适用于

  • ONTAP 9
  • Aruba CX 8400 交换机 (AOS-CX 10.13.1060)
  • 跨机箱 LAG (LACP)

问题

  • 连接到配置为 VSX 对的 Aruba CX 8400 交换机后,配置了 multimode_lacp 的接口组无法联机。
  • 各成员端口在物理层面均已启动,但 ifgrp 未显示任何活动端口,且 LACP 协商失败。
EMS 日志消息:
pvif.lacp.outofsync:alert: ifgrp a0a, port e9a cannot synchronize with the LACP aggregate.
pvif.lacp.outofsync:alert: ifgrp a0a, port e9c cannot synchronize with the LACP aggregate.
  • ifconfig -v 将 LAG ID 显示为全零,表示 LACP 协商未成功。
  • Aruba 交换机日志显示对端不同步和默认状态:
LAG127 State change for interface 1/3/6: Actorstate: ALIO, Partnerstate PLIO
Partner is out of sync for interface 1/3/6
Partner is lost (timed out) for interface 1/3/6. State: DefaultedState->DefaultedState
  • ONTAP 端跟踪确认 LACP PDU 在驱动程序捕获级别没有 VLAN 标签的情况下正确发送。
  • 交换机端跟踪显示 VLAN 标记 1 附加到 LACP PDU。Aruba 交换机的本机 VLAN 处理在 ONTAP 捕获点下方添加了该标记。
