Highlight Sets Cisco Best __link__: Xshell

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.

    1. Recommended Solution: Creating a "Best Practice" Cisco Highlight Set

    To achieve optimal visibility, follow these steps to configure a custom highlighting set tailored for Cisco CLI output. xshell highlight sets cisco best

    Step 3: Assign the Set to Your Cisco Session

    • In the session properties (File > Properties), go to Terminal > Highlighting.
    • Choose your imported Cisco set from the dropdown.
    • Check "Enable keyword highlighting".

    Step-by-Step: Build Your Cisco Highlight Set

    1. Open Xshell Highlighting Settings

    • Go to Tools > Highlight Sets (or Alt + H).
    • Click New to create a set called Cisco Best.
    • Action: On the Cisco device CLI, type: 
      terminal color
      (Note: In config mode, you can use line console 0 -> terminal color to make it permanent on some platforms).
    • Xshell Requirement: Ensure Xshell is set to use XTerm or Linux terminal emulation (Session Properties > Terminal > Terminal Type = xterm or linux).
    • Pros/Cons: This provides automatic coloring by the device itself, but it is less customizable than Xshell's highlight sets.

    Highlight Sets are a critical productivity feature for Cisco network engineers, allowing for the automatic color-coding of terminal output. This helps quickly identify errors, up/down statuses, and specific IP addresses in a sea of scrolling text. Best Practice Configuration for Cisco Xshell is a popular SSH client for Windows

    : Highlighting words like "BGP," "OSPF," or "EIGRP" to separate routing logic visually. Setting Up the "Best" Cisco Highlight Set To create an optimal set in Tools > Highlight Sets and add keywords relevant to Cisco IOS: Error Indicators (Red) : Add keywords like err-disabled administratively down . This ensures critical failures jump out immediately. Positive Status (Green) established to confirm health at a glance. Configuration Logic (Cyan/Yellow) : Highlight access-list to help navigate large configuration files. Critical Alerts (Bold/Orange) : Highlight to monitor transient issues. Why Xshell's Highlighting Beats Alternatives While some engineers use external tools like ChromaTerm or specialized Visual Studio Code packages Pattern: (
