Port Negotiation Problems

If traffic is not passing, or you are getting low speed throughput, please check status port for errors and sysinfo 4 for port settings.

If the router or switch you are connecting the radio to is in auto/auto, please disable auto neg on the Apex or IDU and then re-enable it to reset the port and make sure it shows status is on. Check with status port and sysinfo 4. If you want to hard code both sides to 100/full, that is fine as well, but please ensure you have disabled auto negotiate prior to hard coding the interface. It is also possible to hard code to 1000/full, but some equipment will not work when hard coded to 1000 Mbps and must auto-negotiate there.

Auto-Negotiation typically works perfectly fine. When problems are observed with auto negotiate enabled, it may be a cable issue or damaged port that is preventing the two devices from linking at the best possible rate. This is typically confirmed by manually setting them to the desired speed and observing that they will not link.
