排除Catalyst 9000交換機上的EtherChannel故障
簡介
本檔案介紹如何瞭解Catalyst 9000系列交換器上的EtherChannel並對其進行疑難排解。
必要條件
需求
思科建議您瞭解以下主題：
- Catalyst 9000系列交換器架構
- Cisco IOS® XE軟體架構
- 連結彙總控制通訊協定(LACP)和連線埠彙總通訊協定(PAgP)
採用元件
本檔案中的資訊是根據以下硬體版本：
- Catalyst 9200
- Catalyst 9300
- Catalyst 9400
- Catalyst 9500
- Catalyst 9600
本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。
背景資訊
有關限制、限制、配置選項和注意事項的最新資訊，以及有關此功能的任何其他相關詳細資訊，請參閱思科官方發行說明和配置指南。
EtherChannel在交換機、路由器和伺服器之間提供容錯高速鏈路。 使用EtherChannel增加裝置之間的頻寬，並將其部署到網路中可能發生瓶頸的任何位置。EtherChannel為鏈路丟失提供自動恢復，它將負載重新分配到其餘鏈路。如果鏈路發生故障，EtherChannel會將來自故障鏈路的流量重定向到通道中的其餘鏈路，無需干預。
可以配置EtherChannel，無需協商，也可以透過鏈路聚合協定（PAgP或LACP）的支援進行動態協商。
啟用PAgP或LACP後，交換機將瞭解合作夥伴的身份和每個介面的功能。然後，交換機將具有類似配置的介面動態分組為單個邏輯鏈路（通道或聚合埠）；交換機將這些介面組基於硬體、管理和埠引數限制。
LACP標誌
LACP標誌用於在埠通道啟動時協商埠通道引數。看看每面旗子的意義：
| 旗標 |
狀態 |
| LACP活動（低有效位） |
0 =被動模式 1 =活動模式 |
| LACP超時：指示LACP傳送/接收超時 |
0 =長超時。3 x 30秒（預設） 1 =短超時。3 x 1秒（LACP速率快） |
| 彙總 |
0 =單個鏈路（不考慮聚合） 1 =可聚合（潛在的聚合候選對象） |
| 同步 |
0 =鏈路不同步（非良好狀態） 1 =鏈路處於同步狀態（正常狀態） |
| 正在收集 |
0 =尚未準備好接收/處理幀 1 =準備接收/處理幀 |
| 分佈 |
0 =尚未準備好傳送/傳輸幀 1 =準備傳送/傳輸幀 |
| 已預設 |
0 =使用收到的PDU中的資訊給合作夥伴 1 =它使用合作夥伴的預設資訊 |
| 已過期（最高有效位） |
0 = PDU已過期， 1 = PDU有效 |
LACP標誌的預期值是0x3D （十六進位制）或0111101 （二進位制），以達到P （捆綁在埠通道中）狀態。
.... ...1 = LACP Activity (less significant bit)
.... ..0. = LACP Timeout
.... .1.. = Aggregation
.... 1... = Synchronization
...1 .... = Collecting
..1. .... = Distributing
.0.. .... = Defaulted
0... .... = Expired (most significant bit)

檢驗LACP的運行情況
本節介紹如何驗證LACP協定的正確狀態和操作。
基本檢查
使用以下命令檢查LACP輸出：
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>
第一個命令輸出顯示交換機系統ID及其優先順序（對於LACP）。
switch#show lacp sys-id
32768, f04a.0206.1900 <-- Your system MAC address
檢查LACP鄰居的詳細資訊，如運行模式、鄰居系統Dev ID及其優先順序。
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

Gi1/0/4 SA 32768 f04a.0205.d600 24s 0x0 0x1 0x105 0x3D <-- Dev ID: Neighbor MAC Address
驗證每個介面傳送和接收的LACP資料包。如果檢測到損壞的LACP資料包，則Pkts Err計數器會增加。
switch#show lacp 1 counters

調試
如果沒有LACP同步，或者遠端對等體不運行LACP，則會生成系統日誌消息。
%ETC-5-L3DONTBNDL2: Gig1/0/1 suspended: LACP currently not enabled on the remote port. %ETC-5-L3DONTBNDL2: Gig/1/0/1 suspended: LACP currently not enabled on the remote port.
使用以下命令啟用LACP調試：
debug lacp [event|packet|fsm|misc]
debug condition <condition>
如果發現LACP協商問題，請啟用LACP調試以分析原因。
switch#debug lacp event
Link Aggregation Control Protocol events debugging is on
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，還應啟用特定介面的調試條件並過濾輸出。
switch#debug condition interface gigabitEthernet 1/0/1
驗證調試和過濾器已設定。
switch#show debugging

平台工具
下表顯示哪些工具和功能可用於幫助瞭解何時使用它們：
| 工具 |
層級 |
使用時機 |
| EPC |
硬體和軟體 |
使用它來驗證位於物理介面的LACP幀，或驗證它們與CPU之間的連線。 |
| 平台向前 |
硬體 |
如果確認交換機上的LACP幀已著陸，請使用此工具瞭解交換機的內部轉發決策。 |
| PSV |
硬體 |
如果確認交換機上的LACP幀已著陸，請使用此工具瞭解交換機的內部轉發決策。 |
| CoPP |
硬體 |
但是，如果從硬體角度將資料包轉發到CPU，則在軟體(CPU)級別上看不到該資料包。此功能很可能在硬體和CPU之間的路徑上丟棄LACP幀。 |
| FED CPU資料包捕獲 |
軟體 |
使用它來驗證LACP幀是否透過正確的隊列傳送到CPU，它還驗證CPU是否將LACP幀傳送回硬體。 |
注意：使用這些工具只能分析LACP協定，但是，它們也可用於分析PAgP幀。

要調試轉發資訊並跟蹤硬體轉發平面中的資料包路徑，請使用show platform hardware fed switch <switch number or role> forward interface命令。此命令模擬使用者定義的包，並從硬體轉發平面檢索轉發資訊。入口連線埠上會根據您在此命令中指定的封包引數產生封包。您還可以從儲存在PCAP檔案中的捕獲資料包中提供完整的資料包。
本主題僅詳細介紹介面轉發特定的選項，即show platform hardware fed switch {switch_num|active|standby}forward interface命令提供的選項。
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>
定義平台轉發捕獲。在這種情況下，將分析CAP.pcap 幀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.

控制平面管制器(CoPP)
CoPP基本上是應用於資料平面（硬體）和控制平面(CPU)之間的管道的QoS監察器，以避免高CPU問題。如果這些幀超過功能建立的閾值，CoPP可以過濾LACP和PAgP幀。
驗證CoPP是否丟棄LACP資料包。

它不會超過L2控制隊列。當觀察到相反的情況時，需要捕獲控制平面資料包。
FED CPU資料包捕獲
如果您已確保在介面級別收到LACP資料包，EPC和ELAM/PSV確認LACP幀被傳送到CPU，在CoPP級別沒有觀察到丟包現象，則使用FED CPU資料包捕獲工具。
FED CPU資料包捕獲告訴您資料包從硬體傳送到CPU的原因，它還告訴您資料包被傳送到哪個CPU隊列。FED CPU資料包捕獲還可以捕獲注入硬體的CPU生成的資料包。
