Transparent port flooding

When the transparent port flooding feature in enabled for a interface, all MAC learning will be
disabled for that interface. This will result in all Layer 2 traffic to be flooded to all other interfaces
within the VLAN. The Transparent port flooding feature is disabled by default. To enable
Transparent port flooding, enter a command such as the following:

BigIron RX(config-if-e1000-15/8)mac-learn-disable

Syntax: [no] mac-learn-disable
