# 26.4 - April 2026

### Summary

In **26.4** we've added the ability to discover all ports on complex switches and set an agent on each Controller. 

### Complex switch port discovery - Beta

Highlight can now discover all ports on complex switches with indices such as 1/1/1. This is currently available in Beta for Cisco 92XX, 93XX and 95XX switches.  Other manufacturers and models are being tested before the change is expected to be widely available.

[Contact us](/getting-started/contact-us.md) to enable this functionality.

Highlight can now discover ports with an index such as 1/1/1.  

Indices with four components are restricted for now.  
{% endhint %}

### Set an agent on each controller 

Setting an agent on controller discovered watches was previously a folder setting.  This can now be changed on the **Settings** tab on a controller and applies to all watches associated with that controller. This change makes it possible to spread the load across multiple agents.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.highlight.net/getting-started/release-notes/26.4-april-2026.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
