Overview
This article provides information regarding the NIC (Network Interface Card) settings page, which is used to set the following:
- Speed, duplex, and MTU of the system NICs.
- The behavior of the bridges in the event of an appliance failure (for example, fail to wire).
- The behavior of the second port in a bridge pair when the first port goes down (for example, enabling link-state mirroring).
Information
The Exinda appliance and devices that are connected to the appliance must have the same speed and duplex settings for their network interfaces. In most cases, the default settings will work as the Exinda is setup to auto-negotiate. However, some equipment is not compatible with this setting.
If the appliance and connected devices are using different speeds and duplex settings, the devices may not communicate, and traffic may be dropped. In this case, you may notice collisions, errors, packet loss, and network delays on the Exinda NICs, which will cause the System health status to show as Warning and the offending interface(s) will be highlighted.
To resolve this, check if the router or switch is hard-coded to a speed or duplex setting. If hard-coded, then either set all devices to auto-negotiate or set the Exinda device to the same speed and duplex mode.
Note
For further troubleshooting, click on the system warning or view the NIC Diagnostics by clicking the View NIC Diagnostics link.
