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:
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:
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. |
