disable ssl
Purpose
To disable the SSL function on the Switch.
Syntax
disable ssl {ciphersuite {RSA_with_RC4_128_MD5 | RSA_with_3DES_EDE_CBC_SHA |
DHE_DSS_with_3DES_EDE_CBC_SHA | RSA_EXPORT_with_RC4_40_MD5}}
Description
This command will disable SSL on the Switch and can be used to disable any one or
combination of listed ciphersuites on the Switch.
Parameters
ciphersuite
– A security string that determines the exact cryptographic parameters, specific
encryption algorithms and key sizes to be used for an authentication session. The user may
choose any combination of the following:
•
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.
•
RSA_with_3DES_EDE_CBC_SHA
– This ciphersuite combines the RSA key
exchange, CBC Block Cipher 3DES_EDE encryption and the SHA Hash Algorithm.
•
DHE_DSS_with_3DES_EDE_CBC_SHA
– This ciphersuite combines the DSA Diffie
Hellman key exchange, CBC Block Cipher 3DES_EDE encryption and SHA Hash
Algorithm.
•
RSA_EXPORT_with_RC4_40_MD5
– This ciphersuite combines the RSA Export
key exchange, stream cipher RC4 encryption with 40-bit keys.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To disable the SSL status on the Switch:
DGS-3450:admin# disable ssl
Command: disable ssl
Success.
DGS-3450:admin#
To disable ciphersuite RSA_EXPORT_with_RC4_40_MD5 only:
DGS-3450:admin# disable ssl ciphersuite RSA_EXPORT_with_RC4_40_MD5
Command: disable ssl ciphersuite RSA_EXPORT_with_RC4_40_MD5
Success.
DGS-3450:admin#
config ssl cachetimeout
Purpose
Used to configure the SSL cache timeout.
Syntax
config ssl cachetimeout <value 60-86400>
Description
This command 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.
Parameters
<value 60-86400>
– Enter a timeout value between
60
and
86400
seconds to specify the total
time an SSL key exchange ID stays valid before the SSL module will require a new, full SSL
negotiation for connection. The default cache timeout is 600 seconds
Restrictions
Only Administrator and Operator-level users can issue this command.
