c) VLAN Table
The VLAN Table contains VLAN-specific settings for forwarding packets with VLAN tag. The
entries in the VLAN table are applied only to the packets received on ports whose
VTable Filter
Flag is set.
The VLAN table contains a maximum of 32 entries. Using the context menu (right mouse button),
entries can be deleted, added or the whole table can be deleted.
An entry in the VLAN table has the following meaning:
Valid:
This entry is used for packet forwarding. Entries that are not marked as valid, will be ignored.
When saving the configuration (Store) only valid entries are persisted.
VID:
The
VLAN ID
is the key in the VLAN table. Each VID may only exist once. The forwarding rules of
this entry are applied to packages with matching VIDs. The VID must be in the range of 0-4095.
FID:
The switch supports a maximum of 128 active of 4096 possible VLANs. The packet forwarding is
therefore internally based on the filter ID rather than the VLAN ID. For this purpose, each entry
must be assigned to a filter ID in the range 0-127. If 802.1Q is activated, the FID is also learned
during MAC address learning and stored in the Dynamic MAC table. The forwarding is then based
on the destination address and FID. In the static MAC table, the combination of MAC address and
FID can be specified manually.
OABR1/OABR2/100BTX/USB:
The individual port flags indicate to which ports packets with a specific VID should be forwarded.
Certain VLANs can be blocked if no port is activated.
