Usage Guidelines
While the
setup
command contains no arguments or keywords, the Basic System Configuration Dialog prompts you for complete setup information, as shown in the Examples section.
The Basic System Configuration Dialog assumes the factory defaults. Keep this in mind when using it to modify an existing configuration.
All changes made to your configuration are summarized for you at the completion of the setup sequence with an option to save the changes or not.
You can exit the setup sequence at any point by pressing Ctrl-C.
Examples
This example shows how to use the setup command to create or modify a basic system configuration:
Enter HA role[primary/secondary]: primary Enter network-uplink type <1-4>: 1. Ports 1-2 carry all management, control and data vlans 2. Ports 1-2 management and control, ports 3-6 data 3. Ports 1-2 management, ports 3-6 control and data 4.

ERROR: CLI error: Domain id can be configured only once Warning! Mandatory reload needed for change to take effect. Save configuration before reload, else Nexus1010 HA will break! [########################################] 100% ---- Basic System Configuration Dialog ---- This setup utility will guide you through the basic configuration of the system. Setup configures only enough connectivity for management *Note: setup is mainly used for configuring the system initially, when no configuration is present. So setup always assumes system defaults and not the current system configuration values. Press Enter at anytime to skip a dialog. Use ctrl-c at anytime to skip the remaining dialogs. Would you like to enter the basic configuration dialog (yes/no): y Create another login account (yes/no) [n]: n Configure read-only SNMP community string (yes/no) [n]: Configure read-write SNMP community string (yes/no) [n]: Enter the VSA name [Nexus1010]: Continue with Out-of-band (mgmt0) management configuration?

switch# ssh 10.10.1.1 vrf management The authenticity of host '10.10.1.1 (10.10.1.1)' can't be established. RSA key fingerprint is 9b:d9:09:97:f6:40:76:89:05:15:42:6b:12:48:0f:d6. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '10.10.1.1' (RSA) to the list of known hosts.

To generate the key pair for the switch, which is used if SSH server is enabled, use the
ssh key
command. To remove the SSH server key, use the
no
form of this command.
ssh key

[
force
] |

Syntax Description
dsa
|
Specifies the Digital System Algrorithm (DSA) SSH server key.
|
force
|
(Optional) Forces the replacement of an SSH key.
|
rsa
|
Specifies the Rivest, Shamir, and Adelman (RSA) public-key cryptography SSH server key.
|
length
|
(Optional) Number of bits to use when creating the SSH server key. The range is from 768 to 2048.

Usage Guidelines
The switch uses a 1024-bit RSA key by default. The
ssh key
command allows you to choose a different algorithm (DSA) or different key strengths.
If you want to remove or replace an SSH server key, you must first disable the SSH server using the
no ssh server enable
command.
The Cisco NX-OS software supports SSH version 2.
Examples
This example shows how to create an SSH server key using DSA:
switch(config)# ssh key dsa generating dsa key(1024 bits).....
This example shows how to create an SSH server key using RSA with the default key length:
switch(config)# ssh key rsa generating rsa key(1024 bits).....
This example shows how to create an SSH server key using RSA with a specified key length:
switch(config)# ssh key rsa 768 generating rsa key(768 bits).....
This example shows how to replace an SSH server key using DSA with the
force
option:
switch(config)# no ssh server enable switch(config)# ssh key dsa force deleting old dsa key..... generating dsa key(1024 bits)..... switch(config)# ssh server enable
This example shows how to remove the DSA SSH server key:
switch(config)# no ssh server enable XML interface to system may become unavailable since ssh is disabled switch(config)# no ssh key dsa switch(config)# ssh server enable
This example shows how to remove all SSH server keys:
switch(config)# no ssh server enable XML interface to system may become unavailable since ssh is disabled switch(config)# no ssh key switch(config)# ssh server enable

Usage Guidelines
The Cisco NX-OS software uses the hostname in command-line interface (CLI) prompts and in default configuration filenames.
The
switchname
command performs the same function as the
hostname
command.
Examples
This example shows how to configure the device hostname:
switch# configure terminal switch(config)# switchname Engineering2
This example shows how to revert to the default device hostname:
Engineering2# configure terminal Engineering2(config)# no switchname
