Table 4-2 Device Activation Fields
Field Description
Name Name of the device.
Activate To activate or deactivate the device, check or uncheck the Activate check box.
Server Offload To offload this device for maintenance or a software upgrade, check the Server
Offload check box. When checked, the Service Router stops sending requests to
this device.
Note If a client paused a program at that moment Server Offload is enabled,
most likely resuming the program will fail.
To monitor the current streams on an SE during the Server Offload state, use the
show interface command. If the packets received or packets sent is increasing then
the SE is streaming. Packets received will be high if there is an incoming stream.
Note We recommend separating the management traffic from the streaming
traffic by using the port channel configuration, see the “Configuring Port
Channel” section on page E-1 for more information.
1. If management and streaming traffic are separated, the show interface
command for the streaming port channel displays information on active
sessions.
2. If management and streaming traffic are not separated, the show interface
command shows very low traffic; the packets received and packets sent are
lower than a client streaming session.
Once the SE has finished streaming, you can perform maintenance or upgrade the
software on the device. For information about upgrading the software, see the
“Upgrading the Software” section on page 8-6.
The Status field on the Device Activation page and the Devices Table page displays
“offloading” when Server Offload is checked.
Once the software upgrade or maintenance is complete, you need to uncheck the
Server Offload check box so that the device can again participate in the system.
Note If the Server Offload option is set on an SE that is acting as the Content
Acquirer for a delivery service for dynamic ingest or live stream splitting,
a new SE is chosen as the Location Leader for the delivery service.
However, if the Content Acquirer is up and communicating with the
CDSM, it continues to perform content ingest and content distribution.
Content Cache Informational only. The content cache size is the total disk space on the CDS
network file system (CDNFS) on the SE that is designated for cache. The Content
Cache represents the unused cache space. The used cache space is the disk space
allotted for all the delivery services to which the SE is assigned. To view the used
cache space, choose Services > Service Definition > Delivery Services > Assign
Service Engines.
