58 Leaf-Spine Deployment and Best Practices Guide | Version 1.0

10.1 Z9100-ON leaf switch configuration

The following section outlines the configuration commands issued to the Z9100-ON leaf switches to build the

topology in Figure 17. The commands detailed below are for L2-Leaf1-Z9100 and L2-Leaf2-Z9100. The

configuration commands for L2-Leaf3-Z9100 and L2-Leaf4-Z9100 are similar and are provided in the

attachments.

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.

Set the hostname, configure the OOB management interface and default gateway. Enable LLDP. Enable

RSTP as a precaution.

Note: In this layer 2 topology, the RSTP root bridge is configured at the spine level.
