Default: The number of times for retrying SSH authentication is 3 by default.
Example: Set the number of times for retrying SSH authentication to 5.
Switch(Config)#ssh-server authentication-retries 5
2.2.4.3.2 ssh-server enable
Command: ssh-server enable
no ssh-server enable
Function: Enable SSH function on the switch; the "no ssh-server enable" command
disables SSH function.
Command mode: Global Mode
Default: SSH function is disabled by default.
Usage Guide: In order that the SSH client can log on the switch, the users need to
configure the SSH user and enable SSH function on the switch.
Example: Enable SSH function on the switch.
Switch(Config)#ssh-server enable
2.2.4.3.3 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
2.2.4.3.4 ssh-server timeout
Command: ssh-server timeout <timeout>
no ssh-server timeout
Function: Configure timeout value for SSH authentication; the "no ssh-server timeout"
command restores the default timeout value for SSH authentication.
Parameter: <timeout> is timeout value; valid range is 10 to 600 seconds.
Command mode: Global Mode
