physical interface. This command displays statistics about IPC packets sent and received by an
interface.
If the command does not display any packet statistics, verify that the
irf-port-configuration
active
command has been executed.
If the command displays packet loss statistics, contact H3C Support to identify the cause.
6.
In probe view, execute the
display hardware internal wanirf topoinfo
chassis
chassis-number
slot
slot-number
command to check the status of each slot that provides IRF
physical interfaces. Make sure a minimum of one slot is active. If no slot is active, contact H3C
Support to identify the cause.
7.
In probe view, execute the
display hardware internal wanirf portinfo chassis
chassis-number
slot
slot-number
command to collect the IRF physical interface status and
outgoing interface information. If any abnormalities occur, contact H3C Support to identify the
cause.
8.
In probe view, execute the
display hardware internal wanirf stm debugging chassis
chassis-number
slot
slot-number
all on
command. Use this command to collect the STM
packet debugging information on each slot that provides IRF physical interfaces. Send the
collected information to H3C Support to verify that the packet format and contents are correct.
9.
In probe view, execute the
display hardware internal wanirf stm pkt-info chassis
chassis-number
slot
slot-number
command to display STM packet statistics.
(SR6602-X routers.) Use this command to verify that STM packets can be forwarded from
one member device to the other member device.
(SR6600 and SR6600-X routers except for SR6602-X.) Use this command to verify that
STM packets can be forwarded from the active MPU on a member device to the active MPU
on the other member device.
10.
If the problem persists, contact H3C Support.
Cross-chassis traffic forwarding failure
Symptom
Traffic cannot be forwarded across chassis in an IRF fabric.
Solution
To resolve the problem:
1.
Verify that the device configuration is correct and the IRF ports are up.
2.
Execute the
display ip statistics chassis
chassis-number
slot
slot-number
command to verify
that the source slot has sent out the traffic successfully.
If the traffic forwarding fails, contact H3C Support to identify the cause.
3.
In probe view, execute the
display hardware internal ibd pkt-info chassis
chassis-number
slot
slot-number
verbose
command for the slots on the traffic forwarding path. Verify that traffic
from the source slot can be forwarded to the specified slots. If traffic forwarding fails, contact
H3C Support to identify the cause.
4.
In probe view, execute the
display hardware internal wanirf ibd pkt-info chassis
chassis-number slot
slot-number interface-type interface-number
command for each IRF
physical interface of the member devices. Use this command to verify that an IRF physical
interface can send and receive IBD packets. If a physical interface cannot send or receive
packets, contact H3C Support to identify the cause.
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.
