HPE FlexFabric 7900 Series Security Command Reference page 280

dscp dscp-value: Specifies the DSCP value in the IPv4 SSH packets sent by the SSH client, in the
range of 0 to 63. The default value is 48. The DSCP value determines the transmission priority of the
packet.
escape character: Specifies an escape character. By default, the escape character is a tilde (~).
publickey keyname: Specifies the host public key of the server, 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 for SSH packets. By default, the SSH
packets use the primary IPv4 address of the output interface specified in the routing entry as the
source IP address. For successful Stelnet connections, use one of the following methods:
•
Specify the loopback interface as the source interface.
•
Specify the IP address of the loopback interface 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 of SSH packets.
ip ip-address: Specifies a source IPv4 address.
Usage guidelines
The combination of an escape character and a dot (.) works as an escape sequence for fast
terminating an SSH connection. For the escape sequence to take effect, you must enter it at the very
beginning of a line. If you have entered other characters or performed operations in a line, enter the
escape sequence in the next line.
As a best practice, use the default escape character (~). Do not use any characters in SSH
usernames as the escape character.
Examples
# Establish a connection to the IPv4 Stelnet server 3.3.3.3 and specify the public key of the server as
svkey. The Stelnet client uses publickey authentication. Specify the dollar sign ($) as the escape
character. Use the following algorithms:
•
Preferred key exchange algorithm dh-group14.
•
Preferred server-to-client encryption algorithm aes128.
•
Preferred client-to-server HMAC algorithm sha1.
•
Preferred server-to-client HMAC algorithm sha1-96.
•
Preferred compression algorithm zlib.
