排除Catalyst 9000交换机上的EtherChannel故障
简介
本文档介绍如何了解Catalyst 9000系列交换机上的EtherChannel并对其进行故障排除。
先决条件
要求
Cisco 建议您了解以下主题：
- Catalyst 9000系列交换机架构
- Cisco IOS® XE软件架构
- 链路聚合控制协议 (LACP) 和端口聚合协议 (PAgP)
使用的组件
本文档中的信息基于以下硬件版本：
- Catalyst 9200
- Catalyst 9300
- Catalyst 9400
- Catalyst 9500
- Catalyst 9600
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
有关限制、限制、配置选项和注意事项的最新信息，以及与此功能相关的任何其他详细信息，请参阅Cisco正式发行说明和配置指南。
EtherChannel在交换机、路由器和服务器之间提供容错高速链路。 使用EtherChannel增加设备之间的带宽，并将其部署在网络中可能出现瓶颈的任何位置。EtherChannel为链路丢失提供自动恢复，它会在剩余链路之间重分配负载。如果链路发生故障，EtherChannel会将流量从故障链路重定向到信道中的其余链路，无需干预。
EtherChannel可以配置为不协商，也可以使用链路聚合协议（PAgP或LACP）支持动态协商。
当您启用PAgP或LACP时，交换机将了解合作伙伴的身份和每个接口的功能。然后，交换机将具有类似配置的接口动态分组到单个逻辑链路（通道或汇聚端口）中；交换机根据硬件、管理和端口参数限制对这些接口组进行分组。
LACP标志
LACP标志用于在端口通道启动时协商端口通道参数。看看每面旗帜的含义：
| 标志 |
状态 |
| LACP活动（不太重要的位） |
0 =被动模式 1 =主动模式 |
| LACP Timeout：表示LACP发送/接收超时 |
0 =长超时。3 x 30秒（默认） 1 =短超时。3 x 1秒（LACP速率快速） |
| 汇聚 |
0 =单个链路（不考虑聚合） 1 =可聚合（潜在的聚合候选对象） |
| 同步 |
0 =链路不同步（非良好状态） 1 =链路处于同步状态（正常状态） |
| 收集 |
0 =未准备好接收/处理帧 1 =准备接收/处理帧 |
| 分发 |
0 =未准备好发送/传输帧 1 =准备发送/传输帧 |
| 已违约 |
0 =将接收的PDU中的信息用于合作伙伴 1 =它使用合作伙伴的默认信息 |
| 已过期（最高位） |
0 = PDU已过期， 1 = PDU有效 |
LACP标志的预期值为0x3D（十六进制）或0111101（二进制），以达到P（捆绑在端口通道中）状态。
.... ...1 = LACP Activity (less significant bit)
.... ..0. = LACP Timeout
.... .1.. = Aggregation
.... 1... = Synchronization
...1 .... = Collecting
..1. .... = Distributing
.0.. .... = Defaulted
0... .... = Expired (most significant bit)

验证LACP操作
本节介绍如何验证LACP协议的正确状态和操作。
基本检查
使用以下命令检查LACP输出：
show lacp sys-id
show lacp <channel-group number> neighbor
show lacp <channel-group number> counters
show interfaces <interface ID> accounting
debug lacp [event|packet|fsm|misc]
debug condition <condition>
第一个命令输出显示了交换机系统ID及其优先级（对于LACP）。
switch#show lacp sys-id
32768, f04a.0206.1900 <-- Your system MAC address
检查LACP邻居的详细信息，例如运行模式、邻居系统Dev ID及其优先级。
switch#show lacp 1 neighbor
Flags: S - Device is requesting Slow LACPDUs
F - Device is requesting Fast LACPDUs
A - Device is in Active mode P - Device is in Passive mode
Channel group 1 neighbors

Gi1/0/1 SA 32768 f04a.0205.d600 12s 0x0 0x1 0x102 0x3D <-- Dev ID: Neighbor MAC Address
Gi1/0/2 SA 32768 f04a.0205.d600 24s 0x0 0x1 0x103 0x3D <-- Dev ID: Neighbor MAC Address
Gi1/0/3 SA 32768 f04a.0205.d600 16s 0x0 0x1 0x104 0x3D <-- Dev ID: Neighbor MAC Address
Gi1/0/4 SA 32768 f04a.0205.d600 24s 0x0 0x1 0x105 0x3D <-- Dev ID: Neighbor MAC Address
验证每个接口发送和接收的LACP数据包。如果检测到损坏的LACP数据包，则Pkts Err计数器将会增加。
switch#show lacp 1 counters

还有一个选项可用于检查LACP的接口记帐。

调试
当没有LACP同步或远程对等体不运行LACP时，生成系统日志消息。

使用以下命令启用LACP调试：
debug lacp [event|packet|fsm|misc]
debug condition <condition>
如果发现LACP协商问题，请启用LACP调试以分析原因。
switch#debug lacp event

switch#debug lacp packet
Link Aggregation Control Protocol packet debugging is on
switch#debug lacp fsm
Link Aggregation Control Protocol fsm debugging is on
switch#debug lacp misc

如果需要，还应启用特定接口的调试条件并过滤输出。
switch#debug condition interface gigabitEthernet 1/0/1
验证调试和过滤器已设置。
switch#show debugging

平台工具
下表显示了可用的工具和功能，以帮助了解何时使用它们：
| 工具 |
级别 |
何时使用 |
| EPC |
硬件与软件 |
使用它来验证位于物理接口的LACP帧，或验证它们与CPU的连通性。 |
| 平台前进 |
Hardware |
如果确认了LACP帧已降级到交换机上，请使用此工具了解交换机的内部转发决策。 |
| PSV |
Hardware |
如果确认了LACP帧已降级到交换机上，请使用此工具了解交换机的内部转发决策。 |
| CoPP |
Hardware |
但是，如果从硬件角度将数据包转发到CPU，则在软件(CPU)级别上看不到该数据包。此功能很可能丢弃了硬件和CPU之间路径上的LACP帧。 |
| FED CPU数据包捕获 |
软件 |
使用它来验证LACP帧是否通过正确的队列传送到CPU，还验证CPU是否将LACP帧发送回硬件。 |
注意：使用这些工具只能分析LACP协议，但是，它们也可用于分析PAgP帧。

要调试转发信息并跟踪硬件转发平面中的数据包路径，请使用show platform hardware fed switch <switch number or role> forward interface命令。此命令模拟用户定义的数据包并从硬件转发平面检索转发信息。根据您在此命令中指定的数据包参数，在入口端口上生成数据包。您还可以提供来自PCAP文件中存储的捕获数据包的完整数据包。
本主题仅详细介绍接口转发特定的选项，即show platform hardware fed switch {switch_num|active|standby}forward interface命令提供的选项。
show platform hardware fed switch <switch number or role> forward interface <interface ID> <source mac address> <destination mac address> <protocol number | arp | cos | ipv4 | ipv6 | mpls>
show platform hardware fed switch <switch number or role> forward interface <interface ID> pcap <pcap file name> number <packet number> data
show platform hardware fed switch <switch number or role> forward interface <interface ID> vlan <VLAN ID> <source mac address> <destination mac address> <protocol-number | arp | cos | ipv4 | ipv6 | mpls>
定义平台转发捕获。在这种情况下，将分析CAP.pcap 帧1。
switch#show platform hardware fed switch active forward interface gigabitEthernet 1/0/1 pcap flash:CAP.pcap number 1 data
show forward is running in the background. After completion, syslog will be generated.
平台转发捕获完成后，会显示下一条Syslog消息。

PSV与Platform Forward（平台转发）捕获类似，不同之处在于PSV从符合触发标准的网络中捕获实时入口帧。

控制平面策略器(CoPP)
CoPP基本上是应用于数据平面（硬件）和控制平面(CPU)之间的管道的QoS监察器，以避免高CPU问题。CoPP可以过滤LACP和PAgP帧（如果这些帧超过该功能建立的阈值）。
验证CoPP是否丢弃LACP数据包。

此命令L2控制队列的输出没有丢弃：

它不会超过L2控制队列。当观察到相反情况时，需要捕获控制平面数据包。
FED CPU数据包捕获
如果您已确保在接口级别收到LACP数据包，EPC和ELAM/PSV确认已将LACP帧传送到CPU，并且在CoPP级别未观察到丢包现象，则使用FED CPU数据包捕获工具。
FED CPU数据包捕获会告诉您数据包从硬件传送到CPU的原因，还会告诉您数据包被发送到哪个CPU队列。FED CPU数据包捕获还可以捕获注入硬件的CPU生成的数据包。
