The fields that can be configured are described below:
Parameter Description
SSL State
Use the radio buttons 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.

To set up the SSL cipher suite function on the Switch, configure the parameters in the SSL Cipher suite Settings
section described below:
Parameter Description
RSA with
RC4_128_MD5
This cipher suite combines the RSA key exchange, stream cipher RC4 encryption with
128-bit keys and the MD5 Hash Algorithm. Use the radio buttons to enable or disable
this cipher suite. This field is Enabled by default.
RSA with 3DES EDE
CBC SHA
This cipher suite combines the RSA key exchange, CBC Block Cipher 3DES_EDE
encryption and the SHA Hash Algorithm. Use the radio buttons to enable or disable
this cipher suite. This field is Enabled by default.
DHS DSS with 3DES
EDE CBC SHA
This cipher suite combines the DSA Diffie Hellman key exchange, CBC Block Cipher
3DES_EDE encryption and SHA Hash Algorithm. Use the radio buttons to enable or
disable this cipher suite. This field is Enabled by default.
RSA EXPORT with RC4
40 MD5
This cipher suite combines the RSA Export key exchange and stream cipher RC4
encryption with 40-bit keys. Use the radio buttons to enable or disable this cipher
suite. This field is Enabled by default.
Click the Apply button to accept the changes made.
To download SSL certificates, configure the parameters in the SSL Certificate Download section described below.
Parameter Description
Server IP Address
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 the Download button to download the SSL certificate based on the information entered.
NOTE: Certain implementations concerning the function and configuration of SSL are not available on
the web-based management of this Switch and need to be configured using the command line
interface.
NOTE: Enabling the SSL command will disable the web-based switch management. To log on to the
Switch again, the header of the URL must begin with https://. Entering anything else into the
address field of the web browser will result in an error and no authentication will be granted.
