Build solid networking fundamentals on Dell Technologies products — from switch basics and Ethernet protocols through IP routing, services, security, operations, and Smart Fabric automation.
Module 01
Networking Essentials
›Purpose and function of network devices — switches (Layer 2 forwarding, MAC table learning) and routers (Layer 3 routing, ARP)
›Interface options — copper (RJ-45 1G/10G), SFP+ (10G), QSFP28 (100G), and DAC/AOC direct attach cables
›Cabling options — Cat5e/Cat6/Cat6A UTP, single-mode vs multi-mode fibre, and cable distance limits per standard
›Layer 3 forwarding logic — routing table longest-prefix match, administrative distance, and CEF forwarding on Dell OS10
›Static routing — ip route configuration, floating static routes, and next-hop vs exit-interface syntax
›Dynamic routing overview — OSPF (link-state, area design, adjacency) and BGP (eBGP peer configuration) on OS10
Module 04
Network Services
›DHCP — DHCP server configuration on Dell OS10 (pool, default-gateway, DNS), DHCP relay agent (ip helper-address), and verifying leases
›DHCP troubleshooting — client not receiving IP, stale lease, and rogue DHCP server detection
›NTP operation — stratum hierarchy, NTP server vs client mode, authentication, and clock synchronisation impact on syslog timestamps
›NTP configuration and verification — ntp server command, show ntp status, and best practices for redundant NTP sources on Dell switches
Module 05
Security Essentials
›Switch access security — console/VTY line password, SSH key generation, disable Telnet, and management ACL to restrict admin access by IP
›Local authentication — username/password configuration, privilege levels (0–15), and role-based access control on Dell OS10
›ACL fundamentals — standard ACL (source IP match), extended ACL (source/dest IP + port), named vs numbered ACLs
›ACL configuration and application — ip access-list, permit/deny rules, applying to interface (in/out), and verifying with show ip access-lists
›MAC-based security — port security (sticky MAC learning, violation actions), 802.1X port authentication overview
Module 06
Network Operations
›File transfer — copying config/firmware to/from switches using TFTP, SCP, and USB on Dell OS10; backup running-config to startup-config
›Common connectivity issues — duplex mismatch, VLAN misconfiguration, STP loop, routing table missing, and MTU mismatch diagnosis steps
›Switch OS upgrade procedure — download firmware image, verify checksum, schedule maintenance window, copy to flash, set boot image, and reload
›SNMP monitoring — SNMPv2c vs SNMPv3, community string / USM user config, enabling SNMP traps, and integration with Dell OpenManage or third-party NMS
›Syslog and logging — logging severity levels (0-Emergency to 7-Debug), remote syslog server config, and using logs for fault correlation
Module 07
Automation
›Smart Fabric Services (SFS) — purpose of fabric automation, zero-touch provisioning (ZTP) for Dell PowerSwitch, and SmartFabric Director overview
›SFS advantages — automated VLAN and port configuration propagation, reduced human error, and faster deployment vs manual CLI-based configuration
›REST API on Dell OS10 — RESTful API endpoint structure, GET/POST/PUT/DELETE methods for switch configuration, and JSON response parsing
›Ansible for Dell Networking — Dell OS10 Ansible modules (os10_command, os10_config, os10_facts), inventory file setup, and sample playbook for VLAN automation

Full Curriculum
7-Module D-NWG-FN-23 Programme
Complete networking foundations curriculum — from switch essentials and Ethernet protocols through IP routing, services, security, operations, and fabric automation.
›Purpose and function of switches (Layer 2 MAC forwarding, VLAN segmentation) and routers (Layer 3 IP routing, default gateway)
›Interface types — 1G/10G/25G/100G copper and fibre, SFP+/QSFP28 transceivers, DAC/AOC cables, and distance limitations
›Initial Dell OS10 switch configuration — console access, hostname, management IP (out-of-band vs in-band), SSH key generation, and NTP source
›Ethernet addressing — MAC OUI structure, dynamic MAC learning, CAM table flooding vs unicast, and broadcast domain boundaries
›VLANs — 802.1Q tag structure, access port (untagged), trunk port (tagged), native VLAN, voice VLAN, and inter-VLAN routing via SVI
›STP/RSTP — BID root bridge election, port state machine (Blocking→Listening→Learning→Forwarding), PortFast, BPDU Guard, and Root Guard
›LAG/LACP — LACP state machine, active vs passive mode, load balancing (src-dst-mac/ip), and min-links for resilience
›Storage networking — DCB Priority Flow Control, ETS traffic classification, and iSCSI VLAN best practices on Dell PowerSwitch
›File transfer — copy tftp://server/image.bin flash:, SCP secure copy, USB file copy, and verify image integrity with MD5/SHA checksum
›Connectivity troubleshooting toolkit — ping, traceroute, show interface (input/output errors, CRC), show mac address-table, show ip route, and show spanning-tree
›OS upgrade procedure — download new OS10 image, verify MD5, configure boot system, schedule maintenance window, reload, and post-upgrade validation
›SNMP v2c configuration — snmp-server community public ro, snmp-server host, enable traps (link-up/down, config change), and integration with Dell OpenManage
›Syslog and diagnostics — logging buffered 4096, show logging, remote syslog (logging host), and using tech-support bundle for TAC escalation
