Parameter Description
Certificate Type Select Local to specify certificate type.
Server IP Enter the IPv4 address of the TFTP server where the certificate files are located.
Certificate File Name Enter the path and the filename of the certificate file to download. This file must have a .der
extension. (Ex. c:/cert.der)
Key File Name Enter the path and the filename of the key file to download. This file must have a .der
extension (Ex. c:/pkey.der)
Click Apply to implement changes made.
SSL Configuration
This screen will allow the user to enable SSL on the Switch and implement any one or combination of listed ciphersuites on the
Switch. A
ciphersuite is a security string that determines the exact cryptographic parameters, specific encryption algorithms and
key sizes to be used for an authentication session. The Switch possesses four possible ciphersuites for the SSL function, which are
all enabled by default. To utilize a particular ciphersuite, disable the unwanted ciphersuites, leaving the desired one for
authentication.
When the SSL function has been enabled, the web will become disabled. To manage the Switch through the web based
management while utilizing the SSL function, the web browser must support SSL encryption and the header of the URL must
begin with https://. (Ex. https://xx.xx.xx.xx) Any other method will result in an error and no access can be authorized for the web-
based management.
To view the following window, click Security > SSL :
Figure 9- 28. SSL Configuration and Ciphersuite menu
To set up the SSL function on the Switch, configure the following parameters and click Apply .
Parameter Description
Configuration
SSL Status Use the pull down menu to enable or disable the SSL status on the switch. The default is
Disabled .
Cache Timeout (60-
86400) This field will set the time between a new key exchange between a client and a host using
the SSL function. A new SSL session is established every time the client and host go
through a key exchange. Specifying a longer timeout will allow the SSL session to reuse
the master key on future connections with that particular host, therefore speeding up the
negotiation process. The default setting is 600 seconds.
SSL Ciphersuite
RSA with RC4 128 MD5 This ciphersuite combines the RSA key exchange, stream cipher RC4 encryption with 128-
bit keys and the MD5 Hash Algorithm. Use the pull down menu to enable or disable this
ciphersuite. This field is
Enabled by default.
