• The uplink port joins the NNI VLAN specified in VLAN modes, multicast VLAN, the management
VLAN, and the VoIP VLAN.
25.1.1 Transparent VLAN Mode
• Transparent VLAN does not change the type of the VLAN tag in uplink and DSL ports.
• In the uplink port, the VLAN Tag Protocol Identifier (TPID) is a Service provider Tag Protocol
Identifier (S TPID). You can configure the S-tag TPID to be the same as the Customer TPID (C
TPID) (0x8100), and the users will think it is fully transparent.
• You cannot use other VLAN modes on a port using transparent VLAN.
Note: Use the
interface ge-nni <
portlist
>
and
vlan all
commands to add Gigabit
Ethernet uplink ports to all VLANs (1 ~ 4093) to make sure VLAN transparent
traffic can go through the uplink.
25.1.2 VLAN Tagging and Trunk Mode
• An S tag with PVID is added in the NNI side for untagged packets from the UNI side.
• The VLAN ID for single-tagged packets is not changed on either side, but the Tag Protocol
Identifier (TPID) is different. The Service provider Tag Protocol Identifier (S TPID) is on the NNI
side and a Customer TPID (C TPID) is on the UNI side.
• The IES only forwards traffic for VLANs configured on the UNI side. If you configure the UNI side
as untagged only, the IES only forwards untagged packets.
• VLAN tagging and trunk can co-exist with other VLAN modes except transparent VLAN.
25.1.3 Stacking VLAN Tagging and Trunk Mode
• Compared to VLAN tagging and trunk mode this mode adds an outer tag.
