25.1.5 Stacking VLAN Translation and Aggregation Mode

• Compared to VLAN translation and aggregation mode, this mode adds an outer tag.
• This mode performs VLAN translation between the NNI and UNI sides.
• The NNI side is tagged with double tags, S(SVID) + C(CVID), and the UNI side is tagged with a C
tag.
• Two or more different UNI VLAN IDs translated to a NNI VLAN ID is VLAN aggregation.
• 1:1 VLAN translation mapping is VLAN translation.
• The IES only forwards traffic for VLANs configured on the UNI side.
• Stacking VLAN translation and aggregation can co-exist with other VLAN modes except
transparent VLAN.

25.1.6 VLAN TLS Mode

• VLAN Transparent LAN Service (TLS) adds an outer tag regardless of whether the UNI side is
untagged or single tagged.
• VLAN TLS packets are not handled by any control protocol (DHCP, IGMP, ...), so the UNI traffic is
tunneled into the TLS VLAN.
• VLAN TLS mode forwards all traffic of VLANs not configured as part of other modes.
• VLAN TLS can co-exist with other VLAN modes except transparent VLAN.
