The latter configures a port to permit packets from only one isolate-user-VLAN to pass through.

Configuration procedure

To configure an isolate-user-VLAN, complete the following tasks:

1.

Configure the isolate-user-VLAN.

2.

Configure the secondary VLANs.

3.

Associate the isolate-user-VLAN with the specified secondary VLANs.

4.

Configure uplink and downlink ports in the following workflow:

a.

Configure the uplink ports, for example, the port connecting Device B to Device A in

Figure 41

,

to operate in promiscuous mode in the specified VLAN, so that uplink ports can be

automatically added to the specified isolate-user-VLAN and the secondary VLANs associated

with the isolate-user-VLAN.

b.

Configure the downlink ports, for example, the ports connecting Device B to hosts in

Figure 41

,

to operate in host mode, so that downlink ports can be automatically added to the

isolate-user-VLAN associated with the secondary VLAN.
For more information about the promiscuous and host mode commands, see Layer 2—LAN

Switching Command Reference.

To configure an isolate-user-VLAN:

6.

Configure Layer 2 isolation
between ports in the same

secondary VLAN.

isolated-vlan enable

Optional.
By default, ports in the same
secondary VLAN can

communicate with one another at

Layer 2.
This configuration takes effect only
after you configure all ports in the

same secondary VLAN to operate

in host mode and associate
secondary VLANs with an

isolate-user-VLAN.

8.

Associate the

isolate-user-VLAN with the
specified secondary VLANs.
