适用场景

  • AFF / FAS 系统
  • ONTAP 9.x
  • Cisco集群网络交换机

问题描述

  • system health alert show 命令报告以下错误:
Node:NetApp1
Resource: Ethernet1/10
Severity: Major
Indication Time: Mon Apr 24
13:01:43 2023
Suppress: false
Acknowledge: false
Probable Cause: The percentage of inbound packet errors of switch
interface "int/Ethernet1/10"
is above the warning threshold.
Possible Effect: Communication between nodes in the cluster might be
degraded.
 
  • EMS中报告了以下错误:
[?] Mon May 01 01:06:49 +0530 [NetApp-node1: cshmd: hm.alert.raised:alert]: Alert Id = ClusterIfInErrorsWarn_Alert , Alerting Resource = switch-01(XXXXXXXXXXX)/Ethernet1/10 raised by monitor ethernet-switch

  • 根据show interface输出、交换机端口上的MTU为1500:
switch-01# show interface <interface name>
 
Ethernet1/8 is up
admin state is up, Dedicated Interface
Hardware: 1000/10000/25000/40000/50000/100000 Ethernet, address: 806a.0023.eaf4 (bia 806a.0023.eaf4)
MTU 1500 bytes, BW 40000000 Kbit , DLY 10 usec
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, medium is broadcast
 
  • 在存储端、MTU大小设置为9000、可从 net port show 命令行界面的输出进行验证
