Parameter
suite-number: Algorithm suite number ranging from 0 to 12. This argument
stands for the algorithm suite used to encrypt session control packets, whose
available values are described as follows:
0 Without protection
1 DES_MD5_DHGROUP1
2 DES_MD5_DHGROUP2
3 DES_SHA1_DHGROUP1
4 DES_SHA1_DHGROUP2
5 3DES_MD5_DHGROUP1
6 3DES_MD5_DHGROUP2
7 3DES_SHA1_DHGROUP1
8 3DES_SHA1_DHGROUP2
9 AES128_MD5_DHGROUP1
10 AES128_MD5_DHGROUP2
11 AES128_SHA1_DHGROUP1
12 AES128_SHA1_DHGROUP2
Description
Use the session algorithm-suite command to specify the algorithm suite a
session uses.
Use the undo session algorithm-suite command to revert to the default
algorithm suite.
Algorithm suite 1 is used by session control packets by default, which stands for
DES (for encryption), MD5 (for authentication), and DH-GROUP1 (for key
negotiation).
Example
# Specify not to encrypt control packets (provide 0 for the suite-number
argument).
