Table 5-3. VLAN Port Configuration Fields
Field Description
Interface Select the port on which to configure the VLAN settings.
Port VLAN ID The VLAN ID that this port will assign to untagged or priority-tagged frames received on this
port. This value is also known as the Port VLAN ID (PVID). The PVID is set to the ID of the
VLAN of which the port is an untagged member. The PVID is not configurable.
In a tagged frame, the VLAN is identified by the VLAN ID in the tag.
By default, the PVID is 1 for all ports, which is the VLAN ID of the default VLAN, VLAN 1.
Port Priority The default 802.1p priority assigned to Layer-2 untagged packets arriving at the port. A value
of 0 (the default) indicates the lowest priority, commonly used for routine traffic, and 7 indicates
the highest priority, often reserved for application such as voice and video. The eight port
priorities are internally mapped to four class-of-service (CoS) queues. The queues provide
differentiated handling when forwarding traffic within the switch (assuming there is congestion
on the switch that requires prioritizing traffic).
The port priority value is not assigned to tagged packets, which carry priority information in
the VLAN tag, or to IP packets that carry priority information in the Differentiated Services
Code Point (DSCP) field.
A priority value is forwarded externally only if the port is configured as a tagged port.
To modify these settings for one or more interfaces, select the interface and click Edit. Or, click Edit All to
configure all interfaces at the same time.
