Solution
To resolve the issue:
1.
Examine the packet statistics of the port:
a.
(Optional.) Use the
reset counter interface
command to clear the packet statistics of
the port.
This command resets the values of each statistical field to 0, so that you can view the
statistics changes more clearly.
b.
Determine whether the ports at both ends are always up, and use the
display interface
command to determine whether the number of outgoing packets is accumulating.
c.
Determine whether the number of error packets is accumulating.
2.
Verify that the port configurations do not affect packet sending:
a.
Use the
display interface brief
command to verify that the port configurations are
correct.
The port configurations include the duplex mode, speed, port type, and VLAN
configurations of the ports at both ends of the link.
