User Manual

Chapter 1. Commands for Basic Switch Configuration 31

www.qtech.ru

 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

1.2.21 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

1.2.22 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
