Tagged indicates that the device is using the IEEE 802.1Q tagged frame format, and that both the
VLAN ID and the Layer 2 priority values are being used, as well as the DSCP value. The tagged
format includes an additional field, known as the tag header. The tagged frame format also
includes p riority t agged f rames a s d efined b y I EEE 8 02.1Q-­‐2003.

L2 Priority is the Layer 2 priority to be used for the specified application type. L2 Priority may
specify one of eight priority levels (0 through 7), as defined by IEEE 802.1D-­‐2004. A value of 0
represents u se o f t he d efault p riority a s d efined i n I EEE 8 02.1D-­‐2004.
