You have a two-interface bridge and want to enable link error propagation, or you want to propagate errors on a LAN bridge interface to WAN bridge interface and vice versa.
Some ProxySG appliances ship (when ordered) with a network adapter card that can be used as a pass-through adapter or as a Network Interface Card (NIC), depending on the configured mode. If the network adapter mode is set to disabled, the adapter interfaces can be used as NICs or as part of a software bridge.
If your appliance includes a programmable adapter card, the following programmable adapter modes are available:
Disabled—Disables the bridge and allows the adapter interfaces to be reused as NICs or as part of another bridge.
Fail Open—If the ProxySG fails, all traffic passes through the bridge so clients can still receive data.
Fail Closed—If the ProxySG fails, all traffic is blocked and service is interrupted. This mode provides the same functionality as a user-configured software bridge.
The following procedure describes programmable adapter configuration.
To configure the function of the programmable adapter:
