This article describes how VLAN is configured on a GS-3xxx series switch.
...
| Info |
|---|
Please note how the different VLAN tagging modes work. |
Requirements:
- LANCOM switch of the GS-3xxx series
- LANCOM router capable of managing at least three ARF networks
- LCOS as of version 8.50 (download latest version)
- LANtools as of version 8.50 (download latest version)
- Any web browser for accessing the web interface of the GS-3xxx
...
- Port 1:
- Mode: Select the tagging mode Hybrid, as the router is also set to Hybrid (see Scenario).
- Port VLAN: Enter the VLAN ID 1 because the network INTRANET (VLAN ID 1) acts as a management network.
- Ingress Acceptance: Select Tagged and Untagged from the drop-down menu, because when using the Hybrid tagging mode, both tagged and untagged packets are allowed.
- Egress Tagging: Select Untag Port VLAN. When using the Hybrid tagging mode, the VLAN tag is removed from outbound packets that have the port VLAN ID (in this case VLAN ID 1).
- Allowed VLANs: Enter VLANs 1 - 3, because all VLANs created on the router are to be transmitted.
- Port 2:
- Mode: Select the tagging mode Trunk, as the other switch is also set to Trunk (see Scenario).
- Port VLAN: The VLAN ID can be left at the value 1. When using the Trunk tagging mode, the Port VLAN ID not used.
- Ingress Acceptance: Select Tagged Only from the drop-down menu, because when using the Trunk tagging mode, only tagged inbound packets are allowed.
- Egress Tagging: Select Tag All. When using the Trunk tagging mode, only tagged outbound packets are sent.
- Allowed VLANs: Enter VLANs 1 - 3, because all VLANs created on the router are to be transmitted to the other switch.
- Port 3:
- Mode: Select the tagging mode Access, because an end device that does not support VLAN is to be connected.
- Port VLAN: Enter the VLAN ID 1 because access to the INTRANET network requires the VLAN ID 1.
- Ingress Acceptance: When using the Access tagging mode, this setting is grayed out and cannot be changed.
- Egress Tagging: When using the Access tagging mode, this setting is grayed out and cannot be changed.
- Allowed VLANs: When using the Access tagging mode, this setting is grayed out and cannot be changed. The Port VLAN ID is entered automatically.
- Port 4:
- Mode: Select the tagging mode Access, because an end device that does not support VLAN is to be connected.
- Port VLAN: Enter the VLAN ID 2 because access to the PRODUCTION network requires the VLAN ID 2.
- Ingress Acceptance: When using the Access tagging mode, this setting is grayed out and cannot be changed.
- Egress Tagging: When using the Access tagging mode, this setting is grayed out and cannot be changed.
- Allowed VLANs: When using the Access tagging mode, this setting is grayed out and cannot be changed. The Port VLAN ID is entered automatically.
- Port 5:
- Mode: Select the tagging mode Access, because an end device that does not support VLAN is to be connected.
- Port VLAN: Enter the VLAN ID 3 because access to the GUEST NETWORK requires the VLAN ID 3.
- Ingress Acceptance: When using the Access tagging mode, this setting is grayed out and cannot be changed.
- Egress Tagging: When using the Access tagging mode, this setting is grayed out and cannot be changed.
- Allowed VLANs: When using the Access tagging mode, this setting is grayed out and cannot be changed. The Port VLAN ID is entered automatically.

In the case of Allowed VLANs, you can also specify non-contiguous ports by separating them with a comma (e.g. 1,3,5). You can also specify contiguous and non-contiguous ports in the same entry (e.g. 1,3,5-10). |
| Hinweis |
|---|
In the case of Allowed VLANs only the VLANs actually used must be entered, as otherwise this can lead to a dramatically increased CPU load of the switch. |
3) In the field Allowed Access VLANs enter all VLAN-IDs, which are used by ports with the tagging mode Access (in this example the VLAN-IDs 1-3).

In the case of Allowed Access VLANs only VLAN IDs which are assigned to a port with the tagging mode Access must be entered, as otherwise this can lead to a dramatically increased CPU load of the switch. |
4) After completing the VLAN configuration, click Apply to keep the changes.
...
5) Change to the menu Maintenance → Configuration → Save Startup-config. Under File name, select the startup-config item and click on Save Configuration to set this configuration as the start configuration.
...

After restarting the switch, the start configuration is always loaded. If none is available, the default configuration will be loaded and the switch starts in its factory state. |
