Cisco command cheat sheets
Dense, printable command references for the CCNA — the exact Cisco IOS syntax you reach for, grouped by task and checked for accuracy. Bookmark one, keep it beside your terminal, then drill it on a graded lab.
Use these as a fast lookup, not a first read. Grab the sheet for whatever you're configuring, keep it open beside your terminal, and reach for it whenever the exact syntax slips. To turn memory into speed, pair the subnetting sheet with the subnetting practice drill until the math is automatic, then prove a real config passes on the free sample lab — no account, no card.
Want the full picture behind the commands? The CCNA study hub ties every topic's cheat sheet to its guides and graded labs in blueprint order, so you always know what to drill next.

Can I print these cheat sheets?
Yes. Each cheat sheet is built to print cleanly on a page or two — the site chrome is hidden when you print, so you get just the commands. Print one, keep it beside your terminal, and mark it up as you drill.
Are the cheat sheets free?
Completely free, with no account or sign-up. Bookmark any of them and use them as much as you like. When you want to prove the commands stuck, the free sample lab grades a real Cisco config with no card required.
Which cheat sheet should I start with for the CCNA?
Start with the IOS basics reference — navigating modes, interfaces, and show commands underpins everything else — then keep the subnetting sheet close, since subnetting is the single most-tested CCNA skill. From there, add the OSPF, VLAN, and ACL sheets as you reach those topics.
How current is the Cisco IOS syntax?
Every command is fact-checked against real Cisco IOS on the same free-tier images the labs run on, so the syntax matches what you'll type on the exam and in Cisco Modeling Labs.
Know the commands cold?
Drill the subnetting math to reflex, then prove a real Cisco config passes — no account, no card.
