HP FlexFabric 7900 Series Command Reference Manual page 208

dsa: Specifies the public key algorithm dsa.
•
• rsa: Specifies the public key algorithm rsa.
prefer-compress: Specifies the preferred compression algorithm between the server and the client. By
default, compression is not supported.
zlib: Specifies the compression algorithm zlib.
prefer-ctos-cipher: Specifies the preferred client-to-server encryption algorithm. The default is aes128.
Algorithms des, 3des, aes128, and aes256 are arranged in ascending order in the aspects of security
strength and calculation time.
• 3des: Specifies the encryption algorithm 3des-cbc.
aes128: Specifies the encryption algorithm aes128-cbc.
•
aes256: Specifies the encryption algorithm aes256-cbc.
•
des: Specifies the encryption algorithm des-cbc.
•
prefer-ctos-hmac: Specifies the preferred client-to-server HMAC algorithm. The default is sha1.
Algorithm sha1 features stronger security but costs more time in calculation than md5.
md5: Specifies the HMAC algorithm hmac-md5.
•
md5-96: Specifies the HMAC algorithm hmac-md5-96.
•
• sha1: Specifies the HMAC algorithm hmac-sha1.
sha1-96: Specifies the HMAC algorithm hmac-sha1-96.
•
prefer-kex: Specifies the preferred key exchange algorithm. The default is dh-group-exchange in
non-FIPS mode and dh-group14 in FIPS mode. Algorithm dh-group14 features stronger security but costs
more time in calculation than dh-group1.
dh-group-exchange: Specifies the key exchange algorithm diffie-hellman-group-exchange-sha1.
•
dh-group1: Specifies the key exchange algorithm diffie-hellman-group1-sha1.
•
dh-group14: Specifies the key exchange algorithm diffie-hellman-group14-sha1.
•
prefer-stoc-cipher: Specifies the preferred server-to-client encryption algorithm. The default is aes128.
prefer-stoc-hmac: Specifies the preferred server-to-client HMAC algorithm. The default is sha1.
dscp dscp-value: Specifies the DSCP value in the IPv4 SFTP packets sent by the SFTP client, in the range
of 0 to 63. The default value is 48. The DSCP value determines the transmission priority of the packet.
publickey keyname: Specifies the host public key of the sever, which is used to authenticate the server.
The keyname argument is a case-insensitive string of 1 to 64 characters.
source: Specifies a source IP address or source interface to connect to the server. By default, the packet
to send gets the primary IP address of its outbound interface from the routing table and uses it as the
source IP address. To avoid the communication failure between the client and the server due to interface
faults, use the specified loopback interface as the source interface, and either IP address of the two
interfaces as the source IP address.
interface interface-type interface-number: Specifies a source interface by its type and number. The
primary IPv4 address of this interface is the source IP address to send packets.
ip ip-address: Specifies a source IPv4 address.
Usage guidelines
When the server adopts publickey authentication to authenticate a client, the client must get the local
private key for digital signature. Because publickey authentication uses RSA or DSA algorithm, you must
