PLANET WGSD-1022 - Manual (Page 278)

User Guidelines
If encryption keys are not generated, the SSH server is in standby until the keys are generated. To
generate SSH server keys, use the commands crypto key generate rsa, and crypto key generate dsa.
Example
The following example enables the device to be configured from a SSH server.
Console (config)# ip ssh server
5.22.3 crypto key generate dsa
The ip ssh server global configuration command generates DSA key pairs.
Syntax
crypto key generate dsa
Default Configuration
DSA key pairs do not exist.
Command Mode
Global Configuration mode
User Guidelines
DSA keys are generated in pairs: one public DSA key and one private DSA key. If the device already has
DSA keys, a warning and prompt to replace the existing keys with new keys is displayed.
The maximum supported size for the DSA key is 1,024.
This command is not saved in the startup configuration; however, the keys generated by this command
are saved in the running configuration, which is never displayed to the user or backed up to another
device.
This command may take a considerable period of time to execute.
DSA key size is 2048 bits.
Example
The following example generates DSA key pairs.
Console (config)# crypto key generate dsa
