Below, you'll find the commands in code-blocks as well as a nifty PDF that you can print off to hang on your wall and show off to all your friends! *(if thats your thing)* [Juniper Networks General CheatsheetA nifty looking cheatsheet to hang on your wall.Juniper Networks General Cheatsheet.pdf104 KBdownload-circle](https://artofinfra.com/content/files/2025/07/Juniper-Networks-General-Cheatsheet.pdf "Download") ![Image displaying all the commands for our Juniper Networks Cheatsheet.](https://artofinfra.com/content/images/2025/09/Juniper-Switching-Cheatsheet.webp) Preview of the PDF Cheatsheet ## Operational monitoring commands ```bash > show interfaces terse -- Displays interface statuses and IPs. > show interfaces extensive -- Provides detailed statistics, errors, traffic, and physical interface information. > show interface description -- Shows interface descriptions and operational status. > show ethernet-switching table -- Displays MAC-address forwarding table. > show vlans -- Lists configured VLANs with IDs, names, and membership port counts. > show route -- Displays active routing-table entries, protocols, next-hops, preferences, current metrics values. > show arp -- Shows IP-to-MAC address mappings learned for Layer-3 neighbour resolution table. > show dhcp binding -- Displays DHCP bindings with lease times, MACs, and addresses allocated. > show ospf neighbor -- Shows OSPF neighbour states, IDs, interfaces and timers. > show bgp summary -- Summarises BGP peer sessions, prefixes, state and uptime. > show system uptime -- Displays current time, system boot duration, and protocol uptime statistics. > show system alarms -- Lists software or hardware alarm conditions. > show system processes extensive -– Displays CPU usage, memory, and state of all system processes. > show version -- Shows Junos OS build, model, serial number, and software versions. > show chassis hardware -- Displays chassis components, FPCs, PICs, serial numbers, and hardware inventory. > show chassis alarms -- Displays chassis-level environmental, power, or component alarms. > show chassis routing-engine -- Shows routing-engine CPU, memory, temperature, uptime, mastership information status details. ``` [Collecting Juniper RSI and Log Files for JTACDuring your time as a network engineer, you may be required to collect log files and RSI info to assist JTAC with investigations.
