TRex 9 / 113
Note
• Requirement for using TRex: sudo or root password for the machine.
• Upgrading the linux Kernel using yum upgrade requires building the TRex drivers.
• In Ubuntu 16, auto-updater is enabled by default. It is recommended to turn it off. Updating kernel requires re-compiling the
DPDK .ko file.
To disable auto-updater:
> sudo apt-get remove unattended-upgrades
