Any serial activity is received, on either console/usb console or device serial ports (RJ45). | ||||
Notes:
- The amber LED signal threshold configuration is set to 50%.of normal signal strength.
- CM8100 series devices do not have a cloud LED, therefore, no LED indication is available for LSP or Lighthouse.
