Restore Edgecore factory default configuration since 202012.3 and above

Since 202012.3, Edgecore enhance Edgecore Default configuration file that's different than Community(Open Source) SONiC's T1/T2 configuration. 

• Removed Parts:
  • DEVICE_METADATA["localhost"]["bgp_asn"]
  • LOOPBACK_INTERFACE
  • BGP_NEIGHBOR
  • DEVICE_NEIGHBOR
  • INTERFACE - Ports are not assigned any IP by default.
• New added Parts:
  • REST_SERVER["default"]["client_auth"] = "user" - With this setting, users need to provide username/password to access the REST Server.
  • docker_routing_config_mode = "split" - With this setting, FRR uses split mode.
  • frr_mgmt_framework_config = "true" - With this setting, OSPF/ISIS features are enabled.

Step 1. Remove  /etc/sonic/config_db.json.

Remove:

admin@sonic:~$ sudo rm /etc/sonic/config_db.json

Step 2. Generate Edgecore factory default configuration by this command

admin@sonic:~$ sudo config-setup factory

Edgecore Default configuration file is restored on /etc/sonic/config_db.json now.

Step 3. Reboot device

admin@sonic:~$ sudo reboot

Generate the default configure through the Platform and the HwSKU information

Step 1: Check the $Platform and $HwSKU information

admin@sonic:~$ show platform summary
Platform: x86_64-accton_as7326_56x-r0
HwSKU: Accton-AS7326-56X
ASIC: broadcom

Step 2: Set the $Platform and $HwSKU information to environment variable. 

admin@sonic:~$ export Platform=x86_64-accton_as7326_56x-r0
admin@sonic:~$ export HwSKU=Accton-AS7326-56X

Step 3: Generate the default setting same as initial installed.

admin@sonic:~$ sudo sonic-cfggen -H -p /usr/share/sonic/device/$Platform/platform.json --preset t1 -k $HwSKU > ~/default.json

Step 4: Replace the "default.json" to the correct position.

admin@sonic:~$ sudo cp default.json /etc/sonic/config_db.json

Step 5. Config reload or power cycle the switch

admin@sonic:~$sudo config reload -y

Use the script "restore_202006.sh" to reset default

Upload and Execute the script restore_202006.sh on the SONiC  

The script generates default configuration config_db.json automatically.  Reboot the switch or reload configuration to take effect.(The script is applicable to 202006 branch and 202012 branch)

Step 1: Set the management IP

admin@sonic:~$ sudo config interface ip add eth0 192.168.10.1/24

Step 2: Upload the Script to the SONiC

admin@sonic:~$ sudo scp root@192.168.10.2:/root/restore_202006.sh ~/  

Step 3: Change permission of script.

admin@sonic:~$ chmod +x restore_202006.sh

Step 4: Running the script.

admin@sonic:~$ ./restore_202006.sh

Step 5. config reload or power cycle the switch

admin@sonic:~$ sudo config reload -y

admin@sonic:~$ sudo mv /etc/sonic/config_db.json /etc/sonic/config_db.json.modified

admin@sonic:~$ show ztp
ZTP Admin Mode : False
ZTP Service : Inactive
ZTP Status : Not Started

ZTP Service is not running

admin@sonic:~$ sudo config ztp enable
Running command: ztp enable
admin@sonic:~$ sudo reboot

Step 4: Check the current SONiC's config folder.

admin@sonic:~$ sudo ls /etc/sonic/ | grep config_db.json
config_db.json.modified

Step 5: Disable ZTP function, and then check the SONiC's config folder.

admin@sonic:~$ sudo config ztp disable

Active ZTP session will be stopped and disabled, continue? [y/N]: y

admin@sonic:~$ sudo ls /etc/sonic/ | grep config_db.json
config_db.json
config_db.json.modified
admin@sonic:~$
