rsa_des_cbc_sha: Specifies the key exchange algorithm of RSA, the data encryption algorithm of
DES_CBC, and the MAC algorithm of SHA.
rsa_rc4_128_md5: Specifies the key exchange algorithm of RSA, the data encryption algorithm of
128-bit RC4, and the MAC algorithm of MD5.
rsa_rc4_128_sha: Specifies the key exchange algorithm of RSA, the data encryption algorithm of
128-bit RC4, and the MAC algorithm of SHA.
Description
Use the prefer-cipher command to specify the preferred cipher suite for an SSL client policy.
Use the undo prefer-cipher command to restore the default.
By default, the preferred cipher suite for an SSL client policy is rsa_rc4_128_md5.
Related commands: display ssl client-policy.
Examples
# Set the preferred cipher suite for SSL client policy policy1 to rsa_aes_128_cbc_sha.
<Sysname> system-view
[Sysname] ssl client-policy policy1
[Sysname-ssl-client-policy-policy1] prefer-cipher rsa_aes_128_cbc_sha
session
Syntax
session { cachesize size | timeout time } *
undo session { cachesize | timeout } *
View
SSL server policy view
Parameters
size: Maximum number of cached sessions, in the range 100 to 1,000.
time: Caching timeout time in seconds, in the range 1,800 to 72,000.
Description
Use the session command to set the maximum number of cached sessions and the caching timeout
time.
Use the undo session command to restore the default.
By default, the maximum number of cached sessions is 500 and the caching timeout time is 3,600
seconds.
The process of the session parameters negotiation and session establishment by using the SSL
handshake protocol is quite complicated. SSL allows reusing the negotiated session parameters to
establish sessions. Therefore, the SSL server needs to maintain information about existing sessions.
Note that the number of sessions and the time that the session information will be maintained are
limited:
z If the number of sessions in the cache reaches the maximum, SSL rejects to cache new sessions.
