You can create, query, modify, and clear a unidirectional port isolation configuration.
Context
You can configure or delete the unidirectional isolation between the current interface and a specified interface. If interface A is isolated from interface B, packets sent from interface A cannot reach interface B, but packets sent from interface B can reach interface A.
NOTE: Interfaces can be isolated from one another. However, an interface cannot be isolated from itself or from the management interface unidirectionally. In addition, an Eth-Trunk cannot be isolated unidirectionally from its member interfaces.
Procedure
- Query a unidirectional isolation configuration.
- Choose in the navigation tree to display the Port Isolation page. Then click the Unidirectional Isolation tab.
- Select an interface type from the drop-down list box.
- Enter the interface number, for example, 1/0/0 (slot ID/subcard ID/interface number) .
- Click Query to display all matching records.
- Configure unidirectional port isolation.
NOTE: You can configure and modify unidirectional isolation in the same method.
- Click the corresponding
icon to open the Modify isolation port list page.
Table 1 describes the parameters on the page.
