8.5.2 Q-in-Q configuration example
Objective:
Configure the termination of subnet 192.168.1.1/24 combination C-VLAN: 741, S-VLAN: 828 on the physical
interface gigabitethernet 1/0/1.
Solution:
Create sub-interface for S-VLAN: 828
esr(config)# interface gigabitethernet 1/0/1.828
esr(config-subif)# exit
Create a Q-in-Q interface for the S-VLAN: 741 and configure the IP address from the required subnet.
esr(config)# interface gigabitethernet 1/0/1.828.741
esr(config-qinq-if)# ip address 192.168.1.1/24
esr(config-qinq-if)# exit

3 Create parameter profile for USB
modem and switch to the profile
configuration mode.
esr(config)# cellular profile <ID> <ID> – identifier of USB modem
parameter profile, set in the
range of [1..10].
4 Specify parameter profile description
(optional).
esr(config-cellular-profile)#
description <DESCRIPTION>
<DESCRIPTION> – profile
description, set by the string of
up to 255 characters.
Besides assigning IP address, it is necessary to disable firewall or to configure corresponding
security zone on Q-in-Q interface.
