Assigning VLANs to Interfaces

The interfaces of the EDS500 devices can transmit Ethernet frames either without 802.1Q
VLAN tag (untagged, Access-Port) or with VLAN tag (tagged, Trunk-Port). For this you can
select a VLAN id from the range between (including) 1 and 4094.
Access ports are used mainly to connect terminal devices. On an access port incoming
Ethernet frames get a VLAN tag, frames that leave the port in the direction of the terminal
device get stripped off the VLAN tag and the data is transmitted untagged. Each access port
is associated with exactly one VLAN id.
Those interfaces that connect the network infrastructure are configured as trunk ports.
Ethernet frames are transmitted with 802.1Q VLAN tag (tagged). You must differentiate
between secure trunk ports and trunk all ports. While trunk all ports accept and transmit any
VLAN id (and are therefore not associated with specific VLAN ids), the secure trunk ports have
