packets and the VID for tagged packets, tag-aware and tag-unaware network
devices can coexist on the same network.
A switch port can have only one PVID, but can have as many VID as the switch
has memory in its VLAN table to store them.
Because some devices on a network may be tag-unaware, a decision must be
made at each port on a tag-aware device before packets are transmitted –
should the packet to be transmitted have a tag or not? If the transmitting port is
connected to a tag-unaware device, the packet should be untagged. If the
transmitting port is connected to a tag-aware device, the packet should be
tagged.
Default VLANs
The MC355-1T/1S initially configures one VLAN, VID = 1, called "default." The
factory default setting assigns all ports on the MC355-1T/1S to the "default". As
new VLAN are configured in Port-based mode, their respective member ports are
removed from the "default."
VLAN Group
This function allows disable or enable the IEEE 802.1Q VLAN operation mode.
Press the “Apply” button to save the latest configuration of the MC355-1T/1S.
