7. Remove wifidb to be on safer side.

Code Block

language	bash

 rm /opt/secure/wifi/*

8. Restart OneWifi to take effect.

Code Block

language	bash
title	Restart services

systemctl restart onewifi

9. EM-Controller can be executed manually in new tab.

Code Block

language	bash
title	Running EM-Controller

cd /usr/ccsp/EasyMesh/

→ In the cli use "Tab" to move between Update, Apply and Cancel button in the cli, use keys "j" and "k" to scroll up and down
→ Select "Wifi Reset" and then select Update to update the window.
→ In the CollocatedAgentID update the Mac address of the brlan0(a2:f0:d1:69:f5:ae) which needs to be treated as AL MAC..
→ Select Apply to reset the database.

Change colocatedAgentID with brlan0 MAC address which needs to be treated as AL MAC

12. Run local Agent manually with below command in new tab.

Code Block

language	bash

cd /usr/ccsp/EasyMesh/
onewifi_em_agent

Workaround: Initially, EM-Agent and EM-Contrller processes will not be in sync . Need to do restart the both EM-Agent and EM-Controller processes for 1st time alone.

Code Block

language	bash

killall onewifi_em_agent
killall onewifi_em_ctrl

Re-run EM-Controller in controller tab.

Re-run EM-Agent in Agent tab.

Observation in EM-Contrller device side:

All configured VAPs should be UP and Running
VAPs should be broadcasting EasyMesh default SSIDs(eg, private_ssid, mesh_backhaul)

Extender1

Prerequisites - One Time Process

Delete the dnsmasq binary.

Code Block

language	bash

rm /usr/bin/dnsmasq

2. Remove default gw entry from routing table since WAN access will be through backhaul connection.

Code Block

language	bash

route del default gw

6. Remove default onewifi db from /opt/secure/wifi to be on safer side.

Code Block

language	bash

rm /opt/secure/wifi/*.db

7. Restart OneWifi

Code Block

language	bash

systemctl restart onewifi

8. Ensure mesh backhaul connectivity is established over 5G through wifi1.1 interface.

Code Block

language	bash

iw dev wifi1.1 info

9. Verify mesh backhaul connection in EM-Contrller side as well.

Code Block

language	bash

10. Upon successful backhaul connectivity, run EM-Agent in Extender1 in new tab.

Code Block

11. Wait for few minutes( for Agent to propagate SSID information from Controller to OneWifi in Extender1) and then check

Check all configured VAPs should be up and running with "iw dev" command
VAPs should be broadcasting default EasyMesh SSIDS (ie private_ssid, mesh_backhaul)

12. Set static IP for brlan0 interface in Extender1

Code Block

language	bash
