Configuring port isolation
The port isolation feature isolates Layer 2 traffic for data privacy and security without using VLANs.
Ports in an isolation group cannot communicate with each other, but they can communicate with ports
outside the isolation group.
Assigning a port to an isolation group
The device supports multiple isolation groups, which can be configured manually. The number of ports
assigned to an isolation group is not limited.
To assign a port to an isolation group:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Create an isolation
group.
port-isolate group
group-number
By default, no isolation group exists.
3.
Enter interface view.
•
Enter Layer 2 Ethernet
interface view:
interface
interface-type
interface-number
•
Enter Layer 2 aggregate
interface view:
interface bridge-aggregation
interface-number
•
The configuration in Layer 2 Ethernet
interface view applies only to the
interface.
•
The configuration in Layer 2 aggregate
interface view applies to the Layer 2
aggregate interface and its
aggregation member ports. If the
device fails to apply the configuration
to the aggregate interface, it does not
assign any aggregation member port
to the isolation group. If the failure
occurs on an aggregation member
port, the device skips the port and
continues to assign other aggregation
member ports to the isolation group.
4.
Assign the port to the
specified isolation
group.
port-isolate enable group
group-number
By default, the port is not in any isolation
group.
You can assign a port to at most one
isolation group. If you execute the
port-isolate enable group
command
multiple times, the most recent
configuration takes effect.
