Transferring Files to and from a Controller
Controllers have built-in utilities for uploading and downloading various files. Follow the instructions
in these sections to import files using either the controller GUI or CLI:
•
Downloading Device Certificates, page 9-13
•
Downloading CA Certificates, page 9-16
•
•
Uploading and Downloading Configuration Files, page 9-21
Downloading Device Certificates
Each wireless device (controller, access point, and client) has its own device certificate. For example,
the controller is shipped with a Cisco-installed device certificate. This certificate is used by EAP-FAST
(when not using PACs), EAP-TLS, PEAP-GTC, and PEAP-MSCHAPv2 to authenticate wireless clients
during local EAP authentication. However, if you wish to use your own vendor-specific device
certificate, it must be downloaded to the controller.
Note
See the
“Configuring Local EAP” section on page 5-38
for information on configuring local EAP.
Follow the instructions in this section to download a vendor-specific device certificate to the controller
through the GUI or CLI. However, before you begin, make sure you have a TFTP or FTP server available
for the certificate download. Keep these guidelines in mind when setting up a TFTP or FTP server:
•
If you are downloading through the service port, the TFTP or FTP server must be on the same subnet
as the service port because the service port is not routable, or you must create static routes on the
controller.
•
If you are downloading through the distribution system network port, the TFTP or FTP server can
be on the same or a different subnet because the distribution system port is routable.
•
A third-party TFTP or FTP server cannot run on the same computer as WCS because the WCS
built-in TFTP or FTP server and the third-party TFTP or FTP server require the same
communication port.
Note
All certificates downloaded to the controller must be in PEM format.
