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

Questions: 
How to configure the Constant Interface Huawei GPON  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.

How to Configure a Customized DHCP Option for the Global Address Pool on Huawei S2700?

Questions:
How to configure MA5616 a Customized DHCP Option for the Global Address Pool on Huawei Quidway S2700?

Answer:
Procedure
Run:system-view,The system view is displayed.
Run:ip pool ip-pool-name,The IP address pool view is displayed.
Run:option code [ sub-option sub-code ] { ascii ascii-string | hex hex-string | ip-address ip-address &<1-8> },The customized DHCP option is configured.After the option command is used, the specified option is carried by the DHCP Reply message returned by the DHCP server. Before using this command, ensure that you know the functions of the option to be configured. For details on DHCP options, see RFC 2132.

 NOTE:
The option command configures basic functions, such as the DNS service, NetBIOS service, and IP address lease. The system also provides commands to configure these functions separately. The commands used to configure these functions separately take precedence over the option command.
The related commands are as follows:
-DNS service: domain-name and dns-list
-NetBIOS service: nbns-list and netbios-type
-Lease: lease

How to Configure RMON Statistics Functions on Huawei S2700?

Questions:
How to configure Huawei MDU RMON Statistics Functionsl on Huawei Quidway S2700?

Answer:
Procedure
Run:system-view,The system view is displayed.
Run:interface { ethernet | gigabitethernet } interface-number,The interface view is displayed.
Run:rmon-statistics enable,RMON statistics function is enabled on an interface.
Run:rmon statistics entry-number [ owner owner-name ],A statistics table is created and an entry is added to the table.
Run:system-view,The system view is displayed.
Run:interface { ethernet | gigabitethernet } interface-number,The interface view is displayed.
Run:rmon-statistics enable,RMON statistics function is enabled on an interface.
Run:rmon history entry-number buckets number interval sampling-interval  [ owner owner-name  ],A history control table is created and an entry is added to the table.


NOTE:
-As recommended by the RMON specifications, each monitored interface should be configured with more than two history control entries. One entry is sampled every 30 seconds while another entry is sampled every 30 minutes.
-The short sampling interval enables a monitor to probe the sudden changes of traffic modes, and the long sampling interval is applicable if the interface status is relatively stable.
-Each history control table stores 10 records. When more records are generated, the old ones are overwritten.
-To reduce the impact of RMON on system performance, the sampling interval of the history control table should be longer than 10 seconds. In addition, an interface cannot be configured with too many entries for the history control table and alarm table.
-If the RMON statistics function is not enabled on an interface, statistics in the RMON statistics table and history table are 0.

How to Configure Rule for Filtering SA Messages on Huawei S9300?

Questions:
How to configure Rule for Filtering SA Messages on Huawei Quidway S9300?

Answer:
Procedure
Run:system-view,The system view is displayed.
Run:msdp [ vpn-instance vpn-instance-name ],The MSDP view is displayed.
Run:import-source [ acl { acl-number | acl-name } ],The rules for filtering multicast sources in SA messages are set.

How to Configure Log Filtering on Huawei S2700?

Questions:
How to configure Log Filtering on Huawei Quidway S2700 Huawei wholesale?

Answer:
Procedure
Run:system-view,The system view is displayed.
Run:info-center filter-id { id | bymodule-alias modname alias } * &<1-50>,info-center filter-id { id | bymodule-alias modname alias } { bytime interval | bynumber number },The filtering function is configured for specified logs.

NOTE:
-Currently, the device can filter logs or modules with a maximum of 50 log IDs or modules. If there are more than 50 log IDs or modules, the system displays a message indicating that the filtering table is full. To configure the filtering function, run the undo info-center filter-id { all | { id | bymodule-alias modname alias } * &<1-50> }, or the undo info-center filter-id { id | bymodule-alias modname alias } { bytime interval | bynumber number } command to delete original IDs or modules, and reconfigure the log ID or module.
-To add multiple IDs or modules at a time, use a space to separate IDs or modules. The system displays a message to report the result of adding each ID or module.
-You cannot add the same ID or alias name repeatedly.
-When you add an unregistered or nonexistent log ID or alias name, the system displays a message indicating that the system fails to filter the log with the specified log ID or alias name.
