If you want to delete the mirroring configuration after using the mirroring function, you can perform the following operations:

1. Run the display current-configuration command to check the current mirroring configuration. For example, you can view the following mirroring configuration.

   <HUAWEI> display current-configuration
   #
   vlan batch 10 20 30
   #
   observe-port 2 interface GigabitEthernet0/0/1
                ...
                ...
   #
   interface GigabitEthernet0/0/1
   #
   interface GigabitEthernet0/0/2
                ...
                ...
   #
   interface GigabitEthernet0/0/10
     port-mirroring to observe-port 2 inbound
   #
                ...
                ...

2. Run the undo port-mirroring command on the mirrored port to delete the binding between the observing port and mirrored port and restore the mirrored port as a common port. For example, restore GE0/0/10 in step 1 to a common port.

   <HUAWEI> system-view
   [HUAWEI] interface gigabitethernet 0/0/10
   [HUAWEI-GigabitEthernet0/0/10] undo port-mirroring to observe-port 2 inbound
   [HUAWEI-GigabitEthernet0/0/10] quit

3. Run the undo observe-port command in the system view to delete the observing port. For example, delete the observing port in step 1 and restore GE0/0/1 to a common port.

   [HUAWEI] undo observe-port 2

   You can delete the observing port only after deleting the binding between the observing port and mirrored port.
