Figure 5.7.: Ethernet Link Settings
Link negotiation can be set for each Ethernet port individually. Most devices support auto-negotiation
which will configure the link speed automatically to comply with other devices in the network. In case
of negotiation problems, you may assign the modes manually but it has to be ensured that all devices
in the network utilize the same settings then.
VLAN Management
NetModule routers support Virtual LAN according to IEEE 802.1Q which can be used to create virtual
interfaces on top of an Ethernet interface. The VLAN protocol inserts an additional header to Ethernet
frames carrying a VLAN Identifier (VLAN ID) which is used for distributing the packets to the associated
virtual interface. Any untagged packets, as well as packets with an unassigned ID, will be distributed
to the native interface.
