It is important to note that some ApplySets can cause the VBrick appliance to send
unsolicited messages. For example, the appliance may reboot with the following message:
$!Rebooting …
Saving Changes
Once you are done, you must save to persistent storage if you want your edits saved in the
configuration file. Unless you save the configuration, any changes you have made will be lost
if the appliance reboots. A save is always written in the following format with the trailing
=2
.
Note that some changes to the configuration will reboot the VBrick in which case you must
wait for it to reset. Note that you can also use the
SAVE
command as a shortcut.
VBrick> svar vbrickSysSaveConfiguration=2
Error Handling
Programming errors, for example syntax errors, illegal values, etc. display informational
messages in the CLI, for example
$!ERROR=Value out of range
. Other system or network
issues, for example a dropped connection or a failed save (see below) are shown in the System
Log (open VBAdmin and go to Monitor > System Logs > Configuration Log
to see the log).
You can also see all configuration errors using the
ERRORS
command. You can also detect
potential errors in advance by getting the value of various status parameters in the VBrick.
For example, if you are writing a script, you might want to check
Transmitter State
or
FTP
Status
before you set parameters for a related task.
Resetting the Appliance
Use the following command (or the
RESET
shortcut) to reset the appliance. A reset is simply a
reboot. It does not change or reset any configured parameters.
vbrick> svar vbrickSysReset=2
CLI Examples
The following examples show two common configuration tasks. Remember that you only
need to begin an edit session at the start of an edit session or if someone has ended your edit
session. You only need to end an edit session when you are done, and after you have applied
or saved your changes. Also remember that an
ApplySet
command is always required and
comments are not allowed on the same line as a command.
Example 1
This example shows how to read and set the
Target Bit Rate
for the first video rate on
Channel 2. User input commands are shown in bold text.
VBrick# gvar vbrickEncoderVideoH264TargetBitRate.2.1
$!vbrickEncoderVideoH264TargetBitRate.2.1=750000
Then it sets and applies the
Target Bit Rate
to 800K.
VBrick# svar vbrickEncoderVideoH264TargetBitRate.2.1=800000
$!vbrickEncoderVideoH264TargetBitRate=800000
VBrick# svar vbrickEncoderVideoCommonApplySet.1=2
$!vbrickEncoderVideoCommonApplySet=2
