适用于

  • FAS8700
  • Cisco Nexus 9300-FX2 (N9K-C93216TC-FX2)
  • 网络接口卡 (NIC) X1149A

问题描述

  • 重新启动 Nexus 交换机后,连接到 NetApp 的 Nexus 上的端口 1/73 e1a 已关闭。
  • ASUP 显示 SYSCONFIG-ANETWORK-PORTS.XML 指示 FAS8700 上的相应端口 e1a 已启动。

   slot 1: 1/10 Gigabit Ethernet Controller IX4-T
      e1a MAC Address:   b4:XX:XX:XX:XX:4c (auto-10g_t-fd-up)
      e1b MAC Address:   b4:XX:XX:XX:XX:4d (auto-10g_t-fd-up)
      Device Type:     X550, PBA H86377-006
      Firmware Version:   1.86-0.3
      Serial Number:    B49XXXXXXX4C

  • 故障排除步骤:
    1. 更换了 Nexus eth1/73 和 FAS8700 e1a之间的电缆,但 Nexus 端口 1/73 保持关闭状态。
    2. 已将配置移动到 Nexus 上未使用的端口 1/93 并已连接,但 Nexus 端口保持关闭状态。
  • ifgroup a0a 配置为 multimode_lacp 使用 e1ae1b,但 e1a 处于 Down Ports 状态,"Port Participation" 为 "partial"。
  • "IFSTAT -A" 显示了很多 CRC errorstotal errors
