Logging in to Standalone Content Engines
The term standalone Content Engines is used throughout this guide to refer to Content Engines that ACNS administrators have intentionally not registered with the Content Distribution Manager so that they can configure, manage, and monitor these Content Engines as standalone devices. Multiple standalone Content Engines can be deployed (for example, you can deploy clusters of standalone Content Engines).
After you have done a basic configuration on a standalone Content Engine, you can perform other basic tasks such as the setting the system clock, managing login accounts, and managing and monitoring disks. For more information on this topic, see Chapter 5, "Performing Other Basic Tasks for Standalone Content Engines."
Note
For complete syntax and usage information for the CLI commands used in this chapter, see the Cisco ACNS Software Command Reference, Release 5.5 publication. For information about how to configure Content Engines that are registered with a Content Distribution Manager, see the Cisco ACNS Software Configuration Guide for Centrally Managed Deployments, Release 5.5.

Configuring a Basic Configuration on Standalone Content Engines with the Setup Utility
This section provides an overview of the Setup utility and describes how to use this tool to configure a basic configuration on a standalone Content Engine in either of the situations:
•
Case 1—The Content Engine is being booted up for the first time (for example, the Content Engine was purchased with the ACNS 5.4 software), and you want to use the Setup utility to configure the basic configuration settings (the general settings [device network settings and disk configuration], and a set of commonly used caching services [listed in Table 4-2]).
•
Case 2—The device is a standalone Content Engine with some basic configuration (for example, the Content Engine was upgraded to the ACNS 5.4 software, and already has device network settings, disk configuration, and HTTP proxy caching configured). You want to use the Setup utility to complete the basic configuration of this standalone Content Engine (for example, configure some of the other commonly used caching services that are not yet configured).
In Case 1, the Setup utility is automatically launched when you initially boot up a device. Completing the initial basic configuration in this situation involves these tasks:
•
Deciding the Addressing Scheme for Standalone Content Engines
•
Using the Setup Utility to Configure a Basic Configuration on a Standalone Content Engine
In Case 2, you manually launch the Setup utility with the setup privileged EXEC command. For more information on this topic, see the "Manually Launching the Setup Utility" section.
After completing this basic configuration, you must configure the client browsers and media players (see "Configuring Client Browsers and Media Players for Direct Proxy Routing") for direct proxy routing, and configure the WCCP routers for transparent redirection (see "Configuring WCCP Routers for Transparent Redirection"). After verifying that this basic configuration is working properly, you can use the CLI commands or Content Engine GUI to configure additional caching services (for example, DNS caching, FTP caching, and HTTPS caching), streaming services (WMT streaming and RTSP streaming), or content services. You can also perform advanced configuration or monitor this Content Engine.
Note
Throughout the rest of this chapter the term WCCP Version 2-enabled router denotes a router that is running WCCP Version 2.
Commonly Used Caching Services Configurable Through the Setup Utility
Table 4-2 lists the commonly used caching services that you can quickly configure on a standalone Content Engine through the Setup utility.
Table 4-2 Commonly Used Caching Services Configurable Through the Setup Utility
Caching Service
|
Description
|
HTTP forward proxy caching
|
The standalone Content Engine functions as a nontransparent forward proxy server for HTTP requests. After receiving an HTTP request directly from a client browser, the Content Engine retrieves and caches the requested content if it is not already stored in its local cache, and sends the requested content to the requester (client browser).
|
HTTP transparent caching
|
The standalone Content Engine functions as a transparent proxy server for HTTP requests. After receiving a redirected HTTP request, the Content Engine retrieves and caches the requested content if it is not already stored in its local cache, and sends the requested content to the requester (client browser). With the Setup utility, you can configure the Content Engine to accept redirected HTTP requests from a WCCP Version 2-enabled router. With the Content Engine CLI, you can configure the Content Engine to accept redirected HTTP requests from the WCCP Version 2-enabled router or a Layer 4 switch.
|
HTTP reverse proxy caching
|
The standalone Content Engine functions as a transparent proxy server for specific web servers (for example, web servers in a web server farm) as opposed to acting as a proxy for end users (web clients). After receiving a redirected reverse proxy request, the Content Engine retrieves and caches the requested content if it is not already stored in its local cache, and sends the requested content to the requester (client browser). With the Setup utility, you can configure the Content Engine to accept redirected reverse proxy requests from a WCCP Version 2-enabled router. With the Content Engine CLI, you can configure the Content Engine to accept redirected reverse proxy requests from a WCCP Version 2-enabled router or a Layer 4 switch.
|
WMT proxy caching
|
The standalone Content Engine functions as a nontransparent proxy server for end users who are using Windows Media Player to request WMT content. After receiving a WMT request directly from a client Windows Media Player, the Content Engine retrieves the requested content if it is not already stored in its local cache, stores a copy locally whenever possible, and sends the requested content to the requester (client Windows Media player).
|
WMT transparent caching
|
The standalone Content Engine functions as a transparent proxy server for end users who are using Windows Media player to request content. After receiving a transparently redirected WMT request, the Content Engine retrieves the requested content if it is not already stored in its local cache, stores a copy locally whenever possible, and sends the requested content to the requester (client Windows Media player). With the Setup utility, you can configure the Content Engine to accept redirected WMT requests from a WCCP Version 2-enabled router. With the Content Engine CLI, you can configure the Content Engine to accept redirected WMT requests from a WCCP Version 2-enabled router or a Layer 4 switch.
|
RealMedia proxy caching
|
The standalone Content Engine functions as a nontransparent proxy server for end users who are using a RealMedia player to request RTSP content. After receiving an RTSP request directly from a RealMedia player (for example, RealPlayer), the Content Engine retrieves the requested content if it is not already stored in its local cache, stores a copy locally whenever possible, and sends the requested content to the requester (the RealMedia player).
|
RealMedia transparent caching
|
The standalone Content Engine functions as a transparent proxy server for end users who are using a RealMedia player to request content. After receiving a redirected RTSP request, the Content Engine retrieves requested content, stores a copy locally whenever possible, and sends requested content to the requester (the RealMedia player). With the Setup utility, you can configure the Content Engine to accept redirected RTSP requests from a WCCP Version 2-enabled router. With the Content Engine CLI, you can configure the Content Engine to accept redirected RTSP requests from a WCCP Version 2-enabled router or a Layer 4 switch.
|
Using the Setup Utility
The following are some important points when using the Setup utility:
•
When the Setup utility is invoked on a Content Engine that supports device mode changes (for example, the CE-565 or the CE-7306), you are prompted to specify the device mode for that particular device. When prompted, press Enter or enter CE to specify the Content Engine device mode for this standalone Content Engine.
What is the mode of the device (CE/CR/CDM/PM) [CE]: CE
When prompted, enter no to specify that this Content Engine is not going to be managed by a Content Distribution Manager.
Is this CE going to be managed by a CDM (Content Distribution Manager)
(y/n) [y]: no
•
When a series of basic configuration questions appears, press Enter or enter y to indicate that you want to configure a particular caching service on this standalone Content Engine. (See Table 4-2 for a description of these services).
•
After you respond to the series of basic configuration questions, a menu-based interface appears.
+-----------------------------------------------------+
+-----------------------------------------------------¦
¦ -General Settings :Incomplete ¦
¦ Caching Related Configurations :Incomplete ¦
+-----------------------------------------------------+
Configure network settings, disks, etc
Press '?' to see why this item is incomplete
For a list of the Setup utility menu options, see Table 4-3.
•
When you are prompted for a particular configuration setting, the default value is displayed. Press Enter to select the default value. For example, press Enter to specify that you want to use the default WCCP router (default gateway that has the IP address of 10.0.1.1) when prompted as follows:
Please enter the IP addresses of WCCP routers [10.0.1.1]:
•
After you specify whether you want to configure a particular setting, the corresponding menu option is marked as "Complete" or "Incomplete." This helps you track which basic configuration settings you have configured and which ones still need to be configured on this standalone Content Engine.
•
When you configure a particular setting by choosing a menu option in the Setup utility, the corresponding CLI command is configured. (See Table 4-3.) After you use the Setup utility to specify a specific basic configuration setting, a list of configured CLI commands appears (see example). When you are asked if you want to save this configuration, press Enter to save the displayed configuration.
NOTE: Please remember to configure web-cache service on the router.
Based on the input, the following CLIs will be configured:
wccp router-list 1 10.0.1.1
wccp web-cache router-list 1
Do you accept these configs (y/n) [y]:
•
To display a list of constructed CLI commands at any time during a Setup utility session, choose the Print Configurations option from the Setup utility menu.
•
After you specify a configuration setting, the Setup utility reports any dependencies or incompatibility between the specified options. For example, if you have enabled any of the streaming caching services, then you are informed that you should allocate disk space for the media file system (mediafs) when you configure the disk.
•
If any failure occurs when the Setup utility is applying the specified configuration settings (for example, the disk configurations and the corresponding CLI command), the Setup utility displays a message indicating which specific setting could not be applied. Error messages are also written to /local1/errorlog/setup_(clildisk)_config_error.
•
A basic configuration (see example) is constructed based on the information that you specify through the Setup utility. The following is an example of a basic configuration for a standalone Content Engine that has all seven of the commonly used caching services configured:
Here is the current profile of this device
HTTP Tranparent Caching : Yes
HTTP Reverse Proxy Caching : Yes
WMT Transparent Caching : Yes
Real Media Proxy Caching : Yes
Real Media Transparent Caching: Yes
Do you want to change this (y/n) [n]:
Press the ESC key at any time to quit this session
This basic configuration is cached. A copy of the configurations generated through the Setup utility is stored on disk (/local/local1/setup_gen_config.txt).
•
For information about how to launch the Setup utility, see the "Launching the Setup Utility" section.
Setup Utility Menu Options and Corresponding CLI Commands
The menu structure of the Setup utility is hierarchical. For example, after you choose the General Settings option from the main menu, the General Settings submenu appears. As the following example shows, your current location in the menu structure is displayed after the menu options.

Deciding the Addressing Scheme for Standalone Content Engines
Before beginning the initial configuration of a Content Engine as a standalone device, you should decide which addressing scheme will be used for this Content Engine. The two supported addressing schemes for standalone Content Engines that are running the ACNS 5.x software are mutually exclusive:
•
Manually specify a static IP address and network mask.
•
Dynamically assign an IP address using the interface-level DHCP addressing scheme.
Note
Autoregistration needs to be disabled on the Content Engine before you can configure a Content Engine interface with interface-level DHCP or a static IP address. For information about how to disable autoregistration through the Setup utility, see Step 1 in the "Using the Setup Utility to Configure a Basic Configuration on a Standalone Content Engine" section.
If you do not enable interface-level DHCP on the Content Engine, you must manually specify a static IP address and network mask for the Content Engine. If the Content Engine moves to another location in another part of the network, you must manually enter a new static IP address and network mask for this Content Engine.
If you want to enable DHCP and are using the Setup utility to configure a standalone Content Engine, answer y when prompted (as described in Step 7 in the "Using the Setup Utility to Configure a Basic Configuration on a Standalone Content Engine" section).
Do you want to enable DHCP on this interface? (y/n) [y]:y
If you are using the CLI method (instead of the Setup utility) to configure a standalone Content Engine, use the ip address dhcp interface configuration to enable interface-level DHCP on a standalone Content Engine.
About Device Network Settings for Standalone Content Engines
In order to deploy a device as a standalone Content Engine on your network, you must initially configure a set of network settings on the Content Engine. These settings are collectively referred to as device network settings. After the device network settings are defined for the standalone Content Engine, it can become active on your network.
The device network settings that you should have before you start the basic configuration include the following:
•
Host name of the Content Engine (for example, if you assign the Content Engine the name CE7305, the prompt will appear as:
•
Internet Protocol (IP) domain name (for example, cisco.com)
•
Administrator password
•
IP addresses for the Content Engine
If a static IP address is assigned to this Content Engine (for example, 10.0.1.2 as shown in Figure 4-4,) then you must also assign it an IP address network mask (for example, 255.255.255.0).
Tip
You also have the option of using interface-level DHCP to dynamically assign an IP address to a Content Engine interface instead of manually assigning a static IP address and network mask.
•
Default gateway (for example, the router with address 10.0.1.1 is the default gateway for the Content Engine shown in Figure 4-4)
•
DNS name server (for example, in Figure 4-4, the Content Engine will use the DNS server with the address 172.16.0.2 for domain name resolution)
Figure 4-4 Configuring Device Network Settings on Standalone Content Engines
.
Note
Throughout the rest of this chapter, the term general settings is used to refer collectively to device network settings and disk configuration.
The ACNS 5.x software provides a Common Interface File System (CIFS) client and a Network File System (NFS) client for Content Engines to communicate with network attached storage (NAS) devices. For more information on this topic, see the "Mounting to a Network Attached Storage Device" section on page 5-13.
Using the CLI Command Method to Configure General Settings for Standalone Content Engines
To use the CLI command method (instead of the Setup utility) to configure the general settings on a standalone Content Engine, follow these steps:
Step 1
Open a console connection on the Content Engine, and log in to the Content Engine CLI using an ACNS system account that has superuser privileges. For more information see the "Using Telnet or a Console Session to Log in to a Standalone Content Engine" section.
Step 2
From privileged EXEC mode, enter global configuration mode to specify the general settings for this standalone Content Engine:
Step 3
Configure the Ethernet interface on this Content Engine. You must do one of the following:
•
To assign a static IP address and network mask (and not enable DHCP on this interface), enter the following command:
CE(config)# interface {FastEthernet | GigabitEthernet} slot/port
ip address ip-address netmask
•
To enable interface-level DHCP, enter the following command:
CE(config)# interface {FastEthernet | GigabitEthernet}
slot/port ip address dhcp
If you configure your Ethernet interface using interface-level DHCP, then the remainder of the device network settings for this standalone Content Engine are automatically configured and you are finished with the configuration of the device network settings. If you manually assigned a static IP address, use the ip default-gateway, ip name-server, hostname, ip domain-name, and primary-interface global configuration commands to specify the remaining device network settings. Use the disk config sysfs global configuration command to use the Content Engine CLI command method to configure disk space.
Launching the Setup Utility
The Setup utility can be launched in these ways:
•
Manually at any time by entering the setup privileged EXEC command at the CLI prompt
•
Automatically when you initially boot up a device
Note
A Content Engine that is running the ACNS software comes with a single predefined superuser user account (root administrator). This predefined account can be used to invoke the Setup utility. The username for this predefined superuser user account is admin and the default password is default. If these defaults have been changed by another ACNS system administrator, you must obtain the new username and password.
Manually Launching the Setup Utility
To launch the Setup utility manually on a standalone Content Engine that already has its device network settings defined, follow these steps:
Step 1
Using a login account that has the superuser privilege rights (privilege level of 15), log in to the Content Engine CLI through Telnet or Secure Shell (SSH) Version 1 or Version 2.
Note
For more information about logging in to the Content Engine CLI, see the "Using Telnet or a Console Session to Log in to a Standalone Content Engine" section. For more information about the different CLI modes, see the "ACNS Software CLI Command Modes for Standalone Content Engines" section on page B-8.
Step 2
Launch the Setup utility manually to configure one or more of the commonly used caching services (listed in Table 4-2).
The current basic configuration for this standalone Content Engine appears.
The displayed basic configuration also indicates which of the commonly used caching services are already configured on this Content Engine. In this case, only the HTTP proxy caching service is currently configured on this Content Engine.
Here is the current profile of this device
HTTP Tranparent Caching : No
HTTP Reverse Proxy Caching : No
WMT Transparent Caching : No
Real Media Proxy Caching : No
Real Media Transparent Caching: No
Note
The displayed basic configuration indicates that this Content Engine is not a CDN device. This is because the standalone Content Engine is intentionally not registered with a Content Distribution Manager.
You can quickly modify the basic configuration of this standalone Content Engine by entering y when prompted as shown below.
Do you want to change this (y/n) [n]:y
For more information about how you can use the Setup utility to configure or modify the basic configuration of this Content Engine, see the "Using the Setup Utility to Configure a Basic Configuration on a Standalone Content Engine" section.
Automatically Launching the Setup Utility
When you initially boot up a device, follow these steps to launch the Setup utility automatically:
Step 1
Power up the Content Engine and open a console connection.
You must use a console connection rather than a Telnet session for initial configuration of these device network settings on the Content Engine. However, once you have used a console connection to define the device network settings, you can then use a Telnet session to perform subsequent configuration tasks on this Content Engine. For more information about using a console connection, see the "Using Telnet or a Console Session to Log in to a Standalone Content Engine" section.
After the operating system boots up, the following prompt appears:
ACNS boot:detected no saved system configuration
Do you want to enter basic configuration now?
hit RETURN to enter basic configuration:0019
At the appearance of this prompt, a 30-second countdown begins, during which you can launch the Setup utility.
Step 2
Press Enter.
Step 3
When prompted, enter the administrator password and press Enter.
This is the case-sensitive password for the predefined superuser account. The password can include any printable character. By default, the username is admin and the password is default. The administrator password can be up to 20 characters long and is case sensitive. Each Content Engine in a farm must have a password. You must enter a password before pressing Enter.
Step 4
When prompted, reenter the administrator password and press Enter.
The Setup utility is automatically launched, and you are prompted to specify the device mode for this particular device. When the Setup utility is launched on a Content Engine that supports device mode changes (for example, the CE-565), you are prompted to specify the device mode for that particular device.
Step 5
When prompted, press Enter or enter CE to specify the Content Engine device mode for this standalone Content Engine.
What is the mode of the device (CE/CR/CDM/PM) [CE]: CE
Step 6
When prompted, enter no to specify that this Content Engine is not going to be managed by a Content Distribution Manager.
Is this CE going to be managed by a CDM (Content Distribution Manager)
(y/n) [y]: no
For more information about how to use the Setup utility after booting up a device for the first time, see the "Using the Setup Utility to Configure a Basic Configuration on a Standalone Content Engine" section.
Using the Setup Utility to Configure a Basic Configuration on a Standalone Content Engine
To use the Setup utility to configure a basic configuration on a standalone Content Engine, follow these steps:
Step 1
Launch the Setup utility.
•
If this is the first time that the device is being booted up, follow these steps:
–
Power up the device, open a console connection, and automatically invoke the Setup utility. (For detailed instructions, see the "Automatically Launching the Setup Utility" section.)
–
When the Setup utility is launched on a Content Engine that supports device mode changes (for example, the CE-565), you are prompted to specify the device mode for that particular device. When prompted, press Enter or enter CE to specify the Content Engine device mode for this standalone Content Engine.
What is the mode of the device (CE/CR/CDM/PM) [CE]: CE
–
When prompted, enter n to specify that this Content Engine is not going to be managed by a Content Distribution Manager.

(y/n) [y]:n
By default, the autoregistration is enabled on a Content Engine. When autoregistration is enabled on a Content Engine, the Content Engine automatically searches for and register with the Content Distribution Manager on the network. Because you want to deploy your Content Engine as a standalone device that is not registered with a Content Distribution Manager, you must specify n to disable autoregistration on this Content Engine.
Note
If you are using the CLI method to configure a standalone Content Engine (instead of the Setup utility), you can manually disable autoregistration by specifying the no auto-register enable global configuration command.
–
Proceed to Step 2 below.
