Failure to forward packets
Symptom
An Ethernet interface on an intermediate router cannot forward packets.
Solution
To resolve the problem:
1.
Verify that the Ethernet interface can ping the directly connected device. If the ping operation
fails, see "
Failure to ping the directly connected device ."
2.
Use the
debugging ip packet
command to verify that the interface can transmit packets
correctly.
3.
Collect the following information for the interface:
{
Execute the
display hardware internal module
interface-name interface-number
statistics
command in probe view to collect the interface statistics.
{
Execute the
display hardware internal module
interface-name interface-number
status
command in probe view to collect the status information.
{
Execute the
display hardware internal module
interface-name interface-number
reg 1
command in probe view to collect the FPGA information.
{
Execute the
display hardware internal module
interface-name interface-number
reg 2
command in probe view to collect the MAC information.
{
Execute the
display hardware internal module
interface-name interface-number
reg 3
command in probe view to collect the PHY information.
4.
Contact H3C Support.
Packet dropping
Symptom
An Ethernet interface drops packets.
Solution
To resolve the problem:
1.
Determine whether the packets are dropped by the local end or the peer end by executing the
following commands to compare the rates of the two ends:
{
Execute the
display counters rate inbound interface
command on the local end
to view the inbound traffic rate statistics.
