M4300 Series and M4300-96X Fully Managed Switches
VLANs
Software Administration Manual
45
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. This segregates 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.
The table below describes how does PVID and tagging are handled by voice VLAN in the
four modes.

VLAN (4088) automatically
No priority is assigned by voice VLAN
automatically. If the user want higher priority
for voice traffic, user needs to manually
configure it. This priority (dot1p) is conveyed
from the Voice device as part of VLAN tag in
the VoIP traffic. The user is not expected to
configure any CoS on the port.

The user needs to configure dot1p priority

No need to set PVID for voice but may

be communicated to the VoIP device.
Note:
For Voice VLAN feature, CoS override can be enabled for 8 ports only.
