Inter-slot traffic statistics failure on an aggregate interface
Symptom
Network connections and interface IPoE configurations are correct and traffic statistics can be performed correctly for an aggregate interface with member ports on different slots. Traffic statistics fails after the member port on the initially accessed slot goes down and the user accesses the member port on another slot.
Analysis
Traffic statistics is performed on the slot that the user initially accessed. When a member port on the initially accessed slot becomes down, the user traffic is redirected to the member port on another slot. If no traffic exists on the initially accesses slot, traffic statistics cannot be performed.
Solution
Use the service command to specify a service slot for traffic statistics. Traffic will be forwarded to the specified service card for statistics.
To avoid interrupting traffic statistics, make sure the specified service slot is present.
