Huawei quidway s7700 - Checking the Configuration; Configuring VLAN Transparent Transport; Establishing the Configuration Task

3.9.4 Checking the Configuration
After an mVLAN is configured, you can check information about the mVLAN.
Prerequisite
The configurations of an mVLAN are complete.
Procedure
l Run the display vlan command to check information about the mVLAN. The command
output shows information about the mVLAN in the line started with an asterisk sign (*).

3.10 Configuring VLAN Transparent Transport
VLAN transparent transport improves forwarding efficiency. A switch directly forwards packets
of a specific VLAN without sending the packets to its CPU.
3.10.1 Establishing the Configuration Task
A VLAN enabled with transparent transport cannot be configured as a multicast or control
VLAN.
Applicable Environment
A company has multiple subsidiary companies. When the parent company attempts to
communicate with a subsidiary company, data is processed by a core switch before being sent
to the parent company or subsidiary company. If multiple subsidiary companies communicate
with the parent company at the same time, processing capabilities of the core switch deteriorate.
The communication efficiency is adversely affected and communication expenditure increases.
VLAN transparent transport can be configured on the core switch to prevent this problem.
On the network shown in Figure 3-9, switch B is enabled with VLAN transparent transmission.
After that, switch B directly forwards data from the specified VLAN instead of sending the data
to its CPU. This improves processing capabilities of the switch, reduces communication
expenditure, and minimizes the probability of malicious attacks on the switch.
