TLS 1.3 Configuration Overview Guide

TLS 1.3 Configuration Overview Guide

First Published: October 2024

Overview

For security or compliance reasons, administrators can lock down the TLS version of many Cisco Collaboration products to 1.3 and disable TLS 1.0 and TLS 1.1. For an overview, considerations, and implications of enabling TLS 1.3 and disabling TLS 1.0 or 1.1, see the TLS 1.3 for On-Premises Cisco Collaboration Deployments available at Link.

This document provides an overview of how to enable TLS 1.3 and disable TLS 1.0 and 1.1 for Cisco Collaboration products. It also provides references to the relevant product documentation.

Note: Upgrades to 15SU2 or the version mentioned for each product automatically enable TLS 1.3, and only the set TLS version disables versions lower than the configured version.

Configuration

The following table outlines how to configure your Cisco Collaboration products for TLS 1.3.

Prerequisite: Before configuring your products for TLS 1.3, verify that your product versions can enable TLS 1.3 and disable TLS 1.0 and 1.1. For a list of product versions with this capability, see the TLS 1.3 Compatibility Matrix for Cisco Collaboration Products.

Note: You can configure TLS 1.3 and disable TLS 1.0 and 1.1 for the following products in any order.
