由于ARP风暴、ifgrp端口出现间歇性波动
适用场景
ONTAP 9
问题描述
- 由于物理端口上收到ARP风暴、ifgrp中的端口正在闪烁：
Sat Feb 10 23:19:21 -0600 [Node-01: kernel: netinet.ethr.arpstorm:error]: The node detected a possible ARP storm on port a0a-192. Detected rate: 5001 packets per second.
Sun Feb 11 04:19:36 -0600 [Node-01: kernel: netinet.ethr.arpstorm:error]: The node detected a possible ARP storm on port a0a-192. Detected rate: 740946 packets per second. - 日志指示两个端口中有一个端口间歇性地转换为非活动和活动状态、直到ARP风暴停止。
Sat Feb 10 23:39:12 -0600 [Node-01: intr: net.ifgrp.lacp.link.inactive:error]: ifgrp a0a, port e0g has transitioned to an inactive state. The interface group is in a degraded state.
Sat Feb 10 23:39:17 -0600 [Node-01: intr: net.ifgrp.lacp.link.active:notice]: ifgrp a0a, port e0g has transitioned to the active state.
Sat Feb 10 23:47:36 -0600 [Node-02: intr: net.ifgrp.lacp.link.inactive:error]: ifgrp a0a, port e0e has transitioned to an inactive state. The interface group is in a degraded state.
Sat Feb 10 23:47:41 -0600 [Node-02: intr: net.ifgrp.lacp.link.active:notice]: ifgrp a0a, port e0e has transitioned to the active state. - 端口进入降级状态、导致链路关闭、LIF迁移到其他节点。
