Cisco Nexus In-depth + Lab Demonstration | NetworkJourney

Explore the Cisco Nexus 9500 series architecture, including supervisor engine, system controller cards, and fabric modules that connect directly to line cards with no midplane or backplane. Learn power and redundancy options, including up to ten power supplies and modes—combined, N plus one, grid, and complete redundancy.

Explore Cisco Nexus data center switches across 9500, 9300/9200, and 7700 series, with optics and media basics, and practice lab work using GNS3 to emulate Nexus 9k.

Explore fiber types and transceivers in data centers, comparing multi-mode and single-mode fiber, cat 6a to 8.2, color codes, LEDs vs laser diodes, and 10/40/100 Gb transceivers with breakout options.

Explore Cisco transceiver compatibility, SFP28 25 gig optics, DAC and AOC cabling, and the Nexus 7700’s modular fabric architecture to design scalable data center networks.

Explore Cisco Nexus 7000 hardware architecture, including supervisor engines, fabric modules, line cards, and throughput, with a lab demonstration and Cisco catalog access.

Explore the Nexus 7000 architecture, including full-width supervisor engines, backplane-connected fabric modules, line cards, and note end-of-life timelines and VDC support.

Compare Cisco Nexus M-series and F-series line cards, highlighting layer 3 versus layer 2 functions, backplane routing, latency, fabric path, and compatibility with VXLAN, EVPN, and Trustsec.

Discover Cisco Nexus unified ports that can run Ethernet or fiber channel from the same port, with native L2 and L3 support on Gen 2 models and Ethernet defaults.

Explore nexus 5k port channels, dynamic pinning, static pinning, and VPC topologies, their redundancy and oversubscription tradeoffs, and basic configuration steps using facts, port channels, and host ports.

Explore NX-OS on Nexus 5K, learn feature-based licensing, enable features via feature commands, and configure VPC, fabricpath, FEX, OSPF, BGP, and MPLS.

Explore Cisco Nexus licensing and packaging, including fabric path packages, product IDs, smart account licensing, activation keys, and license installation workflows.

Explore how a Cisco Nexus boots from bootloader to Nexus OS, loading kickstart and system images. Learn upgrade best practices with install all, system switchover, and in-service upgrades.

discover how to allocate ports into VPC groups, assign interfaces by port ranges, and manage VPC resources (global, dedicated, shared) while applying default admin roles.

perform a layer 2 lab on nexus 9k devices, configuring vlan 5 through 15 and ensuring vlan exists before port assignment, while exploring nexus vlan handling and show vlan brief.

Configure VLANs across Nexus switches manually, implement MSTP with instance mapping, compare MSTP to rapid pvst, and apply port types such as edge and bridge assurance.

Enable bridge assurance by setting the port type to network on Nexus devices, so blocking ports send bpdu keepalives and prevent loops during unidirectional link failures, replacing loop guard.

Configure rapid pvst on Cisco Nexus, enable automatic VLAN pruning on trunks, set root bridge priorities across VLANs, and apply edge ports to user connections for loop protection.

Explore how private VLANs split a single VLAN into primary, community, and isolated sub VLANs on Nexus devices, enabling broadcast suppression and enhanced layer 2 security.

Configure and map private vlans 20, 30, and 40, associate 20 and 30 with 40, set up host and trunk ports, and assign 192.168.40.0/24 IPs to enable isolation.

Explore configuring Nexus port channels, bundling multiple interfaces into a single logical interface, using static and LCP modes, with hands-on steps for port channels 12 and 13 and load balancing.

Learn to configure layer 3 routing on Nexus devices using named mode, ipv4 unicast, and an autonomous system to advertise loopbacks for out-of-band management.

Learn to configure and verify Cisco Nexus devices, log to console, establish IP neighbor and show commands, and configure OSPF and BGP for IPv4 unicast.
