Upgrading SLX-OS, TPVM, and EFA Together

Use the topics in this section to learn how to upgrade an SLX device to the latest supported version of SLX-OS with the latest supported version of TPVM.

Requirement for SCP connections

The firmware server must support more than 10 unauthenticated SCP connections. You can ensure this requirement by specifying an appropriate value for '#MaxStartups 10:30:100' in the /etc/ssh/sshd_config file on the firmware server.

The following is an example of an appropriate value:

Full is greater than Start and Start is greater than the number of devices in the fabric.

  • Run $ sudo systemctl daemon-reload to restart the sshd service for the changes to the /etc/ssh/sshd_config file to take effect..
  • Run $ sudo systemctl restart sshd.service to restart the sshd service.
  • Restarting the sshd service does not affect any connected SSH sessions.
