l
If the Internet access is low, go to
Step 4
Check whether unknown traffic is occupying the bandwidth on the ONU.
1.
Ensure that the user is not accessing the Internet. Run the
display port statistics portid
command to query the statistics of the Ethernet port multiple times (recommended: five
times). The query interval is 20s.
l
If the upstream or downstream traffic increases rapidly, unknown traffic is occupying
the bandwidth. Go to
.
l
If the upstream or downstream traffic does not increase, go to
.
NOTE
Normally, the query results should be similar when the user is not accessing the Internet.
l
Number of transmitted octets
: Indicates the current downstream traffic of the user.
l
Number of received octets
: Indicates the current upstream traffic of the user.
2.
Use packet-capturing software, such as Ethereal, to capture packets on the user's PC,
confirm the known traffic source, and then eliminate the unknown traffic source. You can
eliminate the unknown traffic source by checking whether the PC sending the unknown
traffic is infected with viruses. Then, check whether the Internet access rate is restored.
l
If the Internet access rate is restored, go to
.
l
If the Internet access is not restored, go to
Step 5
Check the maximum rate configured for the user.
1.
Run the
display service-port
command to query the indexes of the traffic profiles in the
receive and transmit directions configured for the service port.
2.
Run the
display traffic table ip
command to query the corresponding traffic profile. Then,
check whether the committed information rate (CIR) reaches the bandwidth that the user
applied for.
l
If the CIR is less than the bandwidth that the user applied for, the traffic profile bound
to the user is incorrect. Go to
.
l
If the CIR is equal to the bandwidth that the user applied for, go to
3.
Run the
undo service-port
command to delete the service port of the user. Then, run the
service-port
command to reconfigure a service port for the user and bind the user to the
proper traffic profile. Check whether the Internet access rate is restored.
l
If the Internet access rate is restored, go to
.
l
If the Internet access rate is not restored, go to
NOTE
When modifying the traffic profile, note the following:
l
The service ports bound to the traffic profile take effect at the same time when the traffic profile is
modified.
l
If the current traffic profile is bound to multiple service ports, run the
traffic table ip
command to
create the required traffic profile.
l
If the current traffic profile is bound to one service port, run the
traffic table ip modify
command to
modify the traffic profile.
Step 6
Check whether the user's MAC address has drifted from one ONU port to another.
1.
In global config mode, run the
display location
command to check multiple times
(recommended: three times) whether the user's MAC address has drifted away from the
port that originally learned it.
