Syntax: show port security global-deny
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
Displaying transparent port flooding status
To display if the transparent port flooding feature has been enabled, issue the show interface
ethernet <interface> or show running-configuration command.
