Static Entry for MAC Addresses of End Users with Multiple
ELAN/VLAN Mappings
The MAC Address for any end device which has multiple ELAN/VLAN
mappings must be entered in the Add Router MAC screen of every
BRIM-A6DP present on the network except for the BRIM-A6DP that is
installed in the host device to which the end user is directly connected.
For information on how to complete this procedure, refer to Section 3.12.
Shared Media is Not Supported
ELAN/VLAN mappings are not able to be maintained across shared
media such as Token Ring and FDDI.
Multiple VLAN Registration
If an Ethernet port is mapped to more than one VLAN, that Ethernet port
must not be connected to another Ethernet switch, repeater, bridge, or
router. Only end users are allowed on an Ethernet port that is registered to
more than one VLAN. The MAC Address for any end device which has
multiple ELAN/VLAN mappings must be entered in the Add Router
MAC screen of every BRIM-A6DP present on the network except for the
BRIM-A6DP that is installed in the host device to which the end user is
directly connected. For information on how to complete this procedure,
refer to Section 3.12.
Deletion of LEC Instances
If a LEC is deleted by the user, all Ethernet ports that were mapped to that
LEC instance are no longer able to communicate with the ATM network.
The Ethernet ports must be reassigned to another VLAN which contains
another LEC instance to reestablish communication with the ATM
network.
