根据记录的信息发现双机热备时的优先级为49004,USG9520双机热备VGMP优先级怎么算的?

根据优先级的计算法则(USG9520无SFU,不参与SFU优先级计算):
•每块接口板的优先级计算为:1000 * (接口板上插卡个数)。若有n块接口板在位,则设备的优先级为45000 + n块接口板的优先级之和。
•每块SPU板的优先级计算为:2 * (业务板上CPU个数),若有n块SPU板在位,则设备的优先级为45000 + n块SPU板的优先级之和.
•SFU板默认不参加优先级计算,但是为了提高系统的可靠性,当SFU板在位个数小于指定的在位个数时,优先级会降低,具体如下:
USG9310和USG9320 SFU是n+1备份(n默认值为3)。
USG9520无SFU,不参与SFU优先级计算。
USG9560 SFU是n+1备份(n默认值为2)。
USG9580 SFU是n+1备份(n默认值为3)。
当SFU板在位个数m小于指定在位个数n时,设备优先级会降低,降低的优先级计算公式为45000 -2 * (n-m)。
通过查看接口板及插卡数量,以及查看SPU板的CPU个数,如下:

最后的优先级应该为45000+1000*4+2*3=49006,为什么会为49004呢?这是因为SPU里的CPU6 是管理CPU,不参与优先级的计算,所以最后的优先级为49004。
附:USG9000 VGMP优先级的计算方法
USG9000内置一个VGMP管理组,初始优先级为45000。每块单板的优先级计算如下:
SFU板默认不参加优先级计算,但是为了提高系统的可靠性,当SFU板在位个数小于指定的在位个数时,优先级会降低,具体如下:
当SFU板在位个数m小于指定在位个数n时,设备优先级会降低,降低的优先级计算公式为45000 -2 * (n-m)。
每个链路或接口故障时,观察该链路或接口的VGMP管理组的优先级将会降低2。
单板故障时,观察该单板的VGMP管理组的优先级降低的数值计算方法与上面优先级计算方法一致。
