Best: Xshell Highlight Sets Cisco
Most default Xshell themes are either monochrome (green-on-black retro terminals) or garish (default PowerShell colors). Neither works for Cisco. The best sets use a traffic-light + exception model:
A bad set colors everything blue. A good set respects the severity hierarchy.
If Xshell doesn’t support Cisco syntax directly or through community profiles, consider:
Xshell’s highlight sets are underutilized magic for Cisco engineers. Spend 10 minutes setting this up once, and every hour you spend on the CLI becomes more readable, less error-prone, and almost enjoyable.

Happy (colorful) CLIing!
Configuring Xshell Highlight Sets for Cisco devices transforms a dense wall of text into an easily readable, actionable dashboard. By applying specific colors to keywords like "Interface," "UP," or "Error," you can identify critical status changes in seconds. Why Highlighting Matters for Cisco CLI
A standard Cisco terminal is monochrome, making it easy to miss a single "down" or "denied" line in a long show run or show log. Effective highlighting:
Reduces Cognitive Load: Your eyes naturally jump to color-coded critical status indicators. A bad set colors everything blue
Speeds Up Troubleshooting: Errors, drops, and interface shutdowns stand out immediately.
Safety: Highlights like "Shutdown" or "No" help prevent accidental configuration mistakes. Step-by-Step Implementation in Xshell
Xshell allows you to create custom rules that trigger colors based on specific text patterns. Open the Highlight Editor: Go to the Tools menu and select Terminal Highlight Sets. Create a New Set: Click New and name it "Cisco Best Practices". Add Keyword Rules:
Click Add to enter a keyword and choose its color. Use "Regular Expression" mode for advanced matching (e.g., matching IP addresses). Activate the Set: Happy (colorful) CLIing
Once created, right-click your active terminal session, go to Highlight, and select your new Cisco set. Recommended "Best Practice" Highlight Rules
For a professional Cisco setup, use this categorization to color-code your terminal: Keyword Examples Recommended Color Critical Errors Error, Fail, Down, Disabled, Deny Bright Red Active/Positive Up, Established, Success, Permit, Active Bright Green Interface/ID GigabitEthernet, TenGigabit, Vlan, Serial Cyan or Blue Warnings Warning, Full, BPDUs, Collision, Discard Yellow / Orange Configuration interface, router, access-list, ip route Magenta or Purple Data Types IP Addresses (Regex: \d1,3(\.\d1,3)3) Light Gray / Bold Pro-Tips for Xshell Users
Case Sensitivity: Most Cisco commands are case-insensitive, but logs can vary. Ensure your Xshell rules are set to ignore case to capture both down and DOWN.
Regex for IPs: Use the regular expression \b(?:\d1,3\.)3\d1,3\b to highlight all IPv4 addresses in a neutral color like Gray to make them pop without being distracting.
Background Highlighting: For extreme warnings like "ADMINISTRATIVELY DOWN," set the Background Color to Red so the entire line glows.
Xshell is a popular SSH client for Windows that allows users to connect to remote servers and manage them. It supports syntax highlighting for various programming languages and configurations, including Cisco IOS.
