Overriding a Forwarding Database Configuration

Overriding the Network Configuration

A Forwarding Database is used by a bridge to forward or filter packets. The bridge reads the
packet’s destination MAC address and decides to either forward the packet or drop (filter) it. If it’s
determined the destination MAC is on a different network segment, it forwards the packet to the
segment. If the destination MAC is on the same network segment, the packet is dropped (filtered).
As nodes transmit packets through the bridge, the bridge updates its forwarding database with
known MAC addresses and their locations on the network. This information is then used to decide
to filter or forward the packet.

This forwarding database assignment can be overridden as needed, but removes the device
configuration from the managed profile that may be shared with other similar device models.

To define or override a forwarding database configuration:

Select Devices from the Configuration tab.

Select Device Overrides from the Device menu to expand it into sub menu options.

Select a target device from the device browser in the lower, left-hand, side of the UI.

Select Network to expand its sub menu options.

Select Forwarding Database.

Priority

Select to enable or disable OSPF priority settings. Use the spinner to configure a value in the range
0-255. This option sets the priority of this interface becoming the Designated Router (DR) for the
network. DRs provide routing updates to the network by maintaining a complete topology table of the
network and sends the updates to the other routers in the network using multicast. Setting a high
value increases the chance of this interface becoming a DR. Setting this value to Zero (0) prevents
this interface from being elected a DR.

Cost

Select to enable or disable OSPF cost settings. Use the spinner to configure a cost value in the range
1-65535. Use this option to set the OSPF cost of this interface. OSPF cost is the overhead required to
send a packet over this interface.

Bandwidth

Select to enable or disable OSPF bandwidth settings. Use the spinner to configure a bandwidth
settings in the range 1-10,000,000 KBps. Use this option to set the bandwidth of this interface in
KBps.

Key ID

Set the unique MD5 Authentication key ID. The available key ID range is 1-255.

Password

Set the OSPF password. This value is displayed as “asterisk” (*). Select Show to display the actual
characters comprising the password.
