AutoVoIP detects the VoIP streams and put the VoIP streams in the specific VLAN (auto-voip 

VLAN) and provides higher Class of Service to the VoIP streams automatically (both data 
and signaling). It detects the VoIP streams in two modes.

Protocol-based Auto VoIP. In a VoIP system, various signaling protocols are used to 
establish the connection between two VoIP devices. The supported signaling protocols 
are SIP, H.323, and SCCP.

OUI-based Auto VoIP. The OUI-based Auto VoIP feature prioritizes VoIP packets based 
on the OUI bytes in the source MAC address. A default list of OUIs is maintained. User is 
also allowed to configure OUIs that need prioritization apart from the default OUI list. Up 
to 128 OUIs are allowed on the device or system, including the default OUIs.

If voice VLAN and Auto-VoIP are enabled at the same time, one of 
them is operational. If the connected phone is LLDP-MED capable, 
voice VLAN has precedence over the Auto VoIP and Auto VoIP is 
operational if the phone does not support LLDP-MED.

This command is used to configure auto VoIP mode. The supported modes are 
protocol-based and OUI-based. Protocol-based auto VoIP prioritizes the voice data based on 
the layer 4 port used for the voice session. OUI-based auto VOIP prioritizes the phone traffic 
based on the known OUI of the phone.
