Fortigate HA 的 5分钟问题

将两台FG60B，不选择monitor interface，配置相同的优先级，同时启动。

FGT60B3909686179 # get sys ha status
Model: 60
Mode: a-p
Group: 0
Debug: 0
ses_pickup: enable
Master:200 FGT60B3909686179 FGT60B3909686179 0
Slave :200 FGT60B3909225035 FGT60B3909225035 1
number of vcluster: 1
vcluster 1: work 169.254.0.1
Master:0 FGT60B3909686179
Slave :1 FGT60B3909225035

1 监控活跃端口个数相同。（都是0个）

2 HA运行时间形同。（相差未超过5分钟）

3 优先级相同。（都为200）

4 序列号大的为主。（FGT60B3909686179 为主）

FG FGT60B3909686179 比 FGT60B3909225035 晚0.6秒。（这个时间是加入HA的时间）

使用 diagnose sys ha reset-uptime 进行软切换。因为 time 时间相差未够5分钟。切换失败，FGT60B3909686179继续为主。

不停的利用软切换方式，将HA时间差值增大到5分钟（3000/10/60=5 ）。当到达3000后，设备进行了正常的主备切换。状态从work 变为 standy 。
