same VLAN members. Basically, creating a VLAN from a switch is logically equivalent of
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 1008 switch supports both port-based and protocol-based VLANs from the web.
By default, VLAN support is enabled and all ports on the switch belong to the default
VLAN. The default VID is 1.
NOTE: The default VLAN can't be deleted or modified.
Port-based VLANs (IEEE 802.1Q VLAN)
The port-based tagging rule 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.
Protocol-based VLAN
In order for an end station to send packets to different VLANs, it has to be either
capable of tagging packets with VLAN tags or attached to a VLAN-aware device that
is capable of classifying and tagging the packet with different VLAN IDs.
