Port isolation configuration example
Configuring port isolation
The port isolation feature isolates Layer 2 traffic for data privacy and security without using VLANs. You can also use this feature to isolate the hosts in a VLAN from one another.
You can manually create isolation groups on the switch, but only the isolation group numbered 1 is valid. The number of ports assigned to an isolation group is not limited.
Within the same VLAN, ports in an isolation group can communicate with those outside the isolation group at Layer 2.
Assigning ports 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 |
For this switch series, only the isolation group numbered 1 is valid. |
|
3. Enter interface view. |
·
Enter Layer 2 Ethernet interface view: ·
Enter Layer 2 aggregate interface view: |
· 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 ports to the specified isolation group. |
port-isolate enable group group-number |
No ports are assigned to an isolation group by default. For this switch series, you can assign ports to only isolation group 1. |

Port isolation configuration example
Network requirements
As shown in Figure 1, LAN users Host A, Host B, and Host C are connected to FortyGigE 1/0/1, FortyGigE 1/0/2, and FortyGigE 1/0/3 on the device, respectively. The device connects to the Internet through FortyGigE 1/0/4.
Configure the device to provide Internet access for the hosts, and isolate them from one another at Layer 2.
Configuration procedure
# Create isolation group 1.
<Device> system-view
[Device] port-isolate group 1
# Assign FortyGigE 1/0/1, FortyGigE 1/0/2, and FortyGigE 1/0/3 to isolation group 1.
[Device] interface fortygige 1/0/1
[Device-FortyGigE1/0/1] port-isolate enable group 1
[Device-FortyGigE1/0/1] quit
[Device] interface fortygige 1/0/2
[Device-FortyGigE1/0/2] port-isolate enable group 1
[Device-FortyGigE1/0/2] quit
[Device] interface fortygige 1/0/3
[Device-FortyGigE1/0/3] port-isolate enable group 1
Verifying the configuration
# Display information about isolation group 1.
[Device-FortyGigE1/0/3] display port-isolate group 1
Port isolation group information:
Group ID: 1
Group members:
FortyGigE1/0/1
FortyGigE1/0/2
FortyGigE1/0/3
