Bridge Configuration

The bridge subsystem allows you to configure and monitor the bridging and port-based VLAN functions of the AES-100.

The AES-100 supports IEEE 802.1d transparent bridging; but not the static filtering feature or spanning tree protocol. The bridge learns the source MAC addresses of sender hosts by inspecting incoming Ethernet frames and recording the learned MAC addresses with their incoming port numbers into its filtering database. Based on the database, the bridge forwards each incoming frame to its destination port.

6.1Bridge Port Numbers

The bridge subsystem of the AES-100 defines its own numbering convention for ports. The bridge has a total of nine ports; bridge port 1 stands for Ethernet port, bridge port 2 stands for ADSL port 1, bridge port 3 stands for ADSL port 2, and so on. Be sure you have clarified the relation between bridge ports and ADSL ports.

6.2Port-Based VLAN

The VLAN (Virtual LAN) mechanism can be used to limit the broadcast domain to the members of a VLAN group only. Users of one group are not allowed to access the resources of other groups and a higher level of security is achieved.

The AES-100 supports port-based VLAN, one type of VLAN implementation. Port-based VLAN requires each incoming port to define its allowed outgoing ports. Ethernet frames are forwarded according to these rules.

6.2.1Default Settings of Port-Based VLAN

The factory default settings for the port-based VLAN of the AES-100 are:

-Bridge port 1 (Ethernet port) allowed to all bridge ports

-Bridge port 2 (ADSL port 1) allowed to bridge port 1 (Ethernet port) only

-Bridge port 3 (ADSL port 2) allowed to bridge port 1 (Ethernet port) only

-Bridge port 4 (ADSL port 3) allowed to bridge port 1 (Ethernet port) only

-Bridge port 5 (ADSL port 4) allowed to bridge port 1 (Ethernet port) only

-Bridge port 6 (ADSL port 5) allowed to bridge port 1 (Ethernet port) only

-Bridge port 7 (ADSL port 6) allowed to bridge port 1 (Ethernet port) only

-Bridge port 8 (ADSL port 7) allowed to bridge port 1 (Ethernet port) only
