Link Status

Link Status displays the status of the Ethernet connections. Ethernet auto negotiation is often unreliable, especially between different vendors or old and new networking equipment. Failure of auto negotiation is generally not a cause for concern. However, if the negotiated rates change intermittently, or the link is down or there is no link, the link rate may need to be set manually on the Set Link Rate page. Intermittent data and voice outages may be caused by auto negotiation "flutter". Setting the link rate manually is recommended and ensures that the device at the far end of the connection will not renegotiate rates during VoIP operation.

Interface Information

The specific status and configuration information for the system interfaces is displayed in the Interface Information section. The MAC address of interface eth0 is needed to retrieve the VoIP ALG License Key if the license information is lost.

The interface statistics can point to areas of congestion in the network. If the errors statistic increase during normal operation of the device, it may be an indication of excessive congestion on the network interface. If the congestion is not corrected, the quality of voice calls will be affected. The topology of the network attached to the network interface with the errors should be examined and modified to better segment and isolate network traffic. See Link Status on page 3-6.
