适用场景

集群网络交换机(CNS) Broadcom BES-53248
集群端口以不同速度运行的交换集群：10G和40G

问题描述

将新节点从其他平台迁移到现有集群时出错。示例：

Cluster network RPC communication test from local address 169.254.99.130 to 169.254.247.154
 Error: Cluster network RPC communication test from local address 169.254.99.130 to 169.254.247.154 failed with subsequent larger RPC request of size 1024 where size 0 succeeded. Possible MTU mismatch on cluster network ports or network switch. 
 Reason: f_echo_1: RPC: Timed out; netid=tcp fd=253 TO=5.0s TT=5.001s O=1076b I=0b CN=275/2 VSID=-3 169.254.99.130:40455 <-> 169.254.247.154:7815. Verify the network configuration.

ONTAP事件消息(Event Messages，EMS)报告A ClusterSwitchConnectivity_Alert。示例：

[node_name: mgwd: callhome.hm.alert.major:alert]: Call home for Health Monitor process cshm: ClusterSwitchConnectivity_Alert[node_name]. [node_name: cshmd: hm.alert.raised:alert]: Alert Id = ClusterSwitchConnectivity_Alert , Alerting Resource = node_name raised by monitor ethernet-switch

从CNS日志中、我们可以看到相同端口组中的某些链路停机：

switch_name TRAPMGR[trapTask]: traputil.c(753) 34807 %% NOTE Link Down: 0/5, Reason Code: 0x62 <189> switch_name TRAPMGR[trapTask]: traputil.c(753) 34806 %% NOTE Link Down: 0/6, Reason Code: 0x62 <189> switch_name TRAPMGR[trapTask]: traputil.c(753) 34799 %% NOTE SFP inserted in 0/7
