双活环境中,光纤交换机级联端口如何详细设计和具体配置?

1.背景: 双活存储VMAX200k,承载主备中心数据库 光纤交换机F96(fabric 扩展license) 华为波分DWDM OptiX OSN 8800,两对波分和SAN交换机由三家运营商的两条裸光纤组成,一条为移动,另一条为电信联通冗余;
2.在SAN交换机中做了virtual fabric,虚拟机交换机中只有级联和存储SRDF端口,速率为8Gbps
3.级联端口配置:

4.其他配置是如何设置的?
1)LOS TOV enable: 建议设置为ON,FC交换适当开启告警防抖功能。
2)2、Fillword:对于FC8G及以上速率,Fillword建议设置为ARB(FF),并使用mode3( ARB/ARB then IDLE/ARB );对于FC4G/2G/1G,fillword设置为Idle即可,使用Mode 0(IDLE/IDLE)
3)Trunk Port:建议设置为OFF。否则可能因为时延差问题导致TRUNK失效
4)ISL R_RDY Mode
5)Credit Recovery
6)Port Fencing设置和策略
5.现有SAN交换机经常出现告警:
2020/08/04-03:00:19, [C3-1023], 146776, CHASSIS, WARNING, IBM_2498_F96, Single RDY/Frame Loss detected and recovered on Slot 0,Port 94(180) rdy(0x0)/frame(0x8).
已经寻求厂商给出解决方案,建议找波分厂商给建议,波分厂商建议更换光模块,但对底层的运营商抖动无法察觉。在应急处置上,请问有没有什么好的办法?
