Solution
The LanSchool application will work with Meru only when the multicast flag is enabled along with the UDP port added under the UDP broadcast upstream/downstream. 

CONFIGURATION STEPS:

GUI Steps:

STEP 1: Go to the "Configuration" tab in the web GUI >> Click on "System settings" under "Devices" >> Go to the "UDP Broadcast Up" tab >> Click on Add and add the ports 796 and 1053. Then go to the "UDP broadcast Down" tab and add the ports 796 and 1053.

STEP 2: Go to the specific ESS profile that will be used by the clients using the Application. Go to "ESS" option under "Wireless" select the respective ESS profile and Set "Allow Multicast Flag" to ON.

Note: Multicast is allowed only when the ESS has a one-to-one mapping with the default VLAN for this ESS. No other ESS can use the same VLAN.

STEP 3: The "Data transmission" in LanSchool Teacher application has to be set to "IP-Multicast".

CLI Steps:

meru# configure terminal
meru(config)# ip udp-broadcast upstream 796
meru(config)# ip udp-broadcast downstream 796
meru(config)# ip udp-broadcast upstream 1053
meru(config)# ip udp-broadcast downstream 1053
meru(config)# exit
meru#

Enabling Multicast on the specific ESS profile:

meru# configure terminal
meru(config)# essid <ESS Profile Name>
meru(config-essid)# multicast-enable
meru(config-essid)# exit
meru(config)# exit
meru#
