Bridge
Configura-
tion Menu
Configuring the IAD as a bridge involves several tasks. These are all
displayed and accessed on the Bridge Configuration menu (displayed by
typing 3 on the Main menu). Each task in this chapter is described
beginning at the Bridge Configuration menu.
Figure 6–2. Bridge Configuration Menu
You may sign on as Supervisor or Network Manager to configure the IAD
as a bridge. Options that display in the Bridge Configuration menu are the
same for both security levels.
Enabling
and Dis-
abling
Bridging
For bridging to function correctly, you must enable bridging both globally or
by port and then set the bridge aging timer. At least two ports must be
enabled for bridging to function. You must also disable RIP poisoned
reverse. The order in which you perform the procedures is irrelevant.
To enable routing globally (Chapter 4, Router Configuration on page 96),
you must disable bridging globally. However, you may enable routing on
some ports and bridging on others, depending on your requirements.
IP Over Bridging
IP Over Bridging is intended for use then the IAD is in full bridged mode,
but remote access (Telnet) and/or user authentication (RADIUS) are
required.

NOTE
Be sure to reset the IAD when you are done making changes
to bridge configuration. Resetting the IAD causes the
configuration changes to take effect.
NOTE
When bridging is disabled globally or on an interface (port) or
an IP address is unconfigured, IP Over Bridge is disabled
automatically.
