Embodiment
When the network equipments configuration modification is frequent, removes to follow the trail of the deploy content that was modified each time and just become difficult.When in that needs are all or part of when dynamic-configuration is reverted to default value, generally need check the dynamic-configuration of current operation and the difference of default value earlier, the dynamic-configuration that these have been modified reverts to default value then.The embodiment of the invention is collected the content of all or part of dynamic-configuration different with default value as required automatically, then it is reverted to default value.
Be explained in detail to the main realization principle of embodiment of the invention technical scheme, embodiment and to the beneficial effect that should be able to reach below in conjunction with each accompanying drawing.
As shown in Figure 1, the main realization principle process of the embodiment of the invention 1 is as follows:
The method of obtaining the network equipment dynamic-configuration deploy content different with default value has multiple, for example, can obtain different deploy contents with default value by all dynamic-configuration of comparing cell equipment; Different deploy contents is obtained in modification that also can tracking network equipment dynamic-configuration.Present embodiment obtains corresponding deploy content by the operating instruction of collection network equipment dynamic-configuration.
On the network equipment, in order to preserve the deploy content parameter of operation, usually employing will move the mode that deploy content is reduced to configuration-direct, then as long as on nonvolatile storage, preserve these configuration-directs, when network equipment system restarts, carry out the modification that these configuration-directs that are saved just can be realized corresponding configuration.In order to save the space, the content of preservation only is the deploy content different with default value in the operation deploy content parameter.Therefore, as long as obtained to be reduced to the operation deploy content of configuration-direct, also just obtained the network equipment dynamic-configuration deploy content different with default value.
After having obtained deploy content, just can generate and recover instruction according to deploy content.Recovery instruction here and deploy content are corresponding, every corresponding corresponding instruction that recovers of deploy content.Usually generating the method for recovering instruction according to deploy content is one by one deploy content oppositely to be revised as instruction, is to recover instruction.
In practical operation, only one by one deploy content oppositely is revised as and recovers instruction, conflict many times can appear, it is the needs of default value that the recovery instruction that generates can not be satisfied recovery network equipment dynamic-configuration, therefore, present embodiment adopts different amending methods to different deploy contents, so that the recovery that generates instruction meets the demands.
Here the grammer with dos command line DOS interface commonly used is an example, represents negate to the deploy content instruction with English word no, represents that with English word default instruction uses as default key1, key2 to deploy content ... keyn represents the various parameters in the grammer.The method that the concrete generation according to deploy content recovers instruction is as follows:
If 1 deploy content is as follows:
key1?key2…keyn
Then the recovery of negate instruction is:
no?key1?key2…keyn
The recovery instruction that recovers default value is:
default?key1?key2…keyn
Can close and be written as { no|default}key1 key2 ... keyn, wherein { no|default} is illustrated in the two must select one of them.
2, usually, (or no prefix as required), just can revert to default value with network equipment dynamic-configuration as long as add the default prefix before configuration-direct.But the default value of network equipment dynamic-configuration enable certain function exactly, and deploy content is the negate of function just sometimes, and for example, deploy content is:
no?key1?key2…keyn
To not meet grammer after adding default prefix (or no prefix) this moment:
Default no key1 key2 ... keyn or
no?no?key1?key2…keyn
Therefore, prefix need be carried out cancellation and handle, default no and no no prefix effect are cancelled out each other, and recover instruction and just become:
key1?key2…keyn
3, some in particular cases, the grammer that recovers instruction is different with configuration-direct, does not need to import whole parameters usually as deploy content, for example:
Configuration-direct is:
key1?key2…keyn
And recover instruction only need for:
{no|default}key1?key2
If directly add prefix at original deploy content this moment, then will not meet grammer thereby cause instructing because of unnecessary order parameter is arranged.Need erase unnecessary part this moment, and the foundation of erasing is: after instruction analysis arrived parameter key2, instruction can intactly finish, and then the part of back is unnecessary parameter just.
But, if optional parameters is arranged in the deploy content, in for example following deploy content, all be optionally (being expressed as within " [" and "] " optional content) except key1, key2:
key1?key2[…keyn]
Then following recovery instruction all is legal:
{no|default}key1?key2
{no|default}key1?key2…keyn
Therefore, when generate recovering instruction,, in the back instruction of analysis, can erase the parameter after the key2 by mistake, cause instructing ambiguity (conflicting) or lose parameter with last according to the rule that provides previously.For fear of this situation occurring, before whether decision needs to erase parameter, need test whether fully grammaticalness of the instruction that adds after the prefix earlier, if meet, just no longer erase any parameter.
4, the parameter of deploy content has ordinal relation, because if these parameters are kept in the nonvolatile storage, when needs reconfigure, will carry out in order.Therefore, if there is the logic dependence in deploy content, then recover instruction order must and the reversed in order of deploy content, if do not have dependence then unnecessary.
If when in the deploy content of the network equipment, existing more and complicated logical order to concern, can adopt the method for dividing and rule: obtain the deploy content parameter that dependence is arranged fritter, relatively independent earlier, and it is reverted to default value; And then obtain the more deploy content parameter that dependence is arranged of bulk (content that be embedded in the fritter of bulk inside this moment has been a default value, can not embody again), again it is reverted to default value; By that analogy, obtain and recover not have at last the deploy content parameter of dependence again, all recover until the deploy content parameter of required recovery.For example network equipment dynamic-configuration is as follows:
cmd-1
cmd-2
subcmd-21
subcmd-22
cmd-3
subcmd-31
subcmd-32
Wherein:
Subcmd-21 and subcmd-22 instruction rely on the cmd-2 instruction;
Subcmd-31 and subcmd-32 instruction rely on the cmd-3 instruction;
Cmd-2 and cmd-3 instruction rely on the cmd-1 instruction;
When the dynamic-configuration of configure network devices, by arranged in order is no problem from top to bottom, and when recovering default value because dependence can not be according to this order.Therefore, elder generation obtains from the configuration of part, obtains and recover to depend on the local configuration (do not rely between cmd-2 and the cmd-3 instruction, it doesn't matter for whose back of whose elder generation) of cmd-2 and cmd-3 instruction respectively.Obtain the configuration of the overall situation then, be at this moment:
cmd-1
cmd-2
cmd-3
Do not had the local configuration of cmd-2 and cmd-3 instruction, can recover this moment by order from bottom to top.
After generating corresponding recovery instruction, recover instruction by carrying out, just can say that network equipment dynamic-configuration reverts to default value.
The method that present embodiment provides when needs recover network equipment dynamic-configuration, can revert to default value with deploy content effectively.Owing to be the artificial thinking of simulation, deploy content is transferred to recover instruction, can recover the situation of default value in theory by artificial execution command, can recover by the method for present embodiment, can reduce manual operation like this, reduce the network management burden.
As shown in Figure 2, be the main realization principle flow chart of the embodiment of the invention 2, specific as follows:
The method of obtaining the network equipment dynamic-configuration deploy content different with default value has multiple, for example, can obtain different deploy contents with default value by all dynamic-configuration of comparing cell equipment; Different deploy contents is obtained in modification that also can tracking network equipment dynamic-configuration.Present embodiment obtains corresponding deploy content by the operating instruction of collection network equipment dynamic-configuration.
Here, the parameter of common deploy content has ordinal relation, because if these parameters are kept in the nonvolatile storage, when needs reconfigure, will carry out in order.Therefore, if there is the logic dependence in deploy content, then recover instruction order must and the reversed in order of deploy content, just backward is carried out, if do not have dependence then unnecessary.
If when in the deploy content of the network equipment, existing more and complicated logical order to concern, can adopt the method for dividing and rule: obtain the deploy content parameter that dependence is arranged fritter, relatively independent earlier, and it is reverted to default value; And then obtain the more deploy content parameter that dependence is arranged of bulk (content that be embedded in the fritter of bulk inside this moment has been a default value, can not embody again), again it is reverted to default value; By that analogy, obtain and recover not have at last the deploy content parameter of dependence again, all recover until the deploy content parameter of required recovery.
