Course Overview
(Music) Hi, everyone. I'm Sean Douglas, and I want to welcome you to my course, Troubleshooting User, Gateway, and Endpoint Registrations Issues. I've been a Cisco engineer and instructor for nearly two decades, and in that time I've taught thousands of adults a lot about Cisco. This course, which is part of an ongoing series, is designed to make sure that you understand exactly how to diagnose problems, so that when end users tell you, it won't let me, or the mysterious, it's not working, you'll be prepared to precisely identify the exact issue and come up with the solution. You may end up being the most popular person on the team. Your coworkers might say, hey, go to so-and-so with those issues, they took those Pluralsight course and they always know how to fix it, because we're going to give you real-world solutions. We're going to show you how to troubleshoot Cisco collaboration deployments and we'll do it in a way that's easy to understand. We're going to use extensive demonstrations, hands-on, step-by-step configuration examples so that by the end of this course, you'll be able to identify problems, gather facts, create an action plan, and solve the issue. We've designed this course to have extensive hands-on examples so that you'll be able to reference our step-by-step demonstrations in your day-to-day career. Before beginning this course, you should have a solid understanding of Cisco Unified Communications Manager, either by having watched the previous courses, Building a Cisco SIP URI-based Dial Plan with ILS, SME, and Unified Mobility; Building a Cisco VCS Controlled Dial Plan and Expressway Remote Access Solution; Building Gateways, SIP Trunks, and Cubes for Cisco Collaboration; or by being at about the CCNA collaboration level or having some experience working with Cisco Unified Communications Manager. I hope you'll join us as we build solutions with the Troubleshooting User, Gateway, and Endpoint Registration Issues course here at Pluralsight.

Troubleshooting MGCP Gateway Registration Issues
MGCP, Media Gateway Control Protocol, is supposed to make gateway management life a lot easier for collaboration administrators. When it's configured properly and the gateway registers to Unified Communications Manager, yes, alright, it's smooth sailing, but getting it there, getting the bumps ironed out and making sure that the gateway and Unified Communications Manager are actually working and in sync, well, that can be kind of tricky and that's why we're here. Hi everyone. My name is Sean Douglas and I want to welcome you to the module, MGCP Gateway Registration Issues. In this module, we're going to go through the step-by-step process of getting an MGCP gateway created and registered to Unified Communications Manager. Once it's up and running and working, then we're going to demonstrate a series of show and debug commands that we can use to pull information and troubleshoot, diagnose problems when they're occurring. I'm going to show you how to save time, avoid headaches, and get back to what's really important, making phone calls. Our goals for this module are going to be to demonstrate solutions to MGCP registration issues. When MGCP is registered and it's working fine, it's great. You can configure the entire dial plan from Unified Communications Manager, but there's always a monkey in the wrench, a fly in the ointment, and in this module, we're going to show you how to find it, get it out of there, and get back to business. We're going to demonstrate configuring an MGCP gateway at our South location; we're going to build it from scratch. Then we're going to demonstrate how to troubleshoot MGCP registration. We're going to create a scenarios of scenarios where the MGCP gateway is just not working correctly. It's not registered. It's not doing its job. Then we're going to use a variety of show, and especially MGCP debug commands so that we can gather information, get the facts, and get the show back on the road.

Troubleshooting LDAP Synchronization and Authentication Issues
As collaboration administrators, you guys know that the amount of things that we've got to keep straight and organized; users, gateways, trunks, protocols; it can all seem overwhelming, and because of that, I'm always looking to simplify and find more efficient ways of dealing with routine tasks, like creating end users and managing their passwords. Fortunately, we can use LDAP for that; Lightweight Directory Access Protocol allows us to store our users and their passwords in one place, on a Microsoft Active Directory server. Then all we've got to do is set up Unified Communications Manager to pull that information in. What could be simpler? Well, it works great, it's secure, and it's efficient when it works. When it doesn't, well, if you're like me, that's just frustrating. Hi everyone. I'm Sean Douglas and welcome to the module, Troubleshooting LDAP Synchronization and Authentication Issues. In this module, we're going to demonstrate how to diagnose and correct Microsoft Active Directory integration issues. Our goals for this module are going to be to demonstrate troubleshooting and then finding solutions for LDAP deployments. We're going to demonstrate how to troubleshoot LDAP synchronization. This is where we have the user in the Microsoft server and then we can pull that user in and synchronize it to Unified Communications Manager. Once it's there, that user can then be used in other deployments like Jabber, Unity Connection, so we can have one user created in a single place, the Microsoft database, the Active Directory server, and then have that user propagated and deployed throughout the enterprise. Then we're going to demonstrate how to troubleshoot LDAP authentication. Once we've got synchronization working, we have the option of turning on LDAP authentication. This allows us to have a single password created, managed, maintained in the Microsoft database, and then that password can be used by our user account whenever they sign into Unified Communications Manager, Cisco Unity Connection, Jabber clients; a variety of different applications can use that password once we've got it configured and it's all working.

Troubleshooting TelePresence VCS SIP Endpoints Registration Issues
Hi everyone. I'm Sean Douglas, and welcome to the module, Troubleshooting TelePresence VCS SIP Endpoint Registration Issues. In this module, we're going to troubleshoot registering our SIP endpoint, which is a third-party SIP phone video device with Cisco VCS control, but it's actually a lot more than that. There's a lot of pieces to this puzzle. We've got the VCS control server, but to provision users and devices, we have to enlist a Cisco TelePresence Management Server, TMS, and the users themselves, well, they come from our Microsoft LDAP server. It's an interesting challenge for us. We've got different servers from different vendors speaking different protocols, and that can seem overwhelming, but that's why we're here. Our goal is to take the overwhelming out of overwhelming so that what's left is just, oh hey, you fixed my problem, thanks! We're going to use a variety of free tools, which will allow us to isolate the issue and fix it. Troubleshooting endpoint registration with VCS can get complicated because of all the different servers that are involved, but we're working with SIP and we know that SIP sends requests and responses. So we just need to come up with a way that we can gather those. We're going to demonstrate how we can use the Cisco router's traffic export tool to help us with that, because the traffic, the SIP traffic, the registration SIP traffic, has to pass through the router. So we're going to use this tool, which allows us to capture traffic and then we can examine that using Wireshark. Once we pull it up in Wireshark, then we can read what exactly is being requested and more importantly, what's being responded to. SIP responses are documented, and we can use that documentation to help us troubleshoot. And finally, we're going to demonstrate how we can use VCS logs. All of the traffic that's being generated in the requests and the responses are documented within VCS. Because when it comes to working with SIP, the ability to gather these traces and then read the requests and responses is the key, and in this demonstration, we're going to show you how to do that with any device in your network that's speaking SIP.

Troubleshooting TelePresence Management Server Provisioning Issues
When it comes to deploying SIP endpoints to a Cisco VCS solution, as we saw in the last module, there's a lot of servers involved. In this module, we're going to take a look at one of them, maybe the most important server, the Cisco TelePresence Management Server TMS. This is the server that ties it all together. It allows us to provision users from a Microsoft Active Directory server using LDAP, Lightweight Directory Access Protocol, and it allows to provision endpoints that register to the VCS server. It's the critical component and in order to do its job, it needs to run the provisioning service, but what happens if that doesn't register? In this module, we're going to answer that question. Hi everyone. I'm Sean Douglas, and welcome to the module, Troubleshooting TelePresence Management Server Provisioning Issues. In this module, we're going to demonstrate how to troubleshoot when TMS is given you TMI. The role of the TelePresence Management Server is to give administrators a tool for centralized management, management of endpoints registering to VCS, manage end users being synchronized from Microsoft Active Directory, and manage conference scheduling. In order to do that, the provisioning extension service needs to be activated and operational. In this module, we're going to demonstrate how to troubleshoot when that service just doesn't start. We're going to show you how to use diagnostics and we're also going to demonstrate how to use the TelePresence Management Server's tools. This program runs on the Windows 2008, 2012 server and it has built-in TMS Tools. We're going to demonstrate how to use those tools so that we can get the provisioning service activated and our TMS server back online.
