Tag-based:
A tag-based VLAN identifies its member by VLAN-ID. If there are any
more rules in ingress or egress filtering lists, this rules determines if
the packet will be forwarded or not. The switch supports standard of
802.1q.
Each tag-based VLAN you set up must get a VLAN name and VLAN
ID. A valid VLAN ID is 1 up to 4094. You can create up to 24 Tag VLAN
groups.
As soon as the VLAN mode is set on "tag-based", the setting double-
tag mode will be offered. If the double-tag mode is activated all
packets (tagged or untagged) will get a VLAN tag. Packets which have
already an "inner" tag will get in addition an "outer" tag. Internet ser-
vice provider use this function for additionally tagging in their own
network of customers VLAN tagged data streams.
If the double-tag mode is activated, you can select the ports on which
the doubled VLAN tags should be used.
