Prove you have the skills to diagnose, restore, repair, and replace critical Cisco routers, switches, and operating environments at customer sites with the Cisco Certified Support Technician (CCST) Networking certification.
As a Cisco Certified Support Technician (CCST), you work closely with the Cisco Technical Assistance Center (TAC) to quickly and efficiently resolve networking support incidents.
Identify Cisco router and switch models, accessories, cabling, and interfaces, understand IOS operating modes, and use the Cisco CLI to connect and service products.
Understand TCP/IP, OSI models, network types, and cloud vs. on-prem services.
Work confidently with IPv4 subnetting, IPv6 prefixes, and NAT concepts.
Identify cables, connectors, ports, and endpoint devices used in LANs.
Explain basic routing, VLANs, and MAC address tables, and operate the Cisco CLI.
Run ping, traceroute, and nslookup, and analyze traffic with packet captures.
Configure firewalls, AAA, MFA, and wireless security with WPA2/WPA3.
The curriculum tracks the official CCST Networking blueprint, covering fundamentals, addressing, hardware, device operations, and troubleshooting.
Understand the building blocks of networks, network types, cloud services, and common protocols.
Identify IPv4 and IPv6 addressing, subnet formats, and broadcast domains.
Identify cables, connectors, device ports, status lights, and common endpoint devices.
Explain basic routing and switching concepts and operate Cisco devices via the CLI.
Apply troubleshooting methodologies, run diagnostics, and configure basic network security.
Expand each domain to see the networking concepts, hardware, and CLI skills you will master throughout the course.
CCST Networking is the entry point into a wide range of field support, NOC, and junior administration roles.
Provide onsite support and maintenance for Cisco routers, switches, and networks.
Install, diagnose, and replace network devices at customer sites.
Resolve connectivity and configuration issues for end users and infrastructure.
Support day-to-day operation and troubleshooting of small to mid-size networks.
Follow a hands-on progression that builds your networking foundation from core concepts through addressing, hardware, and troubleshooting.
Learn the OSI/TCP-IP models, network types, and common protocols.
Master IPv4 subnetting and IPv6 addressing concepts.
Identify cables, connectors, ports, and endpoint devices.
Run CLI commands, diagnose issues, and apply basic security — then sit the exam.
Exam domains and weightings are based on Cisco's official CCST Networking page.
