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

Questions: 

How to configure the Huawei Access  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.

How to Configure Automatic Saving of DHCP Data on Huawei S2700?

Questions:
How to configure Automatic Huawei GPON Saving of DHCP Data on Huawei Quidway S2700?

Answer:
Procedure
Run:system-view,The system view is displayed.
Run:dhcp server database enable,The function that saves DHCP data to the Flash memory is enabled.After this command is executed, the system generates the lease.txt and conflict.txt files in the Flash memory. The two files save the address lease information and address conflict information.
Run:dhcp server database write-delay interval
The interval for saving DHCP data is set.
After the device is configured to automatically save DHCP data, the device saves data every 7200 seconds by default and the latest data overwrites the previous data.
Run:dhcp server database recover,The DHCP data in the storage device is restored.After this command is executed, the device restores DHCP data in the Flash memory.

How to Configure Basic SNMPv1 Functions on Huawei S2700?

Questions:
How to configure Basic Huawei Access SNMPv1 Functions on Huawei Quidway S2700?

Answer:
Procedure
Run:system-view,The system view is displayed.
Run:snmp-agent,The SNMP agent function is enabled.By default, the SNMP agent function is disabled. By executing the snmp-agent command with any parameter enables the SNMP agent function.
Run:snmp-agent sys-info version v1,The SNMP version is set to SNMPv1.By default, SNMPv3 is enabled.After SNMPv1 is enabled, the managed devices support SNMPv1 and SNMPv3 and can be monitored and manged by both SNMPv1 and SNMPv3 NMSs.
Run:snmp-agent community { read | write } { community-name | cipher community-name },The community name is set.The community name will be saved in encrypted format in the configuration file.By default, the complexity check is enabled for a community name. If a community name fails the complexity check, the community name cannot be configured. To disable the complexity check for a community name, run the snmp-agent community complexity-check disable command.

 NOTE:
The default minimum length of a community name is six characters. The set password min-length command determines the minimum length of a community name.
A community name includes at least two kinds of characters, which can be uppercase letters, lowercase letters, digits, and special characters except question marks (?) and spaces.
Ensure that the community name of the NMS is the same as that set on the agent. If the NMS and the agent have different community names, the NMS cannot access the agent.
