Hi, friend!
By default, the device supports only the local mirroring function, but does not support the remote mirroring function. (including Layer 2 remote mirroring RSPAN and Layer 3 remote mirroring ERSPAN) To enable the remote mirroring function, the plug-in of the corresponding version must be installed on the device. Log in to Huawei enterprise technical support website or Huawei carrier technical support website to obtain the corresponding plug-in and Plug-in User Guide. If the plug-in is not installed, you are advised to install it first.
