5.8 VLAN (Bridge Mode Only)
The Virtual Local Area Network (VLAN) feature helps in logical grouping of network host on different physical LAN segments,
which can communicate with each other as if they are all on the same physical LAN segment.
With VLANs, you can conveniently, efficiently, and easily manage your network in the following ways:
·
Define groups
·
Limits the broadcast and multicast traffic to a specific VLAN group
– Improve network performance and reduce latency
·
Increase security
– Secure network restricts members to resources on their own VLAN
The SUs and End Point devices support QinQ VLAN feature that enables service providers to use a single VLAN ID to support
multiple customer VLANs by encapsulating the 802.1Q VLAN tag within another 802.1Q frame. The benefits with QinQ are,
·
Increases the VLAN space in a provider network or enterprise backbone
·
Reduce the number of VLANs that a provider needs to support within the provider network for the same number of
customers
·
Enables customers to plan their own VLAN IDs, without running into conflicts with service provider VLAN IDs
·
Provides a simple Layer 2 VPN solution for small-sized MANs (Metropolitan Area Networks) or intranets
·
Provides customer traffic isolation at Layer 2 within a service provider network
