source: Specifies a source IP address or source interface for IPv6 SSH packets. By default, the 
device automatically selects a source address for IPv6 SSH packets in compliance with RFC 3484. 
For successful IPv6 Stelnet connections, use one of the following methods: 
  Specify the loopback interface as the source interface. 
  Specify the IPv6 address of the loopback interface as the source IPv6 address. 
interface interface-type interface-number: Specifies a source interface by its type and number. The 
IPv6 address of this interface is the source IP address of the IPv6 SSH packets. 
ipv6 ipv6-address: Specifies a source IPv6 address. 
Usage guidelines 
If the client and the server have negotiated to use certificate authentication, the client must verify the 
server's certificate. For the client to correctly get the server's certificate, you must specify the server's 
PKI domain on the client by using the server-pki-domain domain-name option. The client uses the 
CA certificate stored in the specified PKI domain to verify the server's certificate and does not need to 
save the server's public key before authentication. If you do not specify the server's PKI domain, the 
client uses the PKI domain of its own certificate to verify the server's certificate. 
The combination of an escape character and a dot (.) works as an escape sequence. This escape 
sequence  is typically used to quickly terminate an  SSH connection when the server reboots or 
malfunctions. 
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. HPE recommends that you use the default escape character (~). Do not use any character in 
SSH usernames as the escape character. 
Examples 
# Use the 192-bit Suite B algorithms to establish a connection to the Stelnet sever 2000::1. Specify 
the client's PKI domain and the server's PKI domain as clientpkidomain and serverpkidomain, 
respectively. 
<Sysname> ssh2 ipv6 2000::1 suite-b 192-bit pki-domain clientpkidomain server-pki-domain 
serverpkidomain 
New command: ssh2 suite-b 
Use ssh2 suite-b to establish a connection to an IPv4 Stelnet server based on Suite B algorithms. 
Syntax 
ssh2  server  [  port-number  ] [ vpn-instance  vpn-instance-name  ]  suite-b  [  128-bit  |  192-bit  ] 
pki-domain domain-name [ server-pki-domain domain-name ] [ prefer-compress zlib ] [ dscp 
dscp-value | escape character | source { interface interface-type interface-number | ip ip-address } ]
