SONIC Operation and Commands - amybuck/SONiC-NAS GitHub Wiki

This information describes the standard Linux Debian distribution operation and commands for the SONiC Host-Adapter package.

Log into Switch

The default admin username is part of the Linux sudo group for executing privilege commands. The default password is admin but you must change the password the first-time you log into the device. Before continuing, verify you have connected to the serial console on the device.

Mangement Interface

The Management port name is eth0, and the Management interface is configured to automatically obtain its IP address using DHCP by default. You can change the behavior by modify the /etc/network/interfaces file with the following parameters:

auto eth0
iface eth0
inet static address 10.11.133.40
netmask 255.255.0.0
gateway 10.11.133.254

After modifying the interfaces file, restart the networking service:

$ service networking restart

Manage System Services

Use the service _servicename_ status command to check the status of the service. The command output indicates if the service is up and running or inactive. You can also use the systemctl command to check the service status.
