4.8.3 802.1p-based Priority
QoS settings allow customization of packet priority in order to facilitate delivery of data traffic that might be affected by latency
problems. When 802.1p Tag Priority is applied, the PoE Switch recognizes 802.1Q VLAN tag packets and extracts the VLAN
tagged packets with User Priority value.
