Cross-Chassis Packet Loss Problem; Symptom; Solution; Irf Split - HP HSR6600 Troubleshooting Manual

5. In probe view, execute the display hardware internal wanirf ibd debugging chassis
chassis-number slot slot-number all on command to collect IBD packet debugging information for
IRF physical interfaces. Verify that the packet format and contents are correct.
6. If the peer IRF physical interfaces can send and receive IBD packets, execute the command in step
3. Use the command to verify that the local traffic can be forwarded to the destination card in the
neighboring device.
7. In probe view, execute the display hardware internal module interface-name statistics command
to check the outgoing interface statistics for each IRF physical interface. If the statistics are incorrect,
contact HP Support to identify the cause.

Cross-chassis packet loss problem

Symptom

Packet loss occurs for cross-chassis traffic.

Solution

To resolve the problem:
1. Use the methods described in
issue and remove the issue.
2. If the problem persists, contact HP Support.

IRF split

Symptom
An IRF fabric splits. An IRF fabric splits if the active MPUs on the member devices do not receive packets
from each other within 20 seconds.
Solution
To resolve the problem:
1. Execute the display irf link command to verify that the IRF links are up. If an IRF link is down, check
the cable, or the transceiver modules and fiber, and identify whether the cards that provide the IRF
physical interfaces have rebooted.
2. In probe view, execute the display hardware internal wanirf portinfo chassis chassis-number slot
slot-number command to check the IRF physical interface status and outgoing interface information.
If any abnormalities occur, contact HP Support to identify the cause.
3. Execute the display cpu-usage command to check the CPU usage of MPUs and interface cards.
Verify that the CPUs are not overwhelmed.
4. In probe view, execute the display hardware internal wanirf ipc pkt-info chassis chassis-number
slot slot-number interface-type interface-number command to identify whether an IRF physical
