Procedure 4: Chassis and Appliance Firmware Support
With the dual boot feature, you can switch between two installed versions of Spirent
TestCenter using the command line interface. You can identify the current version and
standby version using the appropriate commands. This feature is available on SPT-N12U,
SPT-N11U, SPT-N4U, SPT-C50, SPT-C1, and PX3/DX3-QSFP-DD-8.
SPT-N12U, SPT-N11U, and SPT-N4U
For SPT-N12U, SPT-N11U, and SPT-N4U chassis, this feature applies to Spirent
TestCenter releases 4.87 and later. When you initially upgrade to release 4.87 or later, both
installed versions will be 4.87 or later. Subsequent upgrades to releases later than 4.87 will
result in two separate partitions, containing the current version and the standby version,
respectively.
Notes: •
Downgrading to a version below 4.87 removes this feature.
