Appendix G - Dhcp Server Requirements - Black Box iPATH ACR1000A-CTL-24 User Manual

APPENDIX G - DHCP SERVER REQUIREMENTS

Version 1.0
G.1 AGILITY DHCP CLIENT
The Agility DHCP client will identify itself to a DHCP server using DHCP option 60 (Vendor-Class-Identifier) containing the brand
string appropriate to the firmware.
The Agility DHCP client will also provide the DHCP server with its unique hostname and a request for DHCP option 125 (Vendor
Identified Vendor Sub Options). See
G.2 DHCP SERVER
A DHCP server will use the Vendor-Class-Identifier to identify an Agility and supply it with vendor information encapsulated in the
Enterprise number (25119) within DHCP option 125 (Vendor Identified Vendor Sub Options).
As of Agility firmware version 4.2, the required vendor information to be encapsulated is:
Sub-option 1: Array of IP addresses of all iPATH servers in the cluster.
Note: Agility will ignore any DHCP OFFER not containing this information.
