What is OS Security for NEs?
NE management using anti-theft mode
Anti-theft mode can be enabled on compatible devices. Enabling anti-theft mode ensures that if the device is stolen, it cannot be reconfigured and reused.
When anti-theft mode is enabled, after each reboot the device is locked, requiring the OS security password before allowing access to the configuration commands, preventing the device from being used in a new network deployment.
See the NE documentation for information about configuring an OS security password on the device.
