Managing CME using a Graphic User Interface (GUI) offers a number of advantages, some
of which can be seen on the surface, whereas others might not be as evident. First, many
small offices use an all-in-one administrator whose knowledge is spread across many dif-
ferent technologies. To force this level of administrator to learn a complete command-line
operating system to interact with CME is unrealistic. Similarly, some offices use consult-
ants or contract network administrators to manage their network. Providing an easy-to-use
GUI allows one of the more technically inclined users at the office to take care of the day-
to-day administration (changing directory numbers, adding phones, and so on) without
the involvement of dedicated IT staff. Finally, the point-and-click of a graphic interface
can be more efficient at times than typing configuration commands.
Although Cisco has released multiple GUI management tools to configure CME over the
years, two primary tools are used today: the integrated CME GUI and Cisco Configura-
tion Professional (CCP). The integrated CME GUI is powered by HTML and JAR (Java)
files loaded into the flash of the CME router. Typically, the CME router ships with these
files preloaded by Cisco into the flash; however, you can also download a TAR package of
files from the Cisco website (assuming you have a valid support contract) and extract the
files into the flash of the router. With minimal command-line configuration (assigning an
IP address and enabling the HTTP server), you can have the integrated CME GUI up and
running in no time, as shown in Figure 4-1.
Although the integrated CME GUI is not “pretty” by today's standards, it is functional,
which enables you to handle most core functions of CME: adding/changing phone config-
urations, modifying the dial-plan, configuring hunt groups, and so on. Keep in mind that
this, too, runs from the flash of the CME router, so conserving space is more important in
Cisco's mind than adding “gloss” to the utility.
Cisco focused the integrated CME GUI on configuring only the telephony aspects of the
CME router. It created the CCP to configure
all
major aspects of the CME router. It en-
ables simple (and often wizard-based) configuration of the router, firewall, Intrusion Pre-
vention System (IPS), Virtual Private Network (VPN), Unified Communications, and
common WAN and LAN features and configurations. You can download the latest version
of the CCP software from the Cisco website free of charge. CCP is roughly a 200 MB in-
stallation on a local PC. After you install it on your local PC, you can manage any sup-
ported Cisco platform using the utility. (You do not need to install anything on the
managed devices.)
