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. However, 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.
