With zero touch functionality, switches are automatically discovered on the network within minutes of when they are connected.

Zero Touch Provisioning Plus (ZTP+) enables you to deploy and configure switches in ExtremeCloud IQ Site Engine with minimal server configuration and intervention. ZTP+ enabled switches send information, such as the serial number, software version, MAC, management IP, and port information to ExtremeCloud IQ Site Engine automatically.

When the switch powers on, the DHCP Client obtains the IP address and gateway from the DHCP server, discovers the Domain Name Server, and connects the switch to ExtremeCloud IQ Site Engine.

If the switch cannot obtain an IP address from a DHCP server, it automatically assigns an IPv4 link-local address (169.254.x.x) to the management OOB port and the management VLAN by using the switch MAC address. The formula uses the second last byte of the MAC address as the third octet in the link-local IP address, and the last octet in the IP address is always .1 for the management OOB port and .4 for the management VLAN.

If you configure a manual, static IP address, the switch removes the IPv4 link-local address.

The following list provides an example of the link-local addressing:

• BaseMacAddr: 00:51:00:f9:20:00 where 0x20=32
• IP address for the management OOB port: 169.254.32.1
• IP address for the management VLAN: 169.254.32.4

ZTP+ uses HTTPS for communication between the switch and the ExtremeCloud IQ Site Engine server. The switch discovers the ExtremeCloud IQ Site Engine server by resolving the DNS name extremecontrol.<domain-name>.
