cisco瘦AP降級為胖AP文檔

AIR-LAP1242AG-C-K9, 1242的瘦AP。以1242AP為例,1131和1252做法同樣

1、首先準備回退到胖AP的鏡像檔案。我拿到的是一個 “c1240-k9w7-tar.124-10b.JA3.tar”的tar包壓縮檔案。

2、準備TFTP的環境。(還是用3CDaemon吧,今天曾經用過另外兩個tftp軟體,同樣的條件都無法更新成功。而且3CDaemon還可以随時看到監控記錄,便于分析問題),把目錄指向要更新的鏡像目錄。

TFTP的伺服器主機ip位址設定為10.0.0.2 255.0.0.0 鏡象檔案改名為“c1240-k9w7-tar.default”(IP位址和鏡像檔案名這樣改從後面的提示中可以知道是為什麼)

3、超級終端、控制口連接配接到AP,以便監控狀态。

4、按住ap上的mode鍵,然後插上電源,稍等一會,出現如下提示

flashfs[0]: 3 files, 2 directories

flashfs[0]: 0 orphaned files, 0 orphaned directories

flashfs[0]: Total bytes: 15998976

看到上面wait的提示後,松開mode鍵

button pressed for 29 seconds

process_config_recovery: set IP address and config to default 10.0.0.1

出現上面提示。(從這裡可以看出,在這個狀态下,ap把自己的以太口設定為10.0.0.1的ip位址,然後廣播去找tftp伺服器下的c1240-k9w7-tar.default鏡像檔案)

如果上述設定正确的話,就會開始更新了。

5、更新時的螢幕顯示如下:

6、到此已經可以了,你等着AP啟動完全。你就可以用console口登陸,和配置交換機一樣配置;或者配置一個IP address

interface BVI1

ip address 192.168.1.5 255.255.255.0

no ip route-cache

!

ip default-gateway 192.168.1.254

此時就可以登陸WEB界面經行配置。Cisco預設使用者密碼為Cisco
