Switch(config)#ssh-server enable
1.2.14 ssh-server host-key create rsa
Command: ssh-server host-key create rsa [modulus < modulus >]
Function: Generate new RSA host key.
Parameter: modulus is the modulus which is used to compute the host key; valid range
is 768 to 2048. The default value is 1024.
Command mode: Global Mode
Default: The system uses the key generated when the ssh-server is started at the first
time.
Usage Guide: This command is used to generate the new host key. When SSH client
logs on the server, the new host key is used for authentication. After the new host key is
generated and ―write‖ command is used to save the configuration, the system uses this
key for authentication all the time. Because it takes quite a long time to compute the new
key and some clients are not compatible with the key generated by the modulus 2048, it is
recommended to use the key which is generated by the default modulus 1024.
Example: Generate new host key.
Switch(config)#ssh-server host-key create rsa
1.2.15 ssh-server max-connection
Command: ssh-server max-connection {<max-connection-number>|default}
Function: Configure the max connection number supported by the SSH service of the
switch.
Parameters: <max-connection-number>: the max connection number supported by the
SSH service, ranging from 5 to 16. The default option will restore the default configuration.
Default: The system default value of the max connection number is 5.
Command Mode: Global Mode
Usage Guide: None.
Example: Set the max connection number supported by the SSH service as 10.
Switch(config)#ssh-server max-connection 10
1.2.16 ssh-server timeout
Command: ssh-server timeout <timeout>
no ssh-server timeout
Function: Configure timeout value for SSH authentication; the ―no ssh-server timeout‖
