Upgrading SLX-OS, TPVM, and XCO Together

Use the topics to learn how to upgrade an SLX device to the latest supported version of SLX-OS and TPVM.

Requirement for SCP connections

Note

For details on updating TPVM password while XCO is running, see ExtremeCloud Orchestrator Security Guide, 3.3.0 .

The firmware server must support more than 10 unauthenticated SCP connections. To ensure this requirement, specify an appropriate value of '#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.
