You should already have a working CUCM install within a virtual machine with a supporting network and services, as described in lab A-1. This is the same setup you've been using in all of your chapter 8 and 9 labs. If CUCM and your web browser aren't already running, start them—detailed instructions are contained in the first several steps of 8-1.
Concepts
We'll concern ourselves with two kinds of services in this lab.
Network services are activated as part of the CUCM installation process and begin running when CUCM starts. You can stop or restart them, but that's it; you can't deactivate them.
Feature services, like TFTP and even the CallManager service, are not activated as part of the CUCM installation process; they need to be manually activated by an administrator. This approach helps keep your hardware running fast and cool by only running the features that you need and are licensed for.
The Feature Services Status page, shown in the third screenshot of the walkthrough below, lists two kinds of status:
Status—Whether a service happens to be running at the moment or not
Activation Status—Activated services are those that start when CUCM starts. They might be manually stopped or restarted while CUCM is running, but they're still considered an activated part of the CUCM system. Each time CUCM starts, all activated services are started, regardless of whether they happen to have been stopped when CUCM was last shut down.
Tasks
View the list of running network services and restart one for fun. (You are in a lab environment with no real users, aren't you?)
Go to the feature services activation page. Turn on "Cisco CallManager" and "Cisco TFTP"
Go to the feature services control center and observe that while you can stop or restart activated services there, you can't actually activate or deactivate them.

Exam Objectives
This is never explicitly mentioned in Cisco's exam objectives, but it is fundamental to much of your ability to make CUCM useful, for example by adding phones, which we'll start doing in our next lab. For troubleshooting purposes, you might also keep in mind the consequences of not activating various feature services.
Lab Walkthrough (Screenshots are clickable)
In your web browser, navigate to the Cisco Unified Serviceability page (https://10.0.4.5/ccmservice). If you're already in the system, say on the CM Admin page, you can switch to the Serviceability page using the navigation drop-down in the upper-right-hand corner of the page. Log in if you need to (student/ciscoclass), but you knew that.
View / Restart Network Services
Open the Network Services Control Center.
(Serviceability) Tools → Control Center - Network Services
The status column shows that all network services are already running, but if you select one, you can stop or restart it, using either the buttons at the bottom of the screen or the icons near the top. The circles in the left column are radio buttons, allowing you to stop/restart only one service at a time. Pick a service and restart it.
Activate Feature Services
Open the Service Activation window. You can either use the menu sequence below or the "Related Links" drop-down at the right end of the black bar directly below the menus. This is the same black bar that holds the title of the current page.
(Serviceability) Tools → Service Activation
On this page, the left column has square checkboxes instead of radio buttons, allowing you to activate / deactivate more than one of the listed services at a time. In the "CM Services" section, check the boxes next to "Cisco CallManager" and "Cisco Tftp" and click the [Save] button at the bottom of the list or the "Save" icon at the top to activate them. After a refresh, those services will show an activation status of "Activated." Activating a feature service will also automatically start it. Activated services automatically start when CUCM does.
View the Status of Feature Services
Open the Feature Services Control Center, either through the related links drop-down, or explicitly:
(Serviceability) Tools → Control Center - Feature Services
If an activated feature service were to fail to start after being activated, this is where you would manually start it.
You Can't Activate Features Here
If you click the radio button next to a deactivated (never activated) service, a popup will tell you to go to the Service Activation screen instead. This is the same screen you were just on when you activated "Cisco CallManager" and TFTP.
So just like with the Network Services Control Center, you can't activate/deactivate from here, but you can stop and restart feature services. Try stopping the TFTP service. After the page (eventually) refreshes, you'll see that the service has a status of "Not Running," but still has an activation status of "Activated." If you're going to continue working on labs, you'd better start the TFTP service back up. If you're shutting down CUCM for the day, don't bother; all activated services will automatically start when CUCM is restarted regardless of whether they were running when CUCM was shut down.
