== Dual EMAC mode (NaonEVB-Lite)==

The two Ethernet interfaces on [[Category:NaonEVB-Lite|NaonEVB-Lite]] can be used as:
* Ethernet switch: Linux sees only one Ethernet interface and packets are routed between the two ports like a standard Ethernet switch does.
* Dual EMAC Mode: Linux sees two independent Ethernet interfaces and packet are routed between the two like a Ethernet router does.

The default configuration provided with [[Naon Embedded Linux Kit (NELK)]] is ''Dual EMAC Mode'', where ''eth0'' is the [[Category:Naon|Naon]] on-board 10/100Mbit Ethernet interface, while eth1 is the  [[Category:NaonEVB-Lite|NaonEVB-Lite]] Gigabit interface.

The official TI documentation to enable and use Dual EMAC is [http://processors.wiki.ti.com/index.php/DM814x_AM387x_Ethernet_Switch_User_Guide#Dual_Standalone_EMAC_mode here]

Please note that no routing is enabled between the two interface is Dual EMAC mode by default. Linux userspace tool should be used to configure VLAN tagging and packet routing rules.
