Aviz Certified SONiC Professional (Preparatory Course)

Explore sonic architecture as a microservice-like platform where applications run in containers atop a Linux kernel, with Redis as the state API and PSI translating commands to hardware.

Explore how Redis db orchestrates Sonic's microservice architecture, linking config db, app db, hdb, state db, and counters db in a resilient, loosely coupled pipeline from config to ASIC.

Explore pmon, the platform monitor container that watches fans, power supplies, sensors, transceivers, and leds, then exposes health data via cli, snmp, and telemetry while remaining read-only.

Understand how Sonic's FRR-based routing container separates config, learning, decision, and handoff; BGP and zebra manage routes, while FPM sync pushes updates to the app db for hardware forwarding.

Explore the three-part flow of managers, sinks, and the orc agent in sonic, translating config to the Linux kernel and reporting real-world status. Witness how the orc agent is event-driven, never touches the kernel, and writes final hardware instructions to the sonic database for resilient operation.

Log in to the sonic device via ssh as admin, view version and images with show version and show boot, and set the next boot using sudo sonic_installer.

Learn SONiC port and interface commands, including show ip interface and show int status, to view layer 3 interfaces, admin and operational status, and manage eth0.

Configure a device from scratch by editing the config db json, saving the configuration, and changing the management interface, hostname, and IP address.

Explore LLDP commands to view neighbor connections, such as show ldp table and show ldp neighbors, detailing interface mappings, device names, system descriptions, and bridging and routing capabilities.

Understand the config_db.json startup file in sonic, including device metadata and port configurations, and learn how CLI or json edits are persisted with config save after a reload.

Learn to incrementally merge configurations with the config load command, updating the running configuration without restarting dockers and then save changes to config db.json, such as adding a vlan.

Learn to validate the configuration file config_db.json for Sonic devices, fix line 83 syntax comma errors, and use the sonic command to verify formatting before applying.

Configure IP addresses on device interfaces to place device one and device two in the same subnet 10.3.3.1/24 and 10.3.3.2/24, then verify connectivity with a ping.

Learn to change an interface speed with sudo config interface speed, verify via show interface status, and resolve mismatched speeds across topology to restore up communication.

Change and verify the port MTU in Sonic using cli and config db approaches, switching between 7000 and 9000 while validating with show interface status and Docker checks.

Learn to use the show interface counter command to view interface status, traffic, and errors, and how to clear counters to debug traffic and identify drops in sonic devices.

Learn to configure VLANs on the device by adding VLAN ten, assigning and removing members in tagged and untagged modes, and deleting VLANs with CLI commands.

Configure an SVI to assign an IP address to VLAN ten and make Ethernet 32 a member, enabling layer 3 routing and pinging across devices.

Configure SVI with tagged mode on VLAN ten and VLAN twenty using Ethernet 32, assign IPs 10.331/24, 10.332/24, 20.331/24, and 20.332/24, and verify with show commands.

configure a port channel 200 as a vlan member, create svi for vlan 200 and 210 with ip addresses 10.3.3.1/24 and 10.3.3.2/24, and verify traffic with pings and interface status.
