This section describes how the device
determines whether to use ZTP or ZTP+ for configuration.
Connection
Once the SLX device is connected to the network, it uses DHCP to obtain an IP
address. After receiving an IP address and DNS information via DHCP, the device
tries to connect to XMC using the following means:
extremecontrol.<customerDomainName>
devices.extremenetworks.com
check DHCP options for original ZTP support
When an SLX device comes up in ZTP mode, the native ZTP state machine uses the following
procedure to deterimine which method to use for configuration; ZTP or ZTP+.
The CloudConnector plugin is
launched in ZTP mode.
The DHCP options and network
configuration are received from the DHCP Server.
If option 66 and 67 are
received, proceed with native ZTP.
If the CloudConnector module
discovers XMC in the network, proceed with ZTP+.
If option 66 and 67 are
received but XMC is not discovered, then proceed with native ZTP state
machine.
You can exit ZTP and ZTP+ mode at any point using the dhcp ztp cancel
command.
The diagram below shows the ZTP to ZTP+ operational flow.
ZTP to ZTP+ Operational Flow
ZTP+ is functional only in the factory default or ZTP mode. On subsequent reboots
with ZTP mode disabled, the CloudConnector will not be launched.
