VLAN Examples:
Dell™ PowerEdge™ 1655MC Integrated Switch User's Guide

The following examples demonstrate typical VLAN configurations for the switch using the web interface.

Example 1 - Simple two-group VLAN setup

Example 2 - Elaborate setup

Example 1

This example steps through a simple two-group VLAN setup.

1. In the VLAN Membership page, select Add a new VLAN from the Show VLAN drop-down list.
2. In the Name box, type the symbolic name R&D to represent the new VLAN. In the VLAN ID box, type the ID value of 2 for the new VLAN. Then click Apply Changes to create the new VLAN.

3. In the VLAN Membership page, select VLAN 2 from the Show VLAN drop-down list. Because there are no ports currently in the new VLAN, all the port and trunk toggle buttons are blank. Click the toggle buttons in the Static row under the port/trunk numbers to select the desired port members of the new VLAN. Then click Apply Changes to confirm the settings.

4. Open the the VLAN, Port Settings page. To accept only tagged packets on Port 8, set Acceptable Frame Types to Tagged and enable Ingress Filtering. To allow untagged packets to be used in the new VLAN on Ports 9 and 10, change the Port VLAN IDs to VLAN 2 and leave Acceptable Frame Types set to All.

Example 2

This example steps through a more elaborate setup illustrating possible scenarios for a comprehensive understanding of tagged VLANs.

1. Set up VLANs as shown in the table below:

VLAN ID	Name	Port Members (Tagged/Untagged)
1	Default	1 (U), 2 (U)
5	Internal	1 (U), 4 (U), 5 (U)
10	Web	1 (T), 9 (T), 10 (T), 11 (U)
15	Collocation	1 (U), 2 (U)

2. Set up the Port VLAN IDs as shown in the following illustration:

The VLANs set up in the preceding procedure produce results as follows:

If an untagged packet enters Port 4, the switch tags it with a VLAN tag value of 1. Since Port 4 does not have membership with VLAN ID 1, the default, the system drops the packet.
If a tagged packet with a VLAN tag value 5 enters Port 4, the packet has access to Ports 1 and 5. If the packet leaves Port 1 and/or 5, it is stripped of its tag as it leaves the switch and becomes an untagged packet.
If a tagged packet with a VLAN tag value 10 enters Port 9, it has access to Ports 1, 10, and 11. If the packets leave Port 1 or 10, they are tagged with a VLAN ID value of 10. If the packet leaves Port 11, it leaves as an untagged packet.
If a tagged packet with a VLAN tag value 1 enters Port 9, it is dropped since Port 9 has ingress filtering enabled and will drop any packets that are not tagged with VLAN ID 10.
