Understand the certification

Nexus 数据中心环境的高级故障排除考试 — 真正在排障岗位上的 DC 工程师考这个最实用。

300-615 DCIT(Troubleshooting Cisco Data Center Infrastructure)是 CCNP Data Center 的故障排除专项,60 题 / 90 分钟。和 DCID(设计)互补,DCIT 专注于"东西坏了怎么修"。

考试覆盖 Nexus 交换机故障排除(vPC peer-link 故障、HSRP/VRRP 切换异常)、VXLAN EVPN 排障(BGP EVPN 邻居建立失败、VTEP 不通)、ACI 故障排除(Fault/Health Score 分析、EPG 通信异常)、SAN 存储网络排障(FC zone 配置错误、FLOGI 失败)。

约 40% 的题以 show 命令输出为题干 — 给你一段 show vpc、show nve peers 或 show system internal 的输出,问你故障原因和修复方法。

Included in your preparation

  • 5 structured chapters focused on the exam topics
  • 135 practice questions with explanations
  • Timed mock exam practice
  • A troubleshooting-first study path instead of a generic revision set
  • Coverage of Nexus, UCS, SAN, and ACI troubleshooting

2. 第二阶段:VXLAN EVPN + ACI 排障(2-3 周)

VXLAN EVPN 的 BGP EVPN neighbor 建立失败排查(show nve peers、show bgp l2vpn evpn)。ACI 的 Fault 和 Health Score 系统、moquery 命令、APIC 日志分析。

3. 第三阶段:SAN 排障 + 模考(1-2 周)

FC SAN 的 FLOGI/PLOGI 过程、zone 配置错误排查、MDS 交换机的 show flogi database。做 2 套模考,训练从 show 命令输出快速定位故障点的能力。

Career value

DC 故障排除是一线运维的核心技能,DCIT 的实用性在 CCNP DC 所有专项中排第一。银行和电信的 DC 团队在招人时经常把 DCIT 作为加分项。

适合考的人:日常工作就是在 Nexus 环境里排障的 DC 工程师,有 vPC 和 VXLAN 实操经验。

不适合考的人:没有 Nexus 实操经验的人 — 考试全是 show 命令输出分析,没实操背景根本看不懂。

Preparation tips

    Common mistakes

    • **忽略 SAN 排障** — 很多人只准备 LAN 部分,但 FC SAN 占约 15-20% 权重,MDS 的 show flogi database 和 zone 配置排错必考。
    • **不熟悉 NX-OS 诊断命令** — show system internal 系列命令在真考中出现频率很高,不是日常用的 show interface 那些。
    • **ACI Fault Code 不认识** — ACI 的 F 开头故障码(如 F0467 表示 EPG 无端口绑定)要能快速判断故障类型。

    Learner experiences

    Loading reviews…

    日常工作就是排 Nexus 的障,考起来相对轻松。最意外的是 SAN 排障题比预期多 — FC zone 和 FLOGI 至少出了 4 题。如果没碰过 MDS 交换机,这部分要专门补。
