本文說明如何從開機載入器提示和開機模式中復原多層資料中心交換器(MDS)。
為了正常工作,MDS交換機需要有效的未損壞的Kickstart和系統映像才能完全啟動。無效、損壞或缺少Kickstart映像會阻止交換機啟動並在啟動載入程式提示符處停止。具有有效Kickstart映像,但系統映像無效或丟失的交換機最終處於引導模式。
思科建議您瞭解以下主題:
本檔案中的資訊是根據軟體要求版本6.2(9)和更新版本。
本文檔使用的是支援12到48個線速16 Gbps光纖通道埠的MDS9148S交換機switch name tempest。
本文中的資訊是根據特定實驗室環境內的裝置所建立。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。

步驟1.下載交換機的Kickstart和System映像,並將其放入TFTP伺服器目錄中。
在本例中, TFTP伺服器的IP地址為64.104.204.100。
步驟2.配置交換機管理IP地址及其預設網關。
loader> net —ip=10.66.78.80
loader> net —nm=255.255.255.128
loader> net —gw=10.66.78.4
在本例中:
步驟3.測試TFTP伺服器和交換機之間的IP連通性。
從TFTP伺服器ping交換機管理IP地址。
C:\Users\mpandika> ping 10.66.78.80 Pinging 10.66.78.80 with 32 bytes of data: Reply from 10.66.78.80: bytes=32 time=2ms TTL=60 Reply from 10.66.78.80: bytes=32 time=3ms TTL=60 Reply from 10.66.78.80: bytes=32 time=3ms TTL=60 Reply from 10.66.78.80: bytes=32 time=3ms TTL=60 Ping statistics for 10.66.78.80: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 2ms, Maximum = 3ms, Average = 2ms C:\Users\mpandika>
步驟4.啟動位於TFTP伺服器目錄中的Kickstart映像,將交換器進入開機模式。
