Network Commands Reference Guide
The ultimate CLI cheat-sheet for Cisco, Juniper & Huawei — 500+ commands, 40+ sections, one document.
Cisco IOS / IOS-XE
Juniper JunOS
Huawei VRP

01 — Introduction
Why Every Network Engineer Needs This Reference
Whether you are preparing for a certification exam, troubleshooting a live production network at 2 AM, or onboarding onto a new project that mixes vendors, the single biggest time-sink is switching between three completely different CLI paradigms — Cisco IOS, Juniper JunOS, and Huawei VRP. The syntax is different, the logic is different, and even the mental model of how configuration works differs significantly between them.
At IT.connect4techs.com, we built this document to solve exactly that problem. Instead of keeping three browser tabs open, bookmarking dozens of scattered documentation pages, or flipping between vendor-specific study guides, you get one clean, well-organized PDF that covers all three platforms side by side.
💡 Who Is This For?
This guide is written for network engineers, system administrators, NOC teams, students preparing for CCNA/CCNP/JNCIA/HCIA and above, and anyone who regularly interacts with multi-vendor network environments.
From basic interface configuration to advanced BGP policies, IPSec VPNs, and QoS traffic shaping — everything is covered, formatted consistently, and ready to use the moment you open the file.
02 — Overview
What Is the Network Commands Reference Guide?
The Network Commands Reference Guide is a professionally formatted PDF document designed as a quick-reference companion for network engineers working with enterprise and service-provider equipment. It is organized by functional category — not by vendor — so you can find what you need instantly without knowing which vendor’s documentation to open first.
Each command entry includes the exact syntax and a plain-English description of what it does. The document ends with a comprehensive side-by-side comparison table that maps equivalent operations across all three vendors — making it invaluable for engineers transitioning between platforms or managing a mixed-vendor environment.
✅ Document Format
High-resolution PDF — printable in color or greyscale. Every page carries the
IT.connect4techs.com brand header and footer with page numbers for easy offline navigation.
03 — The Content
What’s Inside — A Detailed Breakdown
The guide is divided into three major vendor chapters, followed by a cross-vendor comparison appendix. Here is a representative sample of the sections covered under each platform:

▸Static Routing & Default Routes
▸OSPF (v2 & v3)
▸EIGRP
▸BGP (eBGP & iBGP)
▸VLANs & Trunking
▸Spanning Tree Protocol
▸EtherChannel / LAG
▸HSRP / VRRP / GLBP
▸ACLs (Standard & Extended)
▸NAT / PAT
▸DHCP Server & Relay
▸SSH & AAA Security
▸QoS & Traffic Shaping
▸IPSec VPN & GRE Tunnels
▸Monitoring & Diagnostics
🟢 Juniper JunOS
▸CLI Basics & Commit Workflow
▸Interface Configuration (MX/EX/QFX)
▸Static Routing & RIB
▸OSPF with Policy Export
▸BGP Groups & Route Policies
▸EX-Series VLANs & IRB
▸Firewall Filters (ACLs)
▸NAT (SRX Platform)
▸Security Zones & Policies
▸MPLS & LDP
▸Monitoring & Live Capture
🔴 Huawei VRP
▸System View Navigation
▸Interface Configuration (NE/S-Series)
▸Static & Default Routing
▸OSPF (Area & Authentication)
▸BGP Peer Groups & Policies
▸VLANs & SVI (Vlanif)
▸STP & Link Aggregation (Eth-Trunk)
▸ACL (Basic & Advanced)
▸NAT & DNAT Port Mapping
▸DHCP Server & Relay
▸SSH & AAA (STelnet)
▸QoS Traffic Classification
▸IPSec & GRE Tunnels
▸Hardware Health & Diagnostics
Quick Cross-Vendor Comparison Snapshot
Here is a small excerpt from the comparison table included at the end of the document:
| Operation | Cisco | Juniper | Huawei |
|---|
| Save Config | copy run start | commit | save |
| Show Interfaces | show ip int brief | show int terse | display ip int brief |
| Show Routing Table | show ip route | show route | display ip routing-table |
| Enable Interface | no shutdown | delete int ge-0/0/0 disable | undo shutdown |
| Show OSPF Neighbors | show ip ospf neighbor | show ospf neighbor | display ospf peer |
| Reboot Device | reload | request system reboot | reboot |
⚡ Bonus — Appendix
The final appendix contains a full 20-row cross-vendor comparison covering everything from VLANs and DHCP to BGP and NAT — one of the most time-saving references in the entire document.
04 — Why This Document
Six Reasons Engineers Keep This PDF Open
🚀
Speed During TroubleshootingWhen a network is down, every second counts. Instead of Googling syntax or pulling up three separate vendor docs, you open one file and find the command in seconds.
🌐
Multi-Vendor Environments Are the NormMost enterprise and service-provider networks run a combination of Cisco, Juniper, and Huawei equipment. This document bridges all three in one consistent format.
🎓
Certification Exam PreparationWhether you are aiming for CCNA, CCNP, JNCIA, JNCIS, HCIA, or HCIP, having all core commands organized by technology makes revision dramatically more efficient.
🔄
Platform Migration ProjectsWhen migrating from Cisco to Huawei (or any other combination), the side-by-side comparison table lets you instantly identify the equivalent command on the target platform.
🧑💼
Perfect for NOC & Help-Desk TeamsEven team members who are not deep networking specialists can use this reference to run diagnostics, check status, or follow a runbook without needing expert knowledge.
📴
Works OfflineA PDF works anywhere — on a laptop in a data center with no internet access, printed on paper in a remote site, or stored on a USB stick for field work.
05 — Conclusion
Your Network Career, One PDF Smarter
The Network Commands Reference Guide is not just another cheat sheet. It is a carefully curated, professionally formatted resource that respects your time — built by engineers, for engineers. Whether you are a fresh CCNA candidate learning the ropes or a seasoned architect managing a global multi-vendor backbone, this document has something for you.
We designed it to be the kind of reference you keep bookmarked on your browser, saved on your desktop, and possibly printed and pinned above your workstation. It is the document we wished existed when we were learning networking — so we built it ourselves and are sharing it freely with the community.
At IT.connect4techs.com, our mission is to make high-quality networking knowledge accessible, practical, and free. This guide is one part of a larger library of resources we are building for the network engineering community. Stay tuned for upcoming guides on MPLS, SD-WAN, network automation with Python & Ansible, and more.
