Solution
CONFIGURATION STEPS:

STEP 1: Enable the G2 Interface as active. Please find the commands below for both command line and Web GUI.

CLI:

default# configure terminal
default(config)# interface FastEthernet 2
default(config-if-FastEth)# ip address 172.26.16.200 255.0.0.0
default(config-if-FastEth)# gw 172.26.16.1
default(config-if-FastEth)# type active
default(config-if-FastEth)# exit
default(config)# exit
default#copy running-config startup-onfig

GUI:

Open the Web Interface of the controller and follow the below instruction:
STEP 1: Configuration tab->Devices->System Setting->Ip Address->click Add->
Enter the ip address/netmask/gateway information and set as active.

STEP 2: Once after configuring the G2 interface as active, we need to reboot the controller for the changes to take effect.

STEP 3: In the active configuration, the second Ethernet interface must be configured with a static IP address (not DHCP) to a different L2 domain not as of the primary interface.

STEP 4: Take a different switch, configure vlan with the ip: 10.10.58.1 / 255.255.255.0.Create a vlan in the controller mapping to interface 2. Assign a non used ip in the vlan range and the default gateway should be the ip of the dsl home router. Let’s consider the vlan name as vlan 10.

Below is the switch configuration:

Interface GigabitEtherner 1/1
description "To MERU Controller"
Switchport trubk encapsulation dot1q
switchport mode trunk
switchport trunk allowed vlan 10
Interface vlan10
ip address 10.10.58.1 255.255.255
ip helper-address 10.10.58.50

STEP 5: Create an ESS profile from GUI below is the steps:

Open a Web GUI->security profile->Name the profile, with the security that is required->ok
Click on ESS->give a name for the ESS and SSID->map the vlan->click ok and save the configuration.

STEP 6: Connect a client to the SSID mapped for the guest vlan. It will get the ip address from the DSL modem and the clients will go online.

LIMITATIONS IF ANY: Please do not add the VLAN on the controller for the G2
