7.2 Z9100-ON spine switch configuration
The following configuration details are for Z9100-Spine1 and Z9100-Spine2 in Figure 14.
Note: On Z9100-ON switches, Telnet is enabled and SSH is disabled by default. Both services require the
creation of a non-root user account to login. If needed, it is a best practice to use SSH instead of Telnet for
security. SSH can optionally be enabled with the command: (conf)#ip ssh server enable.
A user account can be created to access the switch via SSH with the command
(conf)#username ssh_user sha256-password ssh_password
First, configure the serial console enable password and disable Telnet.
