6.
If the peer IRF physical interfaces can send and receive IBD packets, execute the command in
step
. Use the command to verify that the local traffic can be forwarded to the destination slot.
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 H3C 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 "
Cross-chassis traffic forwarding failure
" to identify the packet
loss issue and remove the issue.
2.
If the problem persists, contact H3C Support.
IRF split
Symptom
An IRF fabric splits. An IRF fabric splits if 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 slots 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 H3C Support to identify the
cause.
3.
Execute the
display cpu-usage
command to check the CPU usage. 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 interface has IPC packet loss statistics. If an IRF physical interface has packet
loss statistics, contact H3C Support to identify the cause.
5.
In probe view, execute the
display hardware internal wanirf ipc debugging chassis
chassis-number
slot
slot-number
all on
command to check IPC packet debugging information
for IRF physical interfaces. Verify that the packet format and contents are correct.
6.
In probe view, execute the
display hardware internal wanirf ipc sendpkt chassis
chassis-number
slot
slot-number
unicast chassis chassis-number
slot
slot-number
pkt-length pkt-number
command.
