The DEVICE Instance Tag is case sensitive and must be in capital letters. It is used to send Device Services instructions or Device Attributes and Commands.

Device Services

The Following table summarizes DEVICE Service Codes. Due to the nature of the service being requested they do not require specific commands (get, set, etc)

Some service commands are specific to the connected device, such as 'reboot'. Other Service commands are design file specific, such as saving or recalling a Preset.

The TTP string is structured in the following order:

Instance_Tag Service [Value]


Description Service Value
Manual Failover manualFailover unitNumber
Reboot Device you are connected to via SSH or Telnet reboot  
Reset Device you are connected to via SSH or Telnet deleteConfigData  
Reboot Expander class device rebootERD ["hostname", "2nd hostname", "etc"]
Recall a Preset recallPreset Preset ID (Integer)
Recall a Preset and provide device for failures recallPresetShowFailures Preset ID (Integer)
Recall a preset by preset name recallPresetByName Preset name (a string)
Save a Preset savePreset Preset ID (Integer)
Save a preset by preset name savePresetByName Preset name (a string)
Start System Audio startAudio  
Stop System Audio stopAudio  
Start Partition Audio startPartitionAudio Partition ID (integer)
Stop Partition Audio stopPartitionAudio Partition ID (integer)



To reboot the device you are connected to:

Instance Tag Service
DEVICE reboot

Result: DEVICE reboot


To start Audio on a device:

Instance Tag Service
DEVICE startAudio

Result: DEVICE startAudio


To reboot multiple expander devices.

Instance Tag Service
DEVICE rebootERD ["EX-OUT-0000", "EX-IN-0001", EX-AEC-0001]

Result if all expanders are discoverable and accept the reboot command: +OK "failedDevices":[ ]

Result if all but the EX-IN expander are discoverable and accept the reboot command: +OK "failedDevices":["EX-IN-0001"]

Result: DEVICE manualFailover 1


Device Attributes and Commands

Additionally there are a number of DEVICE Instance Tag command Attributes. These would reference the device that has the current active Serial, SSH or TELNET session.


Please refer to the TTP Overview section for more details on the controlling Tesira devices using the TTP protocol.

Each element of the command instruction is delimited by one or more spaces. The commands are case sensitive and upper and lower case characters are used.

The TTP string to adjust a DSP object attribute is structured in the following order:

Host Name hostname get/set   *Host Name modification will not be available unless the device is in an un-configured state. Attempting to modify the Host Name via this command will result in an error message if the system is currently configured. A reset of the device is required to make changes to the Host Name first (DEVICE deleteConfigData command or a Reset Device via Device Maintenance). In the scenario where a system is configured and is Reset to change the Host Name, the Equipment Table will need to be re-opened and updated to reflect the new details, and the configuration re-sent to the system.

ipConfig commands

The ipConfig command can set the DHCP state, IP address, Subnet mask and Gateway on a Tesira Server, Server IO and TesiraFORTÉ device. Only values that need to be changed are required to be specified.


To get the IP configuration of a device:

Instance Tag Command Attribute Code Index
DEVICE get ipConfig control

DEVICE get ipConfig control
+OK "value":{"autoIPEnabled":true "ip":"" "netmask":"" "gateway":""}


To set a device to not use DHCP and with an IP address of, a subnet of and no gateway:

DEVICE set ipConfig control {"autoIPEnabled":false "ip":"" "netmask":"" "gateway":""}


To set a device that is using a fixed IP address to use DHCP

DEVICE set ipConfig control {"autoIPEnabled":true }


To change a device IP address to a new address in the same subnet (this example moves a device from to :

DEVICE set ipConfig control { "ip":"" }
