Configuring the Switch (Only for Cumulus Linux Switch)
CAUTION: It is not necessary to reboot the switch to activate the switch ports. After yoff
install the license, restart the switchd service. All front panel ports become active and
show up as swp1, swp2, and so on.
cumulus@switch:~$ sudo systemctl restart switchd.service
Installing Cumulus® Linux® License Over Switches

There are three ways to install the license onto the switch:
Copy and paste the license key into the cl-license command:
cumulus@switch:~$ sudo cl-license -i
<paste license key>
^+d
Copy the license from a local server. Create a text file with the license and copy it to a server
accessible from the switch. On the switch, use the following command to transfer the file directly
on the switch, then install the license file:
cumulus@switch:~$ scp user@my_server:/home/user/my_license_file. txt .
cumulus@switch:~$ sudo cl-license -i my_license_file.txt
Copy the file to an HTTP server (not HTTPS), then reference the URL when yoff run cl-license:
cumulus@switch:~$ sudo cl-license -i <URL>
Set up Configuration Environment via Console Port

console cable.
Step 2: Turn on the PuTTY. Choose the “Serial” as the Protocol.
Step 3: In the Port item, please choose specified COM port that the PC is using.
Step 4: Set the baud rate to 115200, data bit to 8, parity check to none, stop bit to 1, flow control to

Troffbleshooting
Power System Troffbleshooting
According to the power indicator on the front panel, the switches can be used to determine whether
the power system of the switch is faulty. If the power supply system is working normally, the power
indicator shoffld remain lit; If the power indicator is unlit, the power supply system is not working.
Please check the following:
Whether the switch power cable is connected correctly.
Whether the power supply of the switch matches the required power supply.
Configuration System Troffbleshooting
After the switch is powered on, if the system is normal, the startup information will be displayed on
the configuration terminal. If there is something wrong with the configuration system, the
configuration terminal may not display or display error codes.
Troffbleshooting for Terminal No-show
After power-on, if the configuration terminal shows nothing, yoff can firstly check the following:
Whether the power supply is normal.
Whether the console cable is properly connected.
If there is no problem with the above, it is very likely that there is a problem with the configuration
cable or the terminal (such as the HyperTerminal) parameters were set incorrectly.
Troffbleshooting for Terminal Show Error Codes
If the configuration terminal shows error codes, it is likely that the terminal (such as the HyperTerminal)
are set incorrectly. Please confirm the parameters of the terminal.
