5.14 Interface Grouping Interface Grouping supports multiple ports to PVC and bridging groups. Each group performs as an independent network. To use this feature, you must create mapping groups with appropriate LAN and WAN interfaces using the Add button. The Remove button removes mapping groups, returning the ungrouped interfaces to the Default group. Only the default group has an IP interface. To add an Interface Group, click the Add button. The following screen will appear.
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).
