System Information

VyOS features a rich set of operational level commands to retrieve arbitrary information about your running system. For more information on the VyOS command line interface (CLI), see Command Line Interface.

Hardware

USB

In the past, serial interfaces were defined as ttySx and ttyUSBx where x was the instance number. However, the mapping of USB-based serial interfaces can change from one system boot to another, depending on which driver the operating system loads first. This inconsistency can be problematic when you use multiple serial interfaces. For example, both console-server connections and a serial-backed WWAN.

To address this issue, and because many low-cost USB-to-serial converters do not have a programmed serial number, VyOS now identifies USB-to-serial interfaces by the USB root bridge and the bus they connect to. This approach is similar to the network interface naming conventions used in recent Linux distributions.

show hardware usb

Retrieve a tree-like representation of all connected USB devices.

Note

If a device is unplugged and plugged in again, it is assigned a new Port, Dev, and If.

show hardware usb serial

Retrieve a list and description of all connected USB serial devices. The device name displayed, (for example usb0b2.4p1.0), can be used directly when accessing the serial console as console-server device.

Version

show version

Return the currently running VyOS version and build information. This includes the name of the release train, e.g., sagitta on VyOS 1.4, and circinus on VyOS 1.5.
