VLAN Management
M!DGE/MG102i routers support Virtual LAN according to IEEE 802.1Q which can be used to create
virtual interfaces on top of the 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. In order to form a distinctive subnet, the network interface of a remote
LAN host must be configured with the same VLAN ID as defined on the router. Further, 802.1P introduces
a priority field which influences packet scheduling in the TCP/IP stack.
The following priority levels (from the lowest to the highest) exist:
VLAN Priority Levels Parameter
Background 0
Best Effort 1
Excellent Effort 2
Critical Applications 3
Video (< 100 ms latency and jitter) 4
Voice (< 10 ms latency and jitter) 5
Internetwork Control 6
Network Control 7
IP Settings
Two individual tabs will be used when different LANs are set in the Port settings menu. Each of them
can be configured either in the LAN mode or in the WAN mode.
Note
The default IP addresses are as follows: 192.168.1.1/24 (LAN1) and 192.168.2.1/24 (LAN2).
