address
Note: If the BSC managed IP subnet is different from the protected IP subnet and NAT is
not enabled, then you must configure static routes on your network routers to reach the
managed network. These static routes would point to the BSC's protected interface as
their next "hop."
See "Configuring the BSC to Assign Fixed IP Addresses" on page 4-14 for information
about mapping an individual wireless client IP address to a specific device IP address on
the protected side.
Enable multicast
Mark this checkbox to enable use of distance vector multicast routing protocol (DVMRP or
for this interface
PIM-SM) for this interface.
Force proxy ARP
Mark this checkbox to enable the BSC to force proxy address resolution protocol (ARP)
for this interface
for traffic directed to clients behind the protected interface.
You should enable this option only when the protected interface and the managed
interface reside within the same IP subnet. If this checkbox is cleared, the BSC determines
whether the network setup requires proxy ARP.
Port settings
By default, the BSC's physical interfaces automatically negotiate bit rate and duplex type
for connections. However, if required, you can specify interface speed and duplex type
here. Max indicates the highest speed supported by an interface (for example, the BSC-
2100 protected interface supports a speed of1000 Mbps maximum).
Display
Specify which login page to display to users logging into the BSC on the managed
interface—the default user login page or a customized page you have defined. See
"Customizing the User Login Page" on page 11-2 for information about creating a
customized user login page.
