验证Catalyst 9000系列交换机上的第2层硬件
目录
简介
本文档介绍如何验证Catalyst 9400系列交换机上的第2层硬件编程和转发。
先决条件
要求
本文档没有任何特定的要求。
使用的组件
本文档中的信息基于Catalyst 9400(UADP 2.0)系列交换机。
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。
背景信息
- Catalyst 9400 Supervisor1(C9400-SUP-1)具有3个UADP 2.0转发ASIC(0、1、2)。
- 每个UADP 2.0转发ASIC具有：
- 双核(0、1) — 这在前几代UADP 2.0 ASICS中不存在。
- SIF（堆栈接口） — 用于通过内部堆栈环连接到其他2个UADP 2.0 ASIC。
- NIF（网络接口） — 用于通过背板连接到1个或多个线路卡。
- 线卡和管理引擎上行链路接口的所有数据包转发决策由活动管理引擎上的3个UADP 2.0转发ASIC做出。
- 本示例中使用的线卡有1个线卡单核末节ASIC，它不参与数据包转发决策。
- 线卡上的线卡末节ASIC通过背板连接到Supervisor上的3个UADP 2.0转发ASIC中的1个或更多。
- 管理引擎上的3个UADP 2.0转发ASIC做出所有数据包转发决策。

成功的硬件编程
所有功能（无论是MAC地址、接口、VLAN等）都存储在对象数据库中，并作为对象编程到硬件中。
RP对FP编程，FP对FED编程，然后FED最终对管理引擎转发ASIC硬件编程。RP软件条目作为对象存储在对象数据库中，而FP软件条目作为异步对象存储在对象数据库中。
当FP对FED进行编程（FED反过来对管理引擎转发ASIC进行编程）时，FED会向FP发回确认。然后，FP将其转发到RP，以指示硬件编程成功完成。如果FED硬件编程缺失或不正确，您可以使用下一命令检查问题和/或确认。
C9400#show platform software object-manager fp active statistics Forwarding Manager Asynchronous Object Manager Statistics Object update: Pending-issue: 0, Pending-acknowledgement: 0 Batch begin: Pending-issue: 0, Pending-acknowledgement: 0 Batch end: Pending-issue: 0, Pending-acknowledgement: 0 Command: Pending-acknowledgement: 0 Total-objects: 3269 Stale-objects: 0 Resolve-objects: 0 Error-objects: 0 Paused-types: 0
如果上一个命令显示处于挂起发出状态的非零对象，请使用此命令查找涉及的对象编号：
C9400#show platform software object-manager fp active pending-issue-update
然后，使用此命令确定与对象编号关联的停滞进程：
C9400#show platform software object-manager fp active object {object#}
在RP端，使用此命令检查FP未确认的对象的删除挂起（删除挂起）。

线卡统计信息 — 管理引擎到线卡数据路径
检查与特定前面板接口关联的线卡线卡末节ASIC统计信息。在本例中，接口Gig1/0/13是重点。
输出示例：
-
从Gig 1/0/13接收的数据包，进入网络接口接收端口并通过IQS进入堆栈接口。
-
从那里，数据包要么从堆栈接口发出到另一个Supervisor ASIC，要么通过SQS、AQM、EQC、ESM、RWE返回，然后从网络接口发送Gig 1/0/13。
-
从Gig 1/0/13出口的其他Supervisor ASIC接口发送的数据包进入Sif，然后通过SQS、AQM、EQC、ESM、RWE，然后通过Gig 1/0/13的NifTx。
-
对于AQM，有8个Tx队列。如果从这些队列中看到丢包，可以使用此命令确定哪个队列遇到丢包：show platform hardware fed active goes queue stats interface Gig 1/0/13

从线卡的角度检查前面板接口的流量控制状态。这有助于识别接口上的任何拥塞。
- 如果没有流控制，则值为“ — ”，否则将指示遇到流控制（拥塞）的队列编号。
- 接口收到的流量控制从线卡上的线卡ASIC传递到Supervisor上的Supervisor ASIC，在Supervisor ASIC上通常可以看到AQM丢弃。OCI（带外控制接口）是线卡和活动Supervisor之间的内部通信通道，用于向Supervisor发送从线卡到Supervisor的流控制信号。
