6. If port-based or tag-based VLANs are configured on the switch, type
the name or VID of the VLAN to use the filter.

4.4.7 VLAN configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast
domain. It allows you to isolate network traffic so only members of the same
VLAN receive traffic from other VLAN members. Creating a VLAN from a
switch is logically equivalent to reconnecting a group of network devices to
another Layer 2 switch. However, all the network devices are still plugged
into the same switch physically. The switch supports port-based and
protocol-based VLANs. In the default configuration, VLAN support is
enabled and all ports on the switch belong to the default VLAN, whose
VLAN ID (VID) is 1.
Note: The default VLAN cannot be deleted.
Port-based VLANs (IEEE 802.1Q VLAN)
This feature is an IEEE 802.1Q specification standard. Therefore, it is
possible to create a VLAN across devices from different switch vendors.
IEEE 802.1Q VLAN uses a technique to insert a “tag” into the Ethernet
frames. The tag contains a VLAN Identifier (VID) that indicates the VLAN
numbers.
