3.2.17 VLAN Configuration
S-Port default is 0x88A8, but may be user defined
A virtual LAN (VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer (OSI layer 2). This
device supports C-Port (802.1Q, with EtherType 0x8100) and S-Port (802.1ad or QinQ, with EtherType 0x88A8 or user defined) configurations,
with both ingress and egress filtering and allowed VLAN lists, with up to 16 individual VLAN ID groups.
Port VLAN: For Fiber and/or LAN port, sets the VID for the port. VID 1 is the "default VID". A VID from 2~4095 will set the 'access' VID for
that port.
Port Type: The C-Port type is a standard 802.1Q, single, inner tag where the "C" refers to 'customer' in MEF (Metro Ethernet Forum)
terminology. The S-Port type, where "S" refers to 'service provider', is the outer tag for 802.1ad or QinQ, which is added to an Ethernet frame
which already has a 802.1Q tag.
Ingress Acceptance: This is an acceptance filter that is applied to packets coming into the Fiber or LAN port. Three settings are supported
here, all packets tagged and untagged, only tagged packets or only untagged packets. Packets that do not match the acceptance filter are
dropped.
Egress Tagging: How packets leave the Fiber or LAN port are affected by this setting:
Untag the port VID. All packets which match the port VLAN VID will be untagged on egress
Tag All. All packets with tags will keep their tag and any untagged packets will be tagged with the Port VLAN VID.
Untag All. Tags are removed from all packets which egress this port.
Allowed VLANS: In this field, all VIDs which will be allowed can be specifically addressed here. Individual VIDs entered are separated by
commas, while ranges of VIDs are separated by dashes. (ex. 1, 10-24). Up to 16 VIDs are supported.
