Automatically Add Clients With Following DHCP Vendor IDs:
Add support to automatically map LAN interfaces to PVC's using
DHCP vendor ID (option 60). The local DHCP server will decline
and send the requests to a remote DHCP server by mapping the
appropriate LAN interface. This will be turned on when Interface
Grouping is enabled.
For example, imagine there are 4 PVCs (0/33, 0/36, 0/37, 0/38). VPI/
VCI=0/33 is for PPPoE while the other PVCs are for IP set-top box
(video). The LAN interfaces are LAN1, LAN2, LAN3, and LAN4.
The Interface Grouping configuration will be:
1. Default: LAN1, LAN2, LAN3, and LAN4.
2. Video: nas_0_36, nas_0_37, and nas_0_38. The DHCP vendor
ID is "Video".
If the onboard DHCP server is running on "Default" and the
remote DHCP server is running on PVC 0/36 (i.e. for set-top box
use only). LAN side clients can get IP addresses from the CPE's
DHCP server and access the Internet via PPPoE (0/33).
If a set-top box is connected to ETH1 and sends a DHCP request
with vendor ID "Video", the local DHCP server will forward this
request to the remote DHCP server. The Interface Grouping
configuration will automatically change to the following:
1. Default: LAN2, LAN3, and LAN4
2. Video: nas_0_36, nas_0_37, nas_0_38, and LAN1
