1. Only one HUB(8)-U( ) ETU can be assigned and installed for each cabinet.
2. A virtual (logical) LAN is a local area network with a definition that maps workstations on a basis other than
geographic location (for example: department, user type, or primary application). The virtual LAN controller can
change or add workstations and manage load balancing and bandwidth allocation easier than with a physical
picture of the LAN. Network management software keeps track of relating the virtual picture of the LAN with the
actual physical picture.
3. When VLAN Mode is enabled, the port based Tag VLAN feature can be used. In Tag VLAN mode, a received
packet is switched according to a combination of the Address and VLAN ID. When the incoming packet is not
tagged or VLAN ID = 0, the VLAN ID is set to the default assigned by Memory Block 1-16-05 (Default VLAN ID
Assignment). Default LAN ID range is 0001~4095 (0x001~0xfff Hex).
4. For Tag VLAN feature, the HUB(8)-U( ) ETU has a VLAN table and an entry in the table is Media Access Control
(MAC) address and VLAN ID source dependent. Therefore, multiple entries could have the same address with
different VLAN IDs.
5. VLAN table ports 1~4 are members of VLAN1, and the tag is removed before forwarding to all ports.
VLAN table ports 1 and 5~8 are members of VLAN2, and the tag is added to the untagged packet (or tagged
packet remains) before being forwarded to ports 5~8.
