• all DSL or GPON ports on the 7705 SAR-M (variants with module slots), when
a GPON, DCM, or xDSL module is installed in the chassis (qinq is not supported)
• the xDSL port on the 7705 SAR-Wx
When run on the system, ADP goes through four basic stages:
• Self-discovery
• Network Discovery
• Configuration Discovery
• Test and Commit
5.1.2.1 Self-discovery
During the self-discovery stage, all supported adapter cards and CSMs are detected
and automatically provisioned. The 7705 SAR then brings up all Ethernet ports.
Depending on the physical connectivity of the port, some ports may fail to come up.
If at least one port connected to the transport network becomes operationally up,
ADP moves to the next stage.
5.1.2.2 Network Discovery
During the network discovery stage, the 7705 SAR sends a DHCP DISCOVER
message from all operational ports. Table 16 describes the DHCP DISCOVER
message options.
Note: ADP is not supported on the 4-port SAR-H Fast Ethernet module.
Caution: In the case of an XOR port, ADP will not run successfully if the connection to the
network is made from the SFP connector because the default connector is RJ-45.
