Allocation of MAC addresses to the DSL ports

If a LANCOM uses switch ports to gain access to multiple DSL (WAN) interfaces, an appropriate number of MAC addresses must be used to differentiate the DSL ports. As there are cases where the required MAC address depends upon the remote site which, for example, uses the MAC address to determine the DSL access charge, the MAC addresses are defined for the logical DSL remote sites and not for the physical DSL ports.

The following options are available for setting the MAC address:

Global: Global system MAC address
Local: The unique, locally managed MAC address is calculated from the global address
User defined: A MAC address that can be freely defined by the user

Note: Every DSL connection contains its own MAC address. If two remote stations are configured with identical MAC addresses, the first connection uses the configured MAC address. For the second connection a "locally managed", unambiguous MAC address will be calculated from the user-defined MAC address.

When using channel bundling, the configured MAC address is used for the first connection, for all other bundle connections the locally managed MAC addresses based on the user-defined MAC address will be calculated.

If one of your connections is charged via the MAC address, configure this MAC address for the separately charged connection only. For all other connections you should use another address.
