How to check the traffic statistics of the virtual template on the NE20E?
VT is not an interface. It is a template and can be used by other service features. According to the VT, other service features generate corresponding virtual access (VA). For relative data, check the statistics of the VA.
Being a template, the VT does not serve as a reference for its statistics. Therefore, for all the services using the VT, run the display virtual-access command to check the VA information instead of running the display interface virtual-template command.
