Configuring 802.1Q VLAN
This section uses RHEL 7.5 as an example.
To configure 802.1Q VLAN in the operating system:
1. Execute the
modprobe 8021q
command to load the 802.1Q module.
2. Execute the
ip link add link ethX name ethX . id type vlan id id
command
to create a VLAN interface on a physical port. The
ethX
argument represents the physical port
name. The
id
argument represents the VLAN ID.
3. Execute the
ip
–
d link show ethX . id
command to verify that the VLAN interface has been
created successfully.

4. Execute the
ip addr add ipaddr / mask brd brdaddr dev ethX . id
and
ip link
set dev ethX . id up commands to assign an IP address to the VLAN interface and set the
VLAN interface state to UP , respectively. The
ipaddr / mask
argument represents the IP
address and mask of the VLAN interface. The brdaddr argument represents the broadcast
address. The
ethX . id
argument represents the VLAN ID.
To delete a VLAN interface, execute the
ip link set dev ethX . id down
and
ip link
delete ethX . id
commands.

Configuring IEEE 802.1ad Provider Bridges (QinQ)
1. Install the official lediag tool.
a. Copy the lediag tool package into the operating system.
b. Execute the
tar –zxvf file_name.tar.gz
command to decompress the package.
c. Execute the cd <lediag_directory> command to navigate to the directory where the
decompressed package resides and then use the make command to compile the file.
2. Start the tool and switch to the corresponding network adapter.
a. After compiling, execute the
./load.sh –b10eng
command in the lediag folder to enter
engineering mode.
b. If the server has multiple network adapters installed, use the dev <num> command to
switch to the corresponding network adapter. The <num> argument represents the number
