Xshell Highlight Sets Cisco May 2026

| Issue | Likely Fix | |-------|-------------| | Highlight not appearing | Check that the session’s Terminal type is xterm or ansi (not VT100). | | Pattern matches too much | Use word boundaries (\bdown\b instead of just down). | | Logs not highlighted | Ensure log viewer also references the same highlight set (set in log viewer settings). |


In the Options window, look for the Highlight tab or section. This is where you can configure what gets highlighted and how.

These demand attention but don't require immediate panic.

Visualizing Your Cisco CLI: A Guide to Xshell Highlight Sets xshell highlight sets cisco

Tired of staring at endless walls of monochromatic text in your Cisco terminal? Using Xshell Highlight Sets can transform your workflow by making critical information like IP addresses, status keywords, and errors pop out instantly. Why Use Highlight Sets for Cisco?

Unlike standard color schemes that change the entire terminal's background or text color, Highlight Sets use string matching and regular expressions to colorize specific parts of the output.

Faster Troubleshooting: Catch "down" interfaces or "err-disable" states in red immediately.

Reduced Eye Strain: Distinct colors for interface names, IP addresses, and command prompts make logs easier to parse.

Visual Consistency: Ensure that crucial data like BGP summaries or route maps look the same across every device you manage. How to Create Your Cisco Highlight Set
