It lists the available and grouped interfaces. Follow the instructions shown

onscreen.

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

ENET1, ENET2, ENET3, and ENET4.

The Interface Grouping configuration will be:

1. Default: ENET1, ENET2, ENET3, and ENET4.

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 ENET1 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: ENET2, ENET3, and ENET4

2. Video: nas_0_36, nas_0_37, nas_0_38, and ENET1.
