•
Automatically Add Location Element for this VLAN - Checked by default.
Automatically create/edit a Location when the VLAN itself is changed. If a Location
does not exist, the Location is created with this VLAN ID, using the same name as the
Managed VLAN. If a matching Location exists with the original VLAN ID, a new
Location is not created; instead, the VLAN ID is updated to this VLAN ID.
If the BSC is a Replication Node, the checkbox is disabled, because the BSC uses
Locations, not the interfaces themselves, to support separate network topologies
within a replication matrix. Changes to locations cannot break replication and should
be propagated on a master.
The remaining managed-side VLAN parameter settings are common to the managed

physical interface. Configure these parameters as described in the previous sections
starting in "Configuring Wireless Client IP Address Assignment" on page 4-9. You
must enable multicast on the Managed Interface if you have one or more managed
VLANs that use multicast.
Click Save to save the managed-side VLAN settings to the BSC database or Save and

create another to continue creating managed-side VLANs.
You might be prompted to restart the BSC. We recommend that you do not restart the
BSC until you have completely finished configuring the BSC for use in your network.

Configuring a Managed Remote Subnet

In most BSC configurations, the wireless network is directly connected to either the
physical or VLAN interface on the managed side. However, in some cases, the wireless
network is not directly connected to the interface but instead is only accessible across a
routed network.
For example, it might be more cost-effective in some public access environments to route
several small wireless LANs back through a WAN to a centrally located BSC, rather than
install a BSC at each wireless LAN site.
In this network configuration, known as a managed remote subnet, the local wireless
subnet employs a router that is configured for DHCP relay, forwarding "IP Helper", etc.
The BSC will use DHCP to hand out IP addresses to clients on the remote wireless
networks. The following figure illustrates a managed-side remote subnet.
To set up a managed remote subnet:
Click the Network tab, and then click the Managed tab.
