Chapter 1 Configuring Switch-Based Authentication
Configuring the Switch for Secure Copy Protocol
Configuring the Secure HTTP Client
The standard HTTP client and secure HTTP client are always enabled. A certificate authority is required
for secure HTTP client certification. This procedure assumes that you have previously configured a CA
trustpoint on the switch. If a CA trustpoint is not configured and the remote HTTPS server requires client
authentication, connections to the secure HTTP client fail.
Beginning in privileged EXEC mode, follow these steps to configure a secure HTTP client:
Use the no ip http client secure-trustpoint name to remove a client trustpoint configuration. Use the
no ip http client secure-ciphersuite to remove a previously configured CipherSuite specification for
the client.
Displaying Secure HTTP Server and Client Status
To display the SSL secure server and client status, use the privileged EXEC commands in Table 1-7 :
Configuring the Switch for Secure Copy Protocol
The Secure Copy Protocol (SCP) feature provides a secure and authenticated method for copying switch
configurations or switch image files. SCP relies on Secure Shell (SSH), an application and a protocol
that provides a secure replacement for the Berkeley r-tools.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2 ip http client secure-trustpoint name (Optional) Specify the CA trustpoint to be used if the remote HTTP server
requests client authentication. Using this command assumes that you have
already configured a CA trustpoint by using the previous procedure. The
command is optional if client authentication is not needed or if a primary
trustpoint has been configured.
Step 3 ip http client secure-ciphersuite
{[ 3des-ede-cbc-sha ] [ rc4-128-md5 ]
[ rc4-128-sha ] [ des-cbc-sha ]}
(Optional) Specify the CipherSuites (encryption algorithms) to be used
for encryption over the HTTPS connection. If you do not have a reason to
specify a particular CipherSuite, you should allow the server and client to
negotiate a CipherSuite that they both support. This is the default.
Step 4 end Return to privileged EXEC mode.
Step 5
show ip http client secure status Display the status of the HTTP secure server to verify the configuration.
Step 6 copy running-config startup-config (Optional) Save your entries in the configuration file.
