M4300 Intelligent Edge Series Fully Managed Stackable Switches The two types of traffic are therefore segregated so that better service can be provided to the voice traffic. When a dot1p priority is associated with the voice VLAN port instead of VLAN ID, the priority information is passed onto the VoIP phone using the LLDP-MED mechanism. Thus, the voice data coming from the VoIP phone is tagged with VLAN 0 and with the exchanged priority. Regular data arriving on the switch is given the default priority of the port (default 0), and the voice traffic is received with higher priority, thus segregating both the traffic to provide better service to the voice traffic. The switch can be configured to override the data traffic CoS. This feature enables overriding the 802.1P priority of the data traffic packets arriving at the port enabled for voice VLAN. Thus, a rogue client that is also connected to the voice VLAN port does not deteriorate the voice traffic. When a VLAN ID is configured on the voice VLAN port, the VLAN ID information is passed onto the VoIP phone using the LLDP-MED mechanism. The voice data coming from the VoIP phone is tagged with the exchanged VLAN ID; thus, regular data arriving on the switch is given the default PVID of the port, and the voice traffic is received on a predefined VLAN. The two types of traffic are segregated so that better service can be provided to the voice traffic. Note: The IP phone must support LLDP-MED to accept the VLAN ID and CoS information from the switch. voice vlan (Global Config) Use this command to enable the Voice VLAN capability on the switch.
