Option-60 DHCP Option 60 is used by the Switch for identification to the DHCP server using the VCI
(Vendor Class Identifier) on the DHCP server. The Switch adds it in the initial DHCP discovery
message that a DHCP client broadcasts in search of an IP address. The DHCP server can assign
different IP addresses or options to clients with the specific VCI or reject the request from clients
without the specific VCI.
Select this and enter the device identity you want the Switch to add in the DHCP discovery
frames that go to the DHCP server. This allows the Switch to identify itself to the DHCP server.
Class-ID Type a string of up to 32 characters to identify this Switch to the DHCP server. For example, Zyxel-
TW.
