Isolate-user-VLAN configuration

Overview

An isolate-user-VLAN uses a two-tier VLAN structure. In this approach, the following types of VLANs,
isolate-user-VLAN and secondary VLAN, are configured on the same device.
The following are the characteristics of the isolate-user-VLAN implementation:
Isolate-user-VLANs are mainly used for upstream data exchange. An isolate-user-VLAN can be
•
associated with multiple secondary VLANs. As the upstream device identifies only the
isolate-user-VLAN and not the secondary VLANs, network configuration is simplified and VLAN
resources are saved.
• You can isolate the Layer 2 traffic of different users by assigning the ports connected to them to
different secondary VLANs. To enable communication between secondary VLANs associated with
the same isolate-user-VLAN, you can enable local proxy ARP on the upstream device (for example,
Device A in Figure 46) to realize Layer 3 communication between the secondary VLANs.
As shown in
isolate-user-VLAN. VLAN 2, VLAN 5, and VLAN 8 are secondary VLANs associated with VLAN 10 and
are invisible to Device A.

Configuring an isolate-user-VLAN

To configure an isolate-user-VLAN, complete the following tasks:
Configure the isolate-user-VLAN.
1.
Configure the secondary VLANs.
2.
Configure uplink and downlink ports:
3.
Configure the uplink ports, for example, the port connecting Device B to Device A in
to work in promiscuous mode in the specified VLAN, so that the uplink ports can be added to
the specified isolate-user-VLAN and the secondary VLANs associated with the
isolate-user-VLAN synchronously.
Figure 46, the isolate-user-VLAN function is enabled on Device B. VLAN 10 is the
