How to Configure the Constant Interface Index Feature on Huawei S2700?

Questions: 
How to configure the Huawei OLT Constant Interface Index Feature on Huawei Quidway S2700?

Answer: 
Procedure
Run:system-view,The system view is displayed.
Run:ifindex constant,The constant interface index feature is enabled.After the feature is enabled, the indexes for all the existing interfaces and newly created interfaces are fixed. If the system needs to restart, the save command must be run to save interface configurations; otherwise, the interface indexes will change after the system is restarted.
Run:set constant-ifindex max-number number,The maximum number of interfaces indexed by fixed numbers is set.
If interfaces are frequently added or deleted during system operation, the interface index file stored in the device may have a great size and consume too many system resources. Setting the maximum number of interfaces indexed by fixed numbers can prevent the interface index file from exceeding an expected size.
After the maximum number of interfaces indexed by fixed numbers is set, the system will allocate fixed indexes to interfaces within the specified value range. If the specified value is smaller than the number of interfaces configured on the device, the system allocates fixed interface indexes to the interfaces enabled earlier. The interfaces enabled later are not indexed by fixed numbers.
By default, a maximum of 131070 interfaces can be indexed by fixed numbers. If the value is set to 0, no interfaces will be indexed by fixed numbers.
Run:set constant-ifindex subinterface { dense-mode | sparse-mode },The memory distribution mode for the sub-interface index is set.When a sub-interface is created, the system generates an index image file for the sub-interface in the memory in a specified mode. You may use various sub-interface numbering modes, such as the continuous mode or the discontinuous mode. In real-world situations, one of the following distribution modes can be used as needed:
Sparse mode: applies to discontinuous sub-interface numbering.
Dense mode: applies to continuous sub-interface numbering.

Questions:

How to configure Traffic HG8247 Statistics Collection Interval on Huawei Quidway S2700?

Answer:
Procedure
Run:system-view,The system view is displayed.
Run:set flow-stat interval interval-time,The global traffic statistics collection interval is set.By default, the global traffic statistics collection interval is 300s.
Run:system-view,The system view is displayed.
Run:interface interface-type interface-number,The interface view is displayed.
Run:set flow-stat interval interval-time,The traffic statistics collection interval is set on the interface.By default, the traffic statistics collection interval on an interface is 300s.


NOTE:
The interval set in the system view takes effect on all the interfaces that use the default interval.
The interval set in the interface view takes effect only on this interface.
The interval set in the interface view takes precedence over the interval set in the system view.
