Changing the switch configuration is not difficult, but can negatively impact the operation of the switch if done incorrectly. Use caution and make a backup of the existing configuration to minimize the risk. Changes take effect immediately, but are not automatically saved to nonvolatile memory, which is required for changes to persist through a restart. This document does not provide complete instructions. For more details about network architecture, refer to the Metasys IP Networks for BACnet/IP Controllers Technical Bulletin (LIT-12012458) and standard Cisco switch configuration documentation.

For small changes, use physical access to the switch. Eject the SD card, put it in your laptop, create a backup copy of the file, and edit the original file directly. You need to restart the switch after you re-insert the updated SD card in order for the changes to the configuration file to take effect. This approach is suitable for tasks including changing the hostname. With care, you can edit the configuration file to complete more complicated tasks, including changing the BACnet UDP port number. However, it may be easier to run the configuration tool again.

Remember that the default security setting is to report all changes to switch configuration and all removal and insertion of SD cards.

There are two passwords. The first password is for logon; the second is for elevation of privileges, including editing the switch configuration. Use the console port on the switch to connect to the command line. To change the configuration, complete the following steps:

  1. Log on to the switch.
  2. Enter enable
  3. Enter the password for elevation of privilege.
  4. Enter config terminal, to set the console to take configuration commands from terminal.

From this point on, you are manually configuring the switch and need to exercise caution.
