h3c E352 ssh配置

我的交换机配置如下：

rsa local-key-pair create

---------------------------

local-user admin password cipher (E<)'>D,BW'Q=^Q`MAF4<1!! service-type ssh telnet terminal level 3

---------------------------------

 snmp-agent snmp-agent local-engineid 800063A20023893C17616877

 snmp-agent community read public123 snmp-agent community write private123

 snmp-agent sys-info version all 

 snmp-agent target-host trap address udp-domain 10.200.0.68 params securityname public123 

ssh user admin authentication-type password ssh user admin service-type stelnet 

user-interface aux 0 

user-interface vty 0 

 user privilege level 3 

 set authentication password cipher :D84\K7*%0N,YWX*NZ55OA!! 

user-interface vty 1 4 

 authentication-mode scheme 

 user privilege level 3 

 set authentication password cipher (E<)'>D,BW'Q=^Q`MAF4<1!!

配置完成后，用SecureCRTP打开输入用户和密码后出现提示：

The server has disconnected with an error. Server message reads: A protocol error occurred. The connection is closed by SSH Server Current FSM is SSH_Main_Disconnect

请问是什么情况，我的配置哪里有问题。
