Default Value

This testvar’s default value is computed dynamically and may not always be the value below. Please see the testvar’s description for details.


This parameter specifies the ACS URL that the DHCP server will announce in the Vendor Specific Information (DHCPv4 option 43 / DHCPv4 option 125 / DHCPv6 option 17) when the string “” (all lower case) is detected anywhere in the DHCPv4 Vendor Class Identifier (option 60), in the DHCPv4 V-I Vendor Class Option (option 124) or in a DHCPv6 Vendor Class (option 16) vendor-class-data item.

If not specified, the ACS will build a URL using a combination of acsTransport, acsDomain, and acsPort (acsTransport://acsDomain:acsPort/). This testvar can be used to override the default behavior and use DNS names if desired. Set this testvar to ’none’ to disable ACS URL discovery completely.
