與Cisco路由器產品線的調試功能類似,Cisco MDS儲存交換機具有光纖通道(FC)分析器來檢查資料包。FC分析器檢查進出交換機提供的實體的資料包。FC分析器能夠對交換機負責接收或傳送到儲存裝置的幀進行調試。FC分析器無法檢查終端站之間的幀。
要檢查會話流,應使用MDS交換機的交換埠分析器(SPAN)功能。與Cisco乙太網路交換器上的SPAN功能類似,MDS產品線上的SPAN會將資料複製到SPAN目的地連線埠,以便第三方裝置可以收集資料。
本文件沒有特定需求。
本文中的資訊係根據以下軟體和硬體版本:
Cisco MDS 9216交換器
Cisco MDS 9509交換器
兩者均運行儲存區域網路作業系統(SAN-OS)1.2.1a。
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。如果您的網路正在作用,請確保您已瞭解任何指令可能造成的影響。
如需文件慣例的詳細資訊,請參閱思科技術提示慣例。
您必須知道何時使用FC Analyzer工具以及何時使用SPAN功能。
FC分析器是一種工具,用於收集發往MDS Supervisor或來自MDS Supervisor的幀。使用此工具可以看到節點到交換機或交換機到交換機的流量。
SPAN是一種功能,允許將暫時連線到交換器的訊框複製到第二個連線埠進行分析。使用此方法可以看到節點到節點的流量。
如需圖示,請參閱下圖:
綠色箭頭表示可使用FC分析器工具進行跟蹤的流量,而粉紅色箭頭表示可使用SPAN方法捕獲的流量。FC分析器無法觀察從主機到儲存的流量。在左側交換機上運行FC analyzer時,只能看到從主機到交換機或從右側的交換機發出的流量。
SPAN可用於追蹤交換器上任何連線埠的進(輸入)和出(輸出)流量。如前面的圖所示,遠端SPAN(RSPAN)可用於收集從左側交換器(分析儀連線到右側交換器)上的主機連線埠進出的訊框。
本節提供用於設定本文件中所述功能的資訊。
注意:要查詢有關本文檔中使用的命令的其他資訊,請使用命令查詢工具(僅限註冊客戶)。
注意:其目的是收集源自9612 Supervisor或發往9612 Supervisor的FC幀。從主機到JBOD的幀不會使用FC分析器工具收集。
FC analyzer local通過控制檯附件或Telnet從命令列介面(CLI)運行。您可以運行一個簡短的顯示以只顯示每個幀的一小部分,或者運行一個詳細的跟蹤以顯示整個幀。
在配置模式下會啟動跟蹤,在按Ctrl-C時跟蹤會停止。預設情況下,僅捕獲100幀。要捕獲100多個幀,請將limit-captured-frames命令選項新增到用於啟動跟蹤的命令中。
也可以使用顯示過濾器將跟蹤的輸出限製為僅特定幀。

按一下停止以停止資料包收集並啟動程式的跟蹤檢視部分。
可以使用過濾器將顯示限製為特定流量流。
如果遠端捕獲啟動出現問題,您可能會看到與下一個影象中的錯誤螢幕相似的錯誤螢幕。FC分析器在MDS上處於非活動狀態,或者在沒有指定埠的情況下使用了active關鍵字。
注意:目的是使用埠1/15上的FC分析器收集9216埠1/16上主機與主機之間的FC幀。
埠1/15上的FC分析器顯示有序集,但不顯示正在SPAN連線的鏈路上發生的有序集。FC分析器裝置可以是埠分析器介面卡(PAA)和運行Ethereal的PC,類似於Finisar裝置。

註:目的是收集9216主機的FC幀(FC分析器連線到9509)。ST介面必須安裝Gigabit介面轉換器(GBIC),且速度必須與9509上的Span目的地(SD)連線埠相符。
嘗試設定RSPAN之前,請確保解決了以下問題:
所有交換機都必須運行MDS代碼1.2或更高版本。
在Span終端(ST)埠中,不應將任何電纜連線到小型可插拔(SFP)。
在開始收集幀之前,請確保FC隧道已啟動。
FC分析器可以是運行Ethereal的PAA和PC,類似於Finisar裝置。
如果SPAN來源和SPAN目的地交換器之間有任何中間交換器,請依照以下程式操作:
在與隧道源和目標相同的子網中建立活動VSAN介面。
啟用IP路由。
啟用FC隧道。
使用SAN-OS 1.2或更高版本。

乙太網埠是銅纜埠,其自動檢測速度為1 Gbps或100 Mbps。必須在PC上安裝Ethereal 0.9(9)或更高版本,以及WinPcap。
FC埠需要SFP和LC到LC電纜才能連線到MDS。
以下是PAA上的交換機設定:
交換機位置從左到右編號為1、2、3和4。
在下一個清單中,1表示dip開關為ON或UP。0表示dip開關已關閉或關閉。
0001 1G NTM 1001 1G ETM 0101 1G STM 0011 1G DTM 0000 2G NTM 1000 2G ETM 0100 2G STM 0010 2G DTM 1111 1G MNM !--- Used for diagnostics only.
開關4指定速度(開= 1G,關= 2G)。 交換機1、2和3指定截斷模式。任何更改都需要重新通電。
以下是模式:
No Truncate Mode(NTM) — 無需修改即可傳遞FC幀。
Ethernet Truncate Mode(ETM) — 將負載大小從528行減少到368行,以將FC幀中繼到最多1496位元組。
Shallow Truncate Mode(STM) — 將負載大小從528行減少到58行,以將FC幀中繼到最多256位元組。
深度截斷模式(DTM) — 將負載大小從528行減少到10行,將FC幀中繼到最多64位元組。
