After configuring Audiocodes’ VM based SBC in a single NIC state, a need come up where a WAN interface needed to be brought online. When attempting to set an IP to the interface group the following error was displayed:
nwDevTable_CrossValidateRow: Validation failed, the ethernet group (index 1) already contains the OSN interface. No other device can be configured on this group. MATRIX DeviceTable: Unable to Activate Line(1) since it is invalid
As we can see, the Ethernet Device Status shows InternalIF OSN is the only other available device.
IP Interface Status doesn’t show much help either:
An idea attempted was exporting the configuration ini file, adding the configuration entries for the second NIC, applying the changed configuration file and restarting appears to bring it up, but it still had a red state of down/unknown. (the WAN_DEV Ethernet Device was created in the config file)
The following steps were taken to get the Audiocodes VM to work:
- Delete the logical Virtual Machine network interface
- Restart the VM
- Add a new NIC to the VM
- Restart the VM
Once those steps were taken, the interface came up, and the IP was active!
