Chapter 1  Port Isolation Configuration

1.1  Port Isolation Overview

1.1.1  Introduction to Port Isolation

Through the port isolation feature, you can add the ports to be controlled into an isolation group to isolate the Layer 2 and Layer 3 data between each port in the isolation group. Thus, you can improve the network security and network in a more flexible way.

Currently, you can configure 64 isolation groups on a switch. The number of Ethernet ports an isolation group can accommodate is not limited.

 

 

1.1.2  Port Isolation and Link Aggregation

When a member port in an aggregation group joins an isolation group, the other ports in the aggregation group joins the isolation group automatically.

1.2  Port Isolation Configuration

Table 1-1 lists the operations to add an Ethernet port to an isolation group to isolate Layer 2 data between each port in the isolation group.

Table 1-1 Configure port isolation

Operation	Command	Description
Enter system view	system-view	—
Create an isolation group	port-isolate group group-id	Required
Specify a description string for the isolation group	description text	Optional
Add the specified port into the isolation group	port interface-list	Optional By default, an isolation group contains no Ethernet port.
Enter Ethernet port view	interface interface-type interface-number	—
Add the current Ethernet port to the isolation group	port isolate group group-id	Required By default, an isolation group contains no Ethernet port.

 

 

1.3  Displaying Port Isolation Configuration

After the above configuration, you can execute the display command in any view to view the information about the Ethernet ports added to the isolation group.
