After testing dozens of public sets (Reddit, GitHub, Cisco Learning Network) and building my own over 8 years, the set must have:
Using Xshell’s is a game-changer for network engineers managing Cisco devices. Highlighting critical keywords like down , err-disable , or protocol can prevent configuration errors and speed up troubleshooting. 🛠️ How to Create a Cisco Highlight Set Go to Tools > Terminal Highlight Sets . Click New and name it "Cisco Best". Click Add to enter your keywords or regex patterns.
Open your Cisco session properties ( File > Properties ), go to the Appearance category, and select your newly created Cisco_Optimal_Colors from the Highlight Set dropdown menu. Advanced Pro-Tips for Cisco Highlighting Order of Precedence Matters
Managing Cisco devices via Command Line Interface (CLI) involves scanning thousands of lines of configuration data, routing tables, and interface statuses. Visual fatigue can lead to critical oversights, such as missing a "shutdown" status or misreading an IP address.
Instantly locate "down/down" states, protocol mismatches, or high CPU warnings without reading line-by-line. xshell highlight sets cisco best
1️⃣ Red (Bold): Keywords like error , denied , fail , invalid . Why? You need to know immediately if a command didn't stick.
Use the pattern (GigabitEthernet|TenGigabitEthernet|FastEthernet|Tw|Gi|Te|Fa)\d+(/\d+)* to automatically color-code interface naming conventions. Maintenance and Portability
These words confirm that protocols are functioning, interfaces are active, and configurations have been successfully applied.

Below is a ready-to-use set of regex patterns and colors for Xshell. These mimic Cisco’s native severity levels and common syntax.
Download the template rules from this article, import them into Xshell, and run show log on your nearest Catalyst switch. You’ll see the difference immediately.
The real magic happened when he began a complex BGP configuration. In the past, tracking autonomous system numbers and neighbor IPs was a game of squinting and double-checking. Now, the XShell highlight set automatically flagged and Access Lists . If he made a syntax error that didn't match the Cisco standard, the lack of color was an instant silent alarm.
The most effective sets prioritize "actionable" information—status changes, errors, and configuration boundaries. : UP : Bright Green (Signifies operational state). DOWN : Bright Red (Immediate attention required). Click New and name it "Cisco Best"
