Automatic Discovery Protocol

Automatic Discovery Protocol (ADP) is triggered by a factory-installed boot option and automates the initial commissioning of 7705 SAR nodes. When the 7705 SAR is started for the first time, an ADP keyword in the BOF causes automatic discovery to run as part of the TiMOS application image. Refer to the appropriate chassis installation guide, ‟Automatic Discovery Protocol”, for more information on ADP.

ADP supports null, dot1q, and qinq encapsulation on:

• all ports on the 6-port Ethernet 10Gbps Adapter card

• all ports on the 8-port Gigabit Ethernet Adapter card

• all ports on the 10-port 1GigE/1-port 10GigE X-Adapter card (supported on the 7705 SAR-18 only)

• all ports on the 6-port SAR-M Ethernet module

• all Ethernet ports on the 7705 SAR-A, 7705 SAR-Ax, 7705 SAR-H, 7705 SAR-Hc, 7705 SAR-Wx, and 7705 SAR-X

When run on the system, ADP goes through four basic stages:

• Self-discovery

• Network Discovery

• Configuration Discovery

• Test and Commit
