Xshell Highlight Sets Cisco

Imagine a scenario: Your monitoring system says "BGP Peer 10.0.0.1 down." You SSH into the Cisco router using Xshell.

Without Highlights:

BGP neighbor 10.0.0.1 remote AS 65001
BGP neighbor 10.0.0.1 state Idle
BGP neighbor 10.0.0.1 uptime 00:00:00
% BGP-3-NOTIFICATION sent to 10.0.0.1 (hold time expired)

You have to read every line.

With your Xshell Cisco Highlight Set:

In one glance, you know:

Resolution time: 30 seconds.

Once you have perfected your Cisco highlight set, share it with your NOC team.

Your team members simply import the file, and they instantly benefit from the same visual syntax parsing.

You can manually create a .ini file or ask Netsarang community for pre-built sets.
Xshell highlight sets are stored in:

%APPDATA%\NetSarang\Xshell\HighlightSets\

Create Cisco.ini:

[Set]
Name=Cisco
[Keywords]
0=enable,0,0,0x00AAFF
1=configure terminal,0,0,0x00AAFF
2=interface,0,0,0x00AAFF
[Regex]
0=\b([0-9]1,3.)3[0-9]1,3\b,0x00FF00,0,0
1=(Gi|Fa|Te|Et)[0-9]/[0-9]+,0xFFFF00,0,0

Restart Xshell to load it.

You can attach highlight sets to specific sessions. Right-click a session > Properties > Advanced > Highlight Set.

If you connect to newer Cisco devices (like Nexus switches or IOS-XE) that output colors automatically, ensure Xshell is not stripping them:

Pro Tip: If you want to highlight configuration lines that are simply "active" (not negated), use the regex ^[^ !no].* to match lines that do not start with a space, exclamation mark, or the word "no". This effectively highlights active configuration commands.

Xshell Highlight Sets for Cisco devices allow you to visually distinguish critical commands, interface statuses, and configuration errors in real-time, significantly reducing human error during network troubleshooting. By defining specific colors for keywords like "UP," "DOWN," or "err-disable," network engineers can parse dense CLI outputs at a glance. How to Configure Cisco Highlight Sets in Xshell

Setting up a custom highlight set in Xshell is a straightforward process accessible through the Tools menu.

Access the Dialog: Navigate to Tools > Terminal Highlight Sets. xshell highlight sets cisco

Create New Set: Click New, name your set (e.g., "Cisco_Highlighter"), and click OK. Add Keywords: Click Add to enter specific words or regular expressions.

Example: Use \bDOWN\b to highlight the word "DOWN" only when it appears as a whole word.

Assign a color (e.g., bright red) and font style (e.g., bold) to the keyword. Apply to Sessions:

Current Session: In the Highlight Sets dialog, select your set and click Set to Current.

Permanently: Open Session Properties > Appearance and select your "Cisco" set from the Highlight Set dropdown menu. Recommended Highlight Patterns for Cisco IOS

The following patterns are commonly used by network engineers to improve CLI readability: Recommended Keyword/Regex Color Suggestion Status: Up up, established, connected Emerald Green Status: Down down, shutdown, administratively down Bright Red Errors err-disable, error, CRC, collision Bold Red or Orange IP Addresses \b(?:[0-9]1,3\.)3[0-9]1,3\b Cyan or Light Blue Interfaces (Gi|Fa|Te|Et)[0-9]/[0-9]+ User/Auth password, secret, username Advanced Tips for Networking Pros

Use Regex Engines: Xshell utilizes the Perl-compatible DEELX engine. Ensure you check the Regular Expression box when adding complex patterns like MAC or IP addresses to ensure they match correctly.

Avoid "Christmas Tree" CLI: Too many colors can be distracting. Stick to a dark background (like the "Jellybeans" scheme) with high-visibility neon colors reserved strictly for status indicators and errors.

Team Sharing: You can export your highlight sets to share with colleagues, ensuring your entire engineering team uses the same visual standard for troubleshooting.

Terminal Type Sensitivity: If colors do not appear, ensure your terminal type is set to xterm or vt320 in the session properties.

Visualizing Your Cisco CLI: A Guide to Xshell Highlight Sets

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

Setting up your own custom highlighting in Xshell is a straightforward process through the tools menu.

Open the Highlight Dialog: In Xshell, navigate to the Tools menu and select Terminal Highlight Sets.

Create New: Click the New button and give your set a name like "Cisco_IOS". Imagine a scenario: Your monitoring system says "BGP Peer 10

Add Keywords: Click Add to input the strings or patterns you want to emphasize.

Status Indicators: Add up, down, administratively down, and shutdown.

Networking Patterns: Use basic strings or regular expressions for IPv4 addresses.

Assign Styles: For each keyword, choose a foreground color (e.g., Red for "down", Green for "up") and font style (e.g., Bold).

Apply to Sessions: Select your new set in the Highlight Sets dialog and click Set to Current to activate it for your active session. Recommended Colors for Cisco Devices

A well-organized set avoids "color vomit" and focuses on utility: Red: down, shutdown, err-disable, error, no. Green: up, established, connected, and IP addresses.

Blue: Interface names (e.g., GigabitEthernet, Te0/0/1) and switchport commands. Yellow: User accounts, hostnames, or specific warning logs. Pro Tip: Share Your Sets

Once you've perfected your Cisco highlight set, you can export/import the configuration files to share with your team, ensuring everyone sees the same visual cues during high-pressure troubleshooting. danielmacuare/netcli-highlight - GitHub

Examples * BGP Summary (Cisco / Arista) * Interface Status (Cisco / Arista / JunOS) * Route Maps (Cisco / Arista) * Prefix Lists (

In network administration, speed and accuracy are everything. When you're staring at hundreds of lines of Cisco IOS output, crucial details like IP addresses, interface statuses, or "shutdown" commands can easily get lost in a sea of monochrome text. This is where XShell’s Highlight Sets become a game-changer.

By configuring custom highlight sets for Cisco environments, you transform a flat text stream into a prioritized dashboard. Here is how it streamlines your workflow: 1. Instant Error Identification

The most powerful use of highlighting is for status keywords. Setting "down," "administratively down," "err-disable," and "failed" to a

background ensures that hardware issues or configuration errors jump off the screen during a show ip interface brief . You no longer have to scan—you simply look for the red. 2. Status Confirmation

Conversely, highlighting "up," "established," and "active" in

provides immediate psychological confirmation that a change was successful. When bringing up a BGP neighbor or an OSPF adjacency, seeing that flash of green confirms the state without needing to read the specific line. 3. Syntax and Variable Isolation

Network engineers often deal with complex regular expressions or long strings of IP addresses. You can configure XShell to highlight: IP Addresses: Using a regex pattern like \d1,3\.\d1,3\.\d1,3\.\d1,3

in a distinct color (like cyan) helps track traffic flow in debugs.

Highlighting "permit" vs. "deny" in ACLs prevents catastrophic oversights during security audits. Highlighting the hostname or the

prompt helps you keep track of which device you are currently configuring, reducing the risk of "fat-fingering" a command on the wrong router. 4. Reduced Cognitive Load You have to read every line

Human brains process colors faster than text. By offloading the "searching" task to XShell’s highlighting engine, you reduce the mental fatigue associated with long troubleshooting sessions. This allows you to focus on the logic of the network rather than the mechanics of reading the terminal. How to Implement To set this up, go to Tools > Highlight Sets

in XShell. Create a new set called "Cisco" and add your keywords and regex patterns. Once saved, you can assign this set to all your Cisco sessions under the Appearance tab of the session properties. Conclusion

XShell Highlight Sets aren't just an aesthetic preference; they are a functional necessity for the modern network engineer. By turning raw data into visual information, you minimize downtime and maximize your efficiency across the CLI. regex patterns to copy-paste into your Cisco highlight set?
