Transfer an existing certificate to the switch
You can transfer a certificate file to the switch.
For the switch to accept HTTPS connections from a device, the switch requires a public key
certificate.
You can generate a certificate externally (for example, offline) and transfer it to the
switch.
Before you transfer a file from a TFTP server to the switch, the following conditions must be
true:
• The file to download from the
TFTP server is on the server in the appropriate directory.
• The file is in the correct format.
• The switch contains a path to the
TFTP server.
Note: Before you can transfer a certificate, you must disable HTTPS (see
Configure the HTTPS settings on page 357) and log back in to the
device UI over an HTTP session. After you transfer the certificate, you
can reenable HTTPS and log back in to the device UI over an HTTPS
session.
To configure the certificate transfer settings for HTTPS sessions:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is of
f-network using an Ethernet cable.
2. Launch a web browser.
