Technical field

The present invention relates to the field of communications, and in particular to a port attribute inheritance method and apparatus.

Background technique

In the current data communication device, when the configuration data is saved in the normal state, the port attribute is saved, and then the result is read out again when the data is loaded again. If the configuration file is modified or the system hardware changes, then the resource check is performed. The result may be incorrect. It needs to be recalculated. If the previous resource check result is used, the current version may be affected. The subsequent interface report and configuration command process will encounter resource check errors.

The current data communication equipment also has the following problems:

(1) If the board is switched during system operation, such as plugging or unplugging an interface card or plugging or unplugging a line card, resources are usually deleted. As a result, the original interface configuration is lost after the new board is plugged in.

(2) If the subcard is pulled out and a new type of subcard is reinserted during the system operation, the original configuration cannot be inherited due to the different subcard types before and after the plugging, and the new subcard interface can only restore the default configuration. ;

(3) If the system is reset, replace the board or daughter card. After the system is restarted, the interface configuration is lost because the resource is not saved. You need to reconfigure it.

In the first processor, the second processor, and the third processor.

For the above technical problems existing in the related art, the following description will be made in conjunction with the optional embodiments, which are combined with the above embodiments and their optional embodiments.

The main purpose of this alternative embodiment is to provide a method for inheriting port attribute of a data communication device to solve the problem existing in the existing device.

The storage port is used to save the original port attributes when the data communication device hardware changes. After the new port is brought online again, all or part of the previous configuration is delivered according to the specific conditions to implement port attribute inheritance.

The specific steps are as follows:

(1) During the operation of the data communication device, the system hardware changes, such as port removal, save the port configuration attribute, and update the previously saved port configuration attribute;

(2) When the system hardware changes again, such as the port is loaded again, check the hardware properties;

If the hardware attributes are the same as those of the previous hardware, re-deliver the port attribute configuration to make the port attribute recovery consistent with that before the port is removed.

If the hardware attribute is inconsistent with the previous step (1), the port attribute configuration is delivered in whole or in part according to the situation, so that the port attribute is inherited as much as possible;

(3) If the system hardware properties change again, repeat step (1).

Specific implementations of this alternative embodiment are:

(1) The plug-in operation of the same board, the interface and service configuration remain unchanged.

(2), interface sub-card replacement, pull out the sub-card, insert a different type of sub-card:

If the interface type of the new daughter card is the same as the interface type of the atomic card, the interface and configuration are inherited;

If the number of interfaces of the new daughter card is large, the atomic card interface attribute is partially inherited, and the extra interface uses the default configuration;

If the number of interfaces of the new subcard is small, the interface of the original interface card is offline;

The interface type of the new daughter card is different from the interface type of the original daughter card. The interface of the original daughter card is offline, and the interface of the new daughter card is valid, but the default configuration is used.

(3) The line card and the service card are directly replaced, the old interface is offline, the new interface is online, and the new interface has only the default configuration.

(4) Redundant historical interface and configuration data support command deletion. When the subcard is hot swapped or the board is offline, the related interface configuration information is generated to generate channelized interface data, and the identifier bit is reserved. When the daughter card is re-plugged, the physical interface is reported to the database, and the default configuration is delivered to the port instead of inheriting the previous port attribute.

In an optional embodiment, the process of implementing the same block hot swap attribute inheritance is implemented according to the product of the optional embodiment;

In step (1), during the running of the system, a board is pulled out, the database saves the port configuration attribute, and the previously saved port configuration attribute is updated.

In the step (2), when the board is inserted again, the system compares the board type and can determine that the board is the same type as the last board.

In step (3), the system re-delivers the port attribute saved in step 1.

In another optional embodiment, the flow chart of the interface card hot plug configuration inheritance flow chart according to the present invention is used;

FIG. 3 is a flowchart of inheritance of an interface card hot plug configuration according to an embodiment of the present invention, as shown in FIG. 3:

In the running of the data communication system, the scene where the interface card is hot swapped occurs:

After the interface card is removed, the database adds a flag to the interface configuration for saving without deleting.

When the interface card is plugged in, it will be judged:

(1) If the interface card of the same type is inserted, the new interface card is configured and delivered from the database. After the configuration is normally sent, the flag is cleared in the data. Thereby completing the interface configuration inheritance.

(2) If a different type of interface card is plugged in, it will determine whether the new type of interface card is the same type as the original interface card. For example, the same as the 1G Ethernet port or the same as the POS port.

(3) If the interface types of the new and old interface cards are the same, perform interface configuration check. If the number of new subcard interfaces is more than the old subcards, the port attributes are inherited in the order of the ports, and the extra ports are configured by default. If the number of new subcard interfaces is smaller than the old subcard, the port attribute flag is not cleared after the port attribute is inherited in the order of the port, and the reservation is continued.

(4) If the interface type of the new and old interface cards is different, the old card configuration is saved, and the new card is configured by default.

Yet another alternative embodiment is the line card and service card attribute inheritance process according to the present alternative embodiment;

In step (2), when a service card is re-inserted in the slot of the line card, the system checks the board type and the interface type is different.

In step (3), the system sets the flag of the attribute saved in step (1) and saves it, but does not re-issue it.

In summary, the technical solution in the present invention solves the problem that the original configuration cannot be inherited in the process of switching the board in the related art, and further realizes the effect of inheriting the original configuration after the board switching.
