In the practical application, the deploy content of communication apparatus may change, and the version of configuration file just needs correspondingly upgrading so fast.Communication apparatus can judge whether quick configuration file is correct according to version information, if fast the version of configuration file does not meet the requirement of communication apparatus, it is incorrect then to be judged as quick configuration file, stops configuration.
Perhaps, communication apparatus also can judge whether quick configuration file is correct according to check information, if check information indication makes a mistake, deploy content may be distorted, and it is incorrect then to be judged as quick configuration file, stops configuration immediately.
Perhaps, communication apparatus also can judge according to version information and check information whether quick configuration file is correct simultaneously, if version information and check information are all correct, just continues configuration; Otherwise, stop configuration.
Certainly, in the practical application, configuration file can not have file header yet fast, so, can omit step 201～step 202.
Step 203: read the quick configuration order of article one in the quick configuration file.
Step 204: extract the parameter of quick configuration order, determine command id according to the overall identification of parameter.
In the present embodiment because high 24 bits of parameter global sign are exactly command id, can with the overall identification of parameter and FFFFFF00H with, keep high 24 information, with the acquisition command id.
Step 205:, determine and quick configuration order corresponding processing function according to command id query mappings table.
Step 206: the parameter in the quick configuration order as the processing function parameters of determining, is called definite processing function, and the processing function is configured according to the parameter of quick configuration order.
Step 207～step 208: judge whether to handle all quick configuration orders, if then withdraw from this flow process; Otherwise, read the quick configuration order of next bar, and execution in step 204.
