Step 4
Click on the subscriber unit in question and look at the throughput column for your
downlink service flow.
If you are running 1Mbps of iperf traffic, you should expect to see approximately 1000kbps.
If not, the problem (99% of the time) is classification-related.
If you are certain that the problem is not related to provisioning, then you will need to verify
that the packets are being received properly by the AN100U/UX.
Step 5
The best way to do this is to connect a hub directly to the AN100U/UX's data-port, and
capture the traffic being received at that point using Ethereal (http://www.ethereal.com/).
Step 6
If you see traffic across your service flow, then the test traffic is being received by the
AN100U/UX, classified, scheduled, and sent to the SU. The problem must be downstream.
Step 7
Login to the CLI as outlined in “Connecting to the Subscriber Unit Command Line
Interface” on page 2-6 and enter the following command:
show interfaces
Step 8
Observe the DlByteCount statistic (4th column, 7th row).
Step 9
If you see the downlink byte counter incrementing by about 1000kbps, this implies that the
traffic is being received properly by the SU. The problem must then be further downstream.
Step 10 Log into your subscriber unit using the super/super credentials and enter the following
commands:
shell
brgStat
Step 11 Wait 15 seconds then type "brgStat" again. Observe the difference between the first and
second values of the Wireless Unicast Pkt to Ethernet counter. Is this counter
incrementing as expected? If not, then the problem may be related to one of the filters
implemented in the subscriber unit in order to avoid VLAN leakage when CPE-to-CPE
communication is enabled in the sector. At this point, you should call Redline technical
support for further assistance.
Step 12 If you do see the packet counters incrementing, then the problem must be downstream of
the RedMAX system.
Tracing Uplink Connectivity Issues
Step 1
Ensure that your test traffic (i.e. iperf) is running.
Step 2
Navigate to your Monitoring > SS Info.
Step 3
Click on the subscriber unit in question and look at the throughput column for your
downlink service flow.
If you are running 1Mbps of iperf traffic, you should expect to see approximately 1000kbps.
If not, the problem (99% of the time) is classification-related.
