Isolate-user-VLAN can save the VLAN resource in a network. It adopts the
two-level VLAN architecture. One level is isolate-user-VLAN level, and the other is
Secondary VLAN level, as shown in Figure 12.
An isolate-user-VLAN corresponds to multiple Secondary VLANs. It contains all
■
the ports and upstream ports of the corresponding Secondary VLANs. In this
way, a switch that is of upper level only needs recognizing the
isolate-user-VLANs of the downstream switch instead of the Secondary VLANs,
thereby streamlining the configuration and saving the VLAN source.
You can use isolate-user-VLAN to implement the isolation of the Layer-2
■
packets by assigning a Secondary VLAN for each user, with each of the
Secondary VLANs containing the ports and the upstream ports connected to
the user. You can configure the ports connected to different users to be of the
same Secondary VLAN to enable these users to communicate with each other
on Layer 2.
