Uploading Certificates

A certificate is a digital file that certifies the identity of the organization or products of the organization. It is also used to establish your credentials for any Web transactions. It contains the organization name, a serial number, expiration date, a copy of the certificate-holder's public key, and the digital signature of the certificate-issuing authority so that a recipient can ensure that the certificate is real.

Instant supports the following certificate files:

Auth server or captive portal server certificate: PEM format with passphrase (PSK)
CA certificate: PEM or DER format

In the current release, IAP supports uploading of a customized certificate for internal captive portal server.

This section describes the following procedures:

Loading Certificates through Instant CLI

To upload a certificate:

(Instant AP)# copy tftp {<ip-address> <filename> cpserver cert <password> format {p12|pem} |system {1xca [format {der|pem}]|1xcert <passsword>[format {p12|pem}]}

Loading Certificates through AirWave

You can manage certificates using the AirWave. The AMP directly provisions the certificates and performs basic certificate verification (such as certificate type, format, version, serial number and so on), before accepting the certificate and uploading to an IAP network. The AMP packages the text of the certificate into an HTTPS message and sends it to the Virtual Controller. After the VC receives this message, it draws the certificate content from the message, converts it to the right format, and saves it on the RADIUS server.

To load a certificate in AirWave:

1. Navigate to Device Setup > Certificate and then click Add to add a new certificate. The Certificate window is displayed.
2. Enter the certificate Name, and click Choose File to browse and upload the certificate.

3. Select the appropriate Format that matches the certificate file name. Select Server Cert for certificate Type, and provide the passphrase if you want to upload a Server certificate. Select either Intermediate CA or Trusted CA certificate Type, if you want to upload a CA certificate.
