Zyxel IES4005 [181/236] Vlan translation and aggregation mode
Chapter 25 VLAN
IES4005M User’s Guide
181
An S tag with SVID and a C tag with PVID are added on the NNI side for untagged packets from
the UNI side.
The C tag for UNI side, single-tagged case is not changed in both sides, and a S tag with SVID is
added.
The IES only forwards traffic for VLANs configured on the UNI side.
VLAN stacking tagging and trunk can co-exist with other VLAN modes except transparent VLAN.
25.1.4 VLAN Translation and Aggregation Mode
VLAN translation changes the VLAN tag on traffic received from a DSL port to another VLAN ID for
the service provider’s network. This makes it easier to deploy customer-specific VLANs because all
the CPE devices can use the same VLAN configuration. You only need to configure VLAN translation
on the IES to use unique VLAN IDs for each CPE device’s traffic.
This mode performs VLAN translation between the NNI and UNI sides.
The NNI side is tagged with an S tag and 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.
Only VLANs joined on the UNI side will be forwarded.
VLAN translation and aggregation can co-exist with other VLAN modes except transparent VLAN.
