Overview
When running an Exinda appliance on a virtual machine, you may encounter issues where no traffic is visible. This can be due to incorrect network interface configurations, SPAN/mirror port settings, or other VM-level settings. This article provides a step-by-step guide to troubleshoot and resolve such issues, particularly focusing on configurations within virtual environments like Proxmox.
Information
To resolve traffic visibility issues on an Exinda appliance running on a virtual machine, follow these steps:
-
Verify VM Network Interface Configuration:
- Ensure you are using the recommended network adapter type.
- Confirm that the correct number of network interfaces are configured.
-
Enable Promiscuous Mode:
- Enable promiscuous mode on the virtual interfaces of your Exinda VM to allow it to see all traffic.
-
Check SPAN/Mirror Port Configuration:
- Review SPAN or mirror port settings on the physical switch.
- Verify that mirrored traffic is sent to the correct virtual port where Exinda is listening.
-
Verify NIC Speed Settings:
- Check NIC settings in your virtualization platform.
- Ensure they match the settings on your physical network infrastructure.
-
Check Exinda Configuration:
- Go to "Configuration > System > NICs" and verify all expected interfaces are present and correctly configured.
- Navigate to "Monitor > Interfaces" to check if any traffic is showing in the last 5 minutes.
-
Review Internal Traffic Settings:
- Go to "Configuration > System > Setup > Monitoring".
- Temporarily uncheck the "Ignore Internal-Internal" checkbox and click "Apply Changes".
-
Restart Monitoring Processes:
- Access the Exinda CLI and use the command:
en conf t service collector restart.
- Access the Exinda CLI and use the command:
-
Check for Non-Existent Interfaces:
- Review the running configuration for any ghost configurations of non-existent interfaces.
- Remove any such configurations using the CLI if found.
If the issue persists, additional configuration file changes may be required on the Proxmox interface bridge.
