Purpose
This test is intended to validate device-level support for Supernetting features of the Celona platform.
Test infrastructure
Celona network w/ (1) AP
UE under test
CPE connected to a laptop or pi
Set the config on CPE GUI
Login to CPE GUI ->Lan->ethernet->DHCP Mode->relay
go to CPE GUI->Lan->Dhcp/Addressing->IP Passthrough->Disabled
Test characteristics
This test involves the following parameters and/ or variables (in addition to those described in the General Test Details and Characteristics -
Recorded Data
In addition to the information described in the General Test Details and Characteristics section and the test characteristics described, the following information is recorded:
Validation of IP address on supernetting device
Running UL/DL iperf traffic to validate the data traffic through supernet device
Procedure
CPE Connected to RAN
From Ethernet cable of CPE connect to a laptop or pi
For debugging connect CPE USB connection to laptop or pi
Enable wifi on the laptop or pi and connect from Celona Guest wifi ip connect to laptop or pi
Bring up dhcp server on pi specifically isc-dhcp-server. Configuration file is at: /etc/dhcp/dhcpd.conf
As per CPE settings mentioned in Set the config on CPE GUI configure for the CPE
On the Edge page of CSO, need to add an Advance Network Config, this config will have the subnet like mentioned in the screenshot by name <>, this subnet is what the devices behind CPE are part of.
Once advance network config is done, we need to map this advance network config to the respective device group from device group page.
Add route on the pi box (dhcp server) via udpf vlan domain interface .(example:sudo ip route add 172.18.0.0/24 via 197.197.197.89 dev eth0.797).without this route supernet device behind CPE will not get 172.18.x.x address
On windows any desk client machine toggle Ethernet network adapter on Control panel Network connections
