auto-voip oui-based priority
Use this command to configure the global OUI based auto VoIP priority. If the phone OUI is matches one
of the configured OUI, then the priority of trac from the phone is changed to OUI priority configured
through this command. The priority-value is the 802.1p priority used for trac that matches a value in
the known OUI list. If the interface detects an OUI match, the switch assigns the trac in that session to
the trac class mapped to this priority value. Trac classes with a higher value are generally used for
time-sensitive trac.
Default Highest available priority.

auto-voip protocol-based
Use this command to configure the global protocol-based auto VoIP remarking priority or trac-class. If
remark priority is configured, the voice data of the session is remarked with the priority configured
through this command. The remark-priority is the 802.1p priority used for protocol-based VoIP trac. If
the interface detects a call-control protocol, the device marks trac in that session with the specified
802.1p priority value to ensure voice trac always gets the highest priority throughout the network
path.
The tc value is the trac class used for protocol-based VoIP trac. If the interface detects a call-control
protocol, the device assigns the trac in that session to the configured CoS queue. Trac classes with a
higher value are generally used for time-sensitive trac. The CoS queue associated with the specified
trac class should be configured with the appropriate bandwidth allocation to allow priority treatment
for VoIP trac.
Note
You must enable tagging on auto VoIP enabled ports to remark the voice data upon egress.
