升级集群交换机后从集群LIF执行pinging时、数据包持续丢失
适用场景
- Cisco NX3232C集群网络交换机(CNS)
- NX-OS固件更新
- RC框架 固件从1.8或更早版本更新到1.10或更高版本
问题描述
- 所有节点持续报告：
[vifmgr: vifmgr.cluscheck.ctdpktloss:debug]: Continued packet loss when pinging from cluster lif node-01_clus-1 (node node-01) to cluster lif node-02_clus2 (node node-02).对彼此的集群生命周期执行pinging时。
- 一半集群ping集群失败。示例：
::*> cluster ping-cluster -node node-01
...
Basic connectivity succeeds on 14 path(s)
Basic connectivity fails on 14 path(s)
...
Larger than PMTU communication succeeds on 14 path(s)
RPC status:
14 paths up, 0 paths down (tcp check)
14 paths up, 0 paths down (udp check)
- 每次将连接到交换机1的集群端口还原为交换机2的LIF时：
- EMS报告的消息类似于：
