Collect Expressway/VCS Diagnostic Log for Expressway MRA

Introduction

This document describes how to enable specific debug logs when you troubleshoot non-Single Sign-On (SSO) and SSO-enabled Jabber and non-Jabber Mobile and Remote Access (MRA) via Expressway/Video Control Server (VCS).

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

• Have installed Expressway-Core/VCS-Control and Expressway-Edge/VCS-Edge
• Have applied the appropriate release and option keys on the Expressway/VCS Core and Expressway/VCS Edge
• Have configured Expressway MRA
• Have access to the Expressway/VCS Core and Expressway/VCS Edge with an administrator account by the web interface 

Note: Navigate to the Expressway MRA deployment guides for more information.

Components Used

The information in this document is based on these software versions:

• Expressway/VCS version X8.10.4
• Expressway/VCS version X8.X releases

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, ensure that you understand the potential impact of any command.

Note: The words, Expressway and VCS, are interchangeable. From this point on, Expressway is used.

Background Information

The non-Jabber devices are the 78XX/88XX IP phones and DX Series endpoints. With regards to the problems with Jabber and non-Jabber MRA via Expressway/VCS, you can enable debug logs on the Expressway/VCS servers, reproduce the problem, and upload the logs to the case which expedites the troubleshooting process, and ultimately, the case resolution. These problems include, but not limited to, Jabber MRA login failure, specific Jabber service(s) that fails to register, no-way or one-way audio, etc.

For non-SSO and SSO-enabled MRA via Expressway, provide these details for the affected user's:

• Username
• Device name
• Timestamp of the login
• Timestamp of the error received
• The error message received

For no-way audio or one-way audio MRA calls via Expressway, provide these information:

• Calling party device name and extension
• Called party device name and extension
• Call flow
• The direction of the audio failure, e.g., one-way or no-way
• Timestamp of the call placed

Note: If the Expressway-Core and Expressway-Edge servers are clustered, e.g., more than one Expressway-Core and Expressway-Edge servers, perform the log capture only on the master/primary Expressway-Core and Expressway-Edge servers. After the problem is reproduced, you can download the logs from the primary Expressway-Core and Expressway-Edge servers. Then, log into the secondary Expressway-Core and Expressway-Edge servers and download the logs. If you have multiple Expressway-Core and Expressway-Edge servers, repeat this step for the rest of your secondary Expressway-Core and Expressway-Edge servers.

Jabber MRA via Expressway Non-SSO
