Ethernet Link Settings - NetModule NB3000-Line-Hd User Manual

Ethernet Link Settings

Link negotiation can be set for each Ethernet port individually. Most devices support auto-
negotiation which will con gure 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 cre-
ate virtual interfaces on top of an Ethernet interface. The VLAN protocol inserts an additional
header to Ethernet frames carrying a VLAN Identi er (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.
