Vlan Function - KTI Networks KS-115FM-V Installation Manual

2.4 VLAN Function

The switches support two VLAN modes. One is Port-based VLAN and
the other is 802.1Q VLAN.
The following configuration are supported:
1. VLAN Mode : Port-based mode or 802.1Q mode
2. VLAN mapping table setup : member ports setup for each group
3. Per port PVID setup : PVID setting, Tag mode setting
Port-based VLAN Mode
1. This mode supports 16 VLAN groups, Group 0 ~ Group 15.
2. Packet forwarding is performed only among the member ports in
same group.
3. Every packet, tagged or untagged, is forwarded from input port to
output port transparently without any packet modification.
4. Per port PVID setting is used for index to VLAN Group table. When
a packet is received, the associated PVID setting of the input port is
used to map to one VLAN group in VLAN group table. The mapping
index is retrieved from the least 4 bits (bit 3~0) of the PVID value.
5. Tag mode settings are preset with untagged mode for all ports and
not changeable in Port-based VLAN mode.
6. VLAN tag in every input tagged packet is ignored.
Note:
To provide more flexibility for LAN administrator in performing web man-
agement task, the internal MNG port which connects to the built-in Http
server is disclosed for PVID configuration. The MNG port is also config-
ured as the member port for all VLAN groups and untag port perma-
nently.
