Overview
Use this command to configure the Layer 2 user priority advertised when the
transmission of LLDP-MED Network Policy TLVs for voice devices is enabled. This is
the priority in the User Priority field of the IEEE 802.1Q VLAN tag, also known as the
Class of Service (CoS), or 802.1p priority. When LLDP-MED capable IP phones
receive this network policy information, they transmit voice data with the specified
priority.
