Initializing and Registering Your ACNS Network Devices

The Cisco CE can run in four different modes, corresponding to the ACNS elements you learned about previously: CDM, CE, CR, and IP/TV Program Manager. These four modes are available as separate personalities within the same ACNS operating system. To change the device mode, you simply need to enable the mode and reboot the CE for the changes to take effect. The CE command to change the mode of a CE is

 device mode {content-router | content-engine | content-distribution-manager |   program-manager} 

The following series of CEs is available for enabling the three ACNS device modes:

  • Content Engine Network Modules CE network modules for the Cisco 2600 and 3600 series multiservice platforms and the Cisco 2800 and 3800 series integrated services routers. You can enable these service modules as CEs only.

  • Content Engine 511 series The CE 511 is an entry-level platform for small branch offices. Like the CE network module, you can enable these devices as CEs only.

  • Content Engine 566 and 7326 series These are higher-end series CEs, with faster CPUs and more storage capacity than the CE 511. These series CEs can support the CDM, CE, CR ACNS device modes.

If you are configuring your device for the first time, you should allocate disk space appropriately for the following disk regions on your ACNS devices:

  • System File System (sysfs) Allocated for system use.

  • Cache File System (cfs) Allocated for caching unmanaged HTTP and FTP objects on standalone CEs, which you learned about in Chapter 13. Unmanaged objects are sourced from public Internet origin servers.

  • Media File System (mediafs) Allocated for unmanaged VoD proxy caching, using the WMT proxy or RealProxy, that you also learned about in Chapter 13.

  • Content Delivery Network File System (cdnfs) Allocated for pre-positioning managed content, which you centrally administer with a CDM. Managed content is content that you source from an origin server that you manage yourself (for example, an intranet web or FTP server or an enterprise WMS server).

To allocate the percentage of disk space for each region, use the command

 disk config sysfs sys-percent cfs cache-percent mediafs stream-percent cdnfs  cdn-percentage 

For example, for CEs primarily used for prepositioned content, you can weight the allocation more toward the cdnfs, as follows:

 disk config sysfs 10% cfs 15% mediafs 15% cdnfs 60%

As mentioned previously, you must configure and enable your ACNS devices from the CDM GUI. For devices to be configurable on the CDM, you must first register them using DHCP or with the CE command

 cdm ip { ip-address | hostname} 

For more information on registering your CEs using DHCP, refer to your product documentation.

To enable the ACNS process on your device, which will enable you to configure your device with the CDM, enter the following command:

 cms enable

This command enables a management database that contains the device configuration you create and modify using the CDM. Without this command, you cannot manage the device with the CDM.
