802.1p support on Network Interface Card (NIC)

This article described how to enable 802.1p tagging support on Ethernet Network Interface Card (NIC) adapter.

When 802.1p support is disabled on a computer, where MiaRec is running, then following issue may occur:

  • one-way audio (when only one side of conversation is recorded)
  • no audio is recorded at all (both sides of conversation are not recorded).

802.1p is is a standard that enables Quality of Service (QoS). QoS gives higher priority to voip audio packets, thus improving a call quality (less delays, less packet loss).

When one of above issues occurs, it is necessary to check if NIC supports 802.1p.

Open properties of your NIC.

And then click on "Configure" button.

Network Interface Card Properties

Check if you have there option "802.1p Support" and make sure it is "Enabled".

Note, if you do not have such option, then do nothing (your NIC supports 802.1p by default).
