Parameter | Description | |
|
|
|
Flood | Specify the Flood setting. Flood refers to the | |
| method in which interface modules handle | |
| unknown unicasts (traffic directed to a single | |
| MAC Address), broadcasts (traffic directed to all | |
| MAC Addresses) and multicasts (traffic directed | |
| to multiple MAC Addresses) for each port. | |
| z Upl (Uplink) – Unknown unicast, broadcast | |
| and multicast traffic is flooded only to the | |
| DSLAM uplink interface ports. This prevents | |
| communication between interface ports | |
| without the intervention of an upstream | |
| device such as a router. If communication | |
| between interface ports is desired, the | |
| upstream device must be properly configured | |
| to allow it. | |
| z Vln (VLAN) – Unknown unicast, broadcast | |
| and multicast traffic is flooded to the | |
| DSLAM’s ADSL ports (within the sender's | |
| VLAN range) in addition to the uplink | |
| interface ports. | |
|
|
|
Ethertype | Specify the Ethertype of the backbone tag added | |
| to traffic if the backbone VLAN ID is | |
| configured. Used only in conjunction with | |
| backbone VLANs. | |
