CRS通过”(admin)#show controller fabric plane all” 发现plane 1显示MCAST_DOWN, 对应在Down Flags一栏显示m.
正常应该所有均显示UP。此情况说明该平面的multicast转发已经停止,不过组播流量仍然可以通过其他7个平面转发。
此情况没有业务影响。但请尽快处理。

1个egress LC/RP 有32根 2.5Gbps的links 连接1个S3 ASIC。
1个egress LC有2个fabricq ASICs.
1个RP 有1个fabricq ASIC.
所以
下半框的LC,4根连接ASIC 2, 4根连接ASIC 3.
于是,此case中,在1平面, 在0/15/cpu0和0/sm1/sp之间总共有8根links. 已经down了一半,为了让multicast的traffic不再从PLANE 1送去0/15/cpu0,所以系统把plane 1的multicast给down了。
