Remarks
N/A

By default, a port modifies the
CoS and DSCP values for
voice VLAN packets to 6 and
46, respectively.
If a port trusts the QoS priority
settings in incoming voice
VLAN packets, the port does
not modify their CoS and
DSCP values.
If you execute the voice-vlan
qos and voice-vlan qos trust
commands multiple times, the
most recent configuration
takes effect.
