TitleZero-Touch Provisioning With EXOS, and Netsight
Configure Zero-Touch Provisioning (ZTP) on EXOS so Netsight will discover the device using DHCP option 125.  Once the device is discovered, firmware and configuration can be loaded through Netsight.
  • EXOS 15.7 and newer
  • Zero-Touch Provisioning
  • Netsight
  • Windows Server 2003 and 2012 (DHCP Server)
When a switch with v15.7 or newer boots up in factory default, it will request an IP address using DHCP. This will be done alternatively through the mgmt port and any connected port in the default VLAN.
  1. Program your DHCP server to send back Option 125 with the address of the NetSight server.
Option 125 should contain the following:
0x00 0x00 0x15 0xf8 0x06 0x01 0x04 and then the IP address of the server.

So if your server has an IP address of, the string returned by Option 125 should be:
0x00 0x00 0x15 0xf8 0x06 0x01 0x04 0xac 0x10 0x38 0x22
Windows Server 2008 *Windows Server 2012

  1. When the switch starts and receives an IP address and Option 125 it will send a SNMP trap to the NetSight server. The NetSight server will show this newly discovered switch in OneView -> Devices -> Discovered

Additional notes
If your using Linux you will need to edit the dhcpd.cfg file.  You first need to add "option option-125 code 125 = string;" to the Server configuration section and in the PC-Client section add the DHCP option 125 coding.  The correct coding for the DHCP option is below, with "C0:A8:00:14" representing the Netsight server at IP in hex:

option option-125 00:00:15:f8:06:01:04:C0:A8:00:14;
