By implementing the regex patterns and advanced triggers detailed above—specifically for errors, interface states, and dynamic routing—you turn Xshell into a smart assistant that highlights only what matters.
(line protocol is down)$ - Anchoring to the end of line ( $ ) is computationally cheap. xshell highlight sets cisco
Do you have a specific Cisco platform (ASA, Nexus, IOS-XE) that needs a custom highlight? Tweak the %[A-Z]+-\d pattern to match your platform's syslog ID. By implementing the regex patterns and advanced triggers
Spend 15 minutes today migrating from the default black-and-white terminal. Import the XML set above, adjust the colors for your lighting conditions (dark mode users prefer brighter purples and oranges), and restart your Xshell session. You will never go back to plain text again. Tweak the %[A-Z]+-\d pattern to match your platform's
.*down.* - This triggers on every line, causing a performance nightmare.
For network engineers, spending hours staring at a black-and-white terminal while debugging a BGP flapping or tracing a faulty OSPF adjacency is not only tedious but inefficient. Color coding is not just about aesthetics; it is about cognitive load reduction. When configured correctly, color highlights can help you spot errors, identify IP addresses, and parse configuration changes in a split second.
