4.3 VLAN/ELAN Mapping
The ATM Module allows VLANs created on the switch to be extended out the
ATM interface to an ELAN where the ES-2810 acts as a proxy LEC device. The
ES-2810 supports port-based and MAC address-based VLAN assignment.
The switch is pre-configured with a VLAN named
system
as the first VLAN in-
stance. A corresponding ELAN named
default
also exists. When an ATM Mod-
ule is installed in the switch, it will become a part of the
system
VLAN and will
automatically attempt to join the
default
ELAN, and begin bridging traffic. The
ELAN name cannot be changed since it is confined by the VLAN name. To change
the name, delete the VLAN and re-create it before mapping it to an ELAN.
You can use FORE Stack View (FSV) to do the following:
• Create VLANs (see the ES-2810 Ethernet Switch User Manual)
• Map VLANs to ELANs on the ATM network (see Section 4.3.1)
• Enable Spanning Tree Protocol per VLAN (see Section 4.3.2)
4.3.1 Mapping VLANs to ELANs
The ES-2810 supports up to 16 VLANs on the Ethernet LAN which can be mapped
to ELANs on the ATM network. Figure 8 shows an example of VLANs mapped to
ELANs.
