802.1P Tag Priority Mode - Planet VC-810S User Manual

4.5.1 802.1p Tag Priority Mode

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 VDSL2 Switch recognizes 802.1Q VLAN tag packets and
extracts the VLAN tagged packets with User Priority value.
