRF port bindings.
If all physical ports bound to the IRF port are down, bring them up.
If the IRF port has at least one physical port in up state, go to step c.
