Checking for speed and duplex errors
If you selected auto-negotiation (auto) for your in-path and primary interfaces, you must ensure that the Edge appliance negotiated the speed and duplex at the rate your devices expect. For example, ensure settings are auto on the LAN and WAN and 100 FULL on the LAN and WAN. You can verify your speed and duplex settings in the Configure > Networking: Inpath0_0 page and the Networking > Networking: Base Interfaces page of the Management Console.
1. In the Management Console, choose Administration > Diagnostics: System Logs.
2. Check the system logs for duplex or speed errors.
3. Choose Networking > Reports: Current Connections page.
4. Check for duplex and speed errors.
If you find errors, change the speed and duplex settings on your LAN and WAN interface in the Configure > Networking: Inpath 0_0 page.
