Ethernet Management Interface

This page describes how to configure management interfaces.

Example model & SONiC version:

• Aurora 721
• Netberg SONiC: sonic-broadcom-202311.n0

Serial Management Interface

Default serial settings in Netberg SONiC are 115200-8N1,

All initial configuration can be done using the serial connection.

Example:

minicom -D /dev/ttyUSB1 -b 115200

Ethernet Management Interface

Default settings:

• All Netberg models will name management port “eth0”

• DHCP address on management port”eth0″

• Configure IP address on management port “eth0”

admin@nba721:~$ sudo config interface ip add eth0 192.168.0.133/24 

admin@nba721:~$ sudo config interface ip add eth0 2001::8/64

• Check IP addresses

admin@nba721:~$ show ip interfaces

Save settings to config_db.json

admin@nba721:~$ sudo config save -y

Check IP address setting in config_db.json

admin@nba721:~$ sudo nano /etc/sonic/config_db.json
