SSH Commands

267

Syntax

crypto key generate rsa

Default Configuration

RSA key pairs do not exist.

Command Mode

Global Configuration mode

User Guidelines

• RSA keys are generated in pairs: one public RSA key and one private RSA key. If the Ethernet

Switch Module already has RSA keys, a warning and prompt to replace the existing keys with

new keys is displayed.

• The maximum supported size for the RSA key is 2048 bits.
• This command is not saved in the startup configuration; however, the keys generated by this

command are saved in the FLASH. The SSH keys can be displayed with the

show crypto key

mypubkey rsa

command.

• This command may take up to 5 minutes to execute.

Example

The following example generates RSA key pairs.

ip ssh pubkey-auth

The

ip ssh pubkey-auth

Global Configuration mode command enables public key authentication

for incoming SSH sessions. To disable this function, use the

no

form of this command.

Syntax

ip ssh pubkey-auth
no ip ssh pubkey-auth

Default Configuration

The function is disabled.

Command Mode

Global Configuration mode

User Guidelines

There are no user guidelines for this command.
