Description:

Four networks are to be separated from each other by means of ARF and VLAN tags. The clients are to be allocated to the relevant network according to the switch port they use.


Requirement:
  • LANCOM managed switch of type LANCOM GS-23XX(P)
  • A LANCOM router that can address at least 4 networks using ARF. This example uses a LANCOM 1781A.


Scenario:


Setup:

LANCOM 1781A with 4 ARF networks in different VLANs:

Network name IP address Netmask VLAN ID
VLAN-1 (INTRANET) 192.168.10.35 255.255.255.0 1
VLAN-2 192.168.2.1 255.255.255.0 2
VLAN-3 192.168.3.1 255.255.255.0 3
VLAN-4 192.168.4.1 255.255.255.0 4

The LANCOM 1781A is connected via ETH port 1 to port 10 of the LANCOM GS-23XX(P) and is a member of all VLANs.


Objective:
  • Workstations connected to port 1 of the LANCOM GS-23XX(P) are to be given VLAN tag (1) and become members of the ARF network (INTRANET).
  • Workstations connected to ports 2 and 3 of the LANCOM GS-23XX(P) are to be given VLAN tag (2) and become members of the ARF network (VLAN-2).
  • Workstations connected to ports 4 and 5 of the LANCOM GS-23XX(P) are to be given VLAN tag (3) and become members of the ARF network (VLAN-3).
  • Workstations connected to ports 6 and 7 of the LANCOM GS-23XX(P) are to be given VLAN tag (4) and become members of the ARF network (VLAN-4).

Firewall rules, interface tags and routing tags can be used to set further restrictions on the data traffic (see ).



Procedure:

1) Configuring the LANCOM 1781A:

Create the ARF networks as defined by a VLAN-ID under IPv4 -> General -> IP networks:



2) Configuring the LANCOM GS-23XX(P):

2.1) Create the individual VLANs under VLAN -> VLAN Membership and activate the ports that are to belong to each VLAN:
  • VLAN-1: VLAN-ID 1 / ports 1 and 10
  • VLAN-2: VLAN-ID 2 / ports 2, 3 and 10
  • VLAN-3: VLAN-ID 3 / ports 4, 5 and 10
  • VLAN-4: VLAN-ID 4 / ports 6, 7 and 10

2.3) Click on Apply to save the configuration.



2.4) Switch to menu VLAN -> Ports and assign the relevant VLAN IDs (PVID) to the appropriate ports.
  • Port 1: PVID 1
  • Ports 2 & 3: PVID 2
  • Ports 4 & 5: PVID 3
  • Ports 6 & 7: PVID 4
  • Port 10: PVID 1



2.5) Click on Apply to save the configuration.

2.6) Check the configuration by connecting to each port on the switch. An IP address from the corresponding network will be assigned.
