This step, specifically can the main management plate of the network equipment belonging to this appointment line card, obtain from the information of the current preservation of this VSU system, such as, from the information that main management plate is preserved, obtain the capability value of the hardware table item of this VSU system, from the information that this appointment line card is preserved, obtain the capability value of the hardware table item of this appointment line card.
Step 402: judge whether the capability value of the hardware table item of VSU system is greater than the capability value of the hardware table item of specifying line card.
If the capability value of the hardware table item of VSU system is greater than the capability value of the hardware table item of specifying line card, enter step 403;
If the capability value of the hardware table item of VSU system is not more than the capability value of the hardware table item of specifying line card, directly enter step 405;
Step 403: the quantitative value obtaining the hardware table item of the current preservation of VSU system.
Step 404: judge whether the quantitative value of the hardware table item of the current preservation of VSU system is not more than the capability value of the hardware table item of specifying line card.
If the quantitative value of the hardware table item of the current preservation of VSU system is not more than the capability value of the hardware table item of specifying line card, enter step 405;
If the quantitative value of the hardware table item of the current preservation of VSU system is greater than the capability value of the hardware table item of specifying line card, enter step 406.
Step 405: change to service port by specifying the appointment non-traffic port of line card.
Step 406: cancel and will the non-traffic port of line card be specified to change to service port.
