System Feedback to Cisco TMS Blocked by the Network or Web Server

Introduction

This document describes how to troubleshoot the issue of feedback to Cisco TelePresence Management Suite
(TMS) being blocked by the network or web server.

Prerequisites

Requirements

Cisco recommends that you have knowledge of Cisco TMS.

Components Used

The information in this document is based on Cisco TMS.

The information in this document was created from the devices in a specific lab environment. All of the
devices used in this document started with a cleared (default) configuration. If your network is live, make sure
that you understand the potential impact of any command.

System Feedback to Cisco TMS Blocked by the Network or
Web Server

Cisco TMS relies on feedback sent from systems and verifies the endpoint that connects to it based on serial
number, MAC address, and IP address. Most Cisco TelePresence and third−party systems send this feedback
with anonymous HTTP or HTTPS connections which can be blocked if there is a web proxy on the network
that requires authentication. In this case, you should speak to the administrator of the proxy to add an
exception for traffic destined for Cisco TMS.

Firewalls can also block feedback to Cisco TMS if they block new connections from the system to Cisco
TMS.
