From the forum:

I have several servers connected to my VyOS router over USB-to-Serial adapters to provide out-of-band access, like so:

service {
  console-server {
    device usb0b4p1.0 {
       description ServerA
       speed 9600
   }
   device usb0b5p1.0 {
       description ServerB
       speed 115200
   }
   device usb0b10p1.0 {
       description ServerC
       speed 115200
   }
  }
}

This works, but to connect to Server A, I need to run connect console usb0b4p1.0 - so inevitably I need to configure; show service console-server to remember which adapter maps to which server.

It would be much easier if I could do connect console ServerA
