EVPLAN Services
EVPLAN services of different users need to share the bandwidth. Hence, the VLAN/QinQ
scheme needs to be used for differentiating the data of different users. If the services of different
users need to be configured with different quality levels, you need to adopt the corresponding
QoS scheme.
As shown in
of user G need to be isolated from the services of user H. Hence, the IEEE 802.1q bridge needs
to be established on NE1 to achieve EVPLAN services.
IEEE 802.1q bridge: IEEE 802.1q bridge supports isolation by using one layer of VLAN tags.
This bridge checks the contents of the VLAN tags that are in the data frames and performs Layer
2 switching according to the destination MAC addresses and VLAN IDs.

to respectively access the VoIP server and the HSI server. In this case, the operator needs to
separately groom the VoIP services and HSI services, and isolate the data on the transmission
network side. On NE1, the IEEE 802.1ad bridge must be established to support the EVPLAN
services.
IEEE 802.1ad bridge: The IEEE 802.1ad bridge supports data frames with two layers of VLAN
tags. This bridge adopts the outer S-VLAN tags to isolate different VLANs and supports only
the mounted ports whose attributes are C-Aware or S-Aware. This bridge supports the following
switching modes:
