Dell MX9116n EMC SmartFabric OS10 User Guide - Page 940

Default The SSH server uses default public key lengths for client authentication: • RSA key: 2048 bits • ECDSA key : 256 bits • Ed25519 key: 256 bits Command Mode EXEC Usage Information If necessary, you can regenerate the public keys used by the SSH server with a customized bit size. You cannot change the default size of the Ed25519 key. The crypto ssh-key generate command is available only to the sysadmin and secadmin roles. Example OS10# crypto ssh-key generate rsa 4096 Host key already exists. Overwrite [confirm yes/no]:yes Generated 4096-bit RSA key OS10# Supported Releases 10.4.1.0 or later disable Lowers the privilege level. Syntax Parameters disable privilege-level • privilege-level-Enter the privilege level, from 0 to 15. Defaults 1 Command Mode Privileged EXEC Usage Information If you do not specify a privilege level, the system assigns level 1. Example OS10# disable Supported Releases OS10# disable 6 10.4.3.0 or later enable Enables a specific privilege level. Syntax Parameters enable privilege-level • privilege-level-Enter the configured privilege level, from 0 to 15. Defaults 15 Command Mode Exec Usage Information Dell EMC Networking recommends configuring a password for privilege level 15 using the enable password command. If you do not configure a password for a level, you can switch to that level without entering a password, unless a password is configured for a highest intermediate level. If you configure a password for an intermediate level, enter that password when prompted. To access privilege level 15, you must configure the enable password command. If you do not configure a password for privilege level 15, you cannot enter level 15. For privilege levels 0 to 14, the enable password command is optional. Privilege levels inherit all permitted commands from all lower levels. For example, if you log in to privilege level 10 using the enable 10 command, all commands that are assigned to privilege level 10 and lower are available for use. 940 Security
