11 Layer 2 Protocol Transparent
Transmission Configuration
About This Chapter
This chapter describes the concept, configuration procedure, and configuration examples of
Layer 2 protocol transparent transmission.
11.1 Overview of Layer 2 Protocol Transparent Transmission
This section describes the concept of Layer 2 protocol transparent transmission.
11.2 Layer 2 Protocol Transparent Transmission Features Supported by the S7700
This section describes the Layer 2 protocol transparent transmission features supported by the
S7700.
11.3 Configuring Interface-based Layer 2 Protocol Transparent Transmission
When each interface of a device on the backbone network is connected to only one user network
and Layer 2 protocol packets sent from the user network do not need VLAN tags, you can
configure interface-based Layer 2 protocol transparent transmission so that Layer 2 protocol
packets can be transparently transmitted on the backbone network.
11.4 Configuring VLAN-based Layer 2 Protocol Transparent Transmission
When each interface of devices on the backbone network is connected to multiple user networks
and Layer 2 protocol packets sent from user network contain VLAN tags, you can configure
VLAN-based Layer 2 protocol transparent transmission so that Layer 2 protocol packets are
transparently transmitted on the backbone network.
11.5 Configuring QinQ-based Layer 2 Protocol Transparent Transmission
When each interface of devices on the backbone network is connected to multiple user networks
and Layer 2 protocol packets sent from user network contain VLAN tags, you can configure
QinQ-based Layer 2 protocol transparent transmission so that Layer 2 protocol packets can be
transparently transmitted on the backbone network and that VLAN IDs of the carrier can be
saved.
11.6 Maintaining Layer 2 Protocol Transparent Transmission
This section describes how to debug Layer 2 protocol transparent transmission.
