The ports on which you configure protocol-based Auto VoIP are made members of the voice
VLAN automatically. By default, no VLAN is used for the voice VLAN. You must create a
voice VLAN first.

OUI-Based Auto VoIP
OUI-based Auto VoIP prioritizes VoIP packets based on the bytes of the organizationally
unique identifiers (OUIs) in the source MAC address. The switch is preconfigured with a
default list of OUIs. You can also add OUIs that need prioritization. The switch can support up
to 128 OUIs, including the default OUIs.

default list of OUIs. You can also add OUIs that need prioritization. The switch can support up
to 128 OUIs, including the default OUIs.
By default, the switch uses the highest available priority for all frames that match OUIs on the
OUI list. You can override the default priority and configure a different priority. You need to
map the priority to a traffic class to achieve the desired egress queuing for VoIP traffic.

The switch assigns all VoIP traffic that matches a known OUI list to the VoIP VLAN. If you
modify the VoIP VLAN, all existing MAC VLAN entries are removed. The MAC entries are
deleted from the forwarding database and relearned with the new VLAN as the devices
transmit packets. The port VLAN membership also changes.

The switch assigns untagged VoIP traffic only to the VoIP VLAN and uses the associated

If you enable port mirroring on a port that is configured for Auto VoIP, the port remains
