NetVanta 3430 Throughput speed

[mrchrisosburn]

We have a 30 mb internet connection and when doing a speed test through t he router i only get ~10 mb. If i bypass the router I get the full 30.

I looked at the Troubleshooting Internet Test Speed Issues and still getting the same results.

Im really not sure what to do from here and any advice would be greatly appreciated.

Attached is the scrubbed running config and interface information.

Thanks

Thank you for asking this question in the Support Community, and for sending portions of the configuration.  When you get a chance, at the time of this post, I recommend you upgrade the firmware to R10.5.3.  I also recommend you set the traffic-shape rate <value> command on the Internet interface to the amount of upload speed you have, and verify that the MTU has not been changed from the default (which it appears to be default in the configuration you sent, which is good).

When you are running the Internet speed test, is the PC connected directly to the Ethernet 0/2 port of the ADTRAN (as you have indicated this to be the LAN port in the configuration)?  Have you tried multiple PCs and multiple Internet speed testing web sites?

Hi Levi

I will set the traffic-shape rate on that interface as you suggested.

When i ran the bandwidth tests, i ran them from two different services; bandwidthplace.com, and speedtest.net. All 4 tests(two bypassing, and two through the router) were made with the same computer.

This might seem like a silly question but from your interface statistics posted in your config file the eth 0/1 interface is showing errors.  Are these errors accruing?  What type of service are you connecting the Adtran to? 

eth 0/1 is UP, line protocol is UP

    5509 input errors, 0 runts, 0 giants

    5509 no buffer, 0 overruns, 0 internal receive errors

    0 alignment errors, 0 crc errors

No buffer errors occur when a packet is discarded because there was no buffer space. Broadcast storms on Ethernet networks and bursts of noise on serial lines are often responsible for no input buffer events.   A lot of no buffer errors also show up on eth 0/2, but not nearly the same amount of input errors. A firmware upgrade should definitely be done; these errors could be the result of something else like a memory leak or something wrong in the code (not saying they are, just that it is motivation to get on a newer release of code).

The interface is showing the same number of no buffer errors as in the configuration file so they are not accruing.

The service provided to the Adtran is Ethernet.

Thanks for your reply!

- I have a couple of questions regarding your setup and what you have tried. First, I'm not sure if any changes have been made to the configuration since your original post. If so, could you post an updated version to this thread for us to look over. Please remember to remove any sensitive information.

- Did you get a chance to try the bandwidth tests with the traffic-shape rate set as was suggested in a previous post?

- When you tested through the router, was your PC ever plugged directly into eth 0/2 (LAN)?

- Did you try the speed test with another PC? If so what were the results?

- What firmware are you running on the NetVanta? From the configuration file it looks like 18.01.01. It may be worth going ahead and upgrading to R10.5.3.

Let us know if you have any questions.

Thanks,

Noor

Hi

Thanks for the follow up. I had opened a ticket with the ISP and they adjusted something on their FlashWave or Switch which seems to have resolved the issue.

Thanks for the follow up and thanks to the members of the community who assisted me with troubleshooting.
