目前思科WLC的版本已經在8.x的版本都有很多較高的版本了，例如8.3、8.5，甚至到8.10的版本。雖然Release 7.x的版本已經不值得推薦，但是可能現網中還會存在一些比較老的設備，運行着7.x的版本，這里主要記錄在7.x版本的WLC修改SSID的時候遇到的問題。
1、這里是我們再Release7.4.121版本查看WLAN General信息。
如上圖所示，可以很直觀的看到Profile Name和SSID無法修改，這個時候我們可能會在Release 7.4的配置文檔中查詢是否可以通過CLI來直接修改：
坑人的是，在Release 7.4的配置文檔中，就恰好給了是可以配置的：
Editing WLAN SSID or Profile Name for WLANs (CLI)
-
Edit a profile name or SSID associated to a WLAN:
-
Disable the WLAN first before changing the profile name or SSID by entering this command:
config wlan disable wlan_id
-
Rename the WLAN profile name or SSID by entering this command:
config wlan ssid wlan_id ssid
config wlan profile wlan_id profile-name
-
-
View the WLANs configured on the controller by entering this command:
show wlan summary
Viewing WLANs (CLI)
-
View the list of existing WLANs and to see whether they are enabled or disabled by entering this command:
show wlan summary

這里就值得實際驗證一下了（這里是在7.4.121版本的測試信息），我們無法看到有config wlan ssid命令和config wlan profile命令。
(Cisco Controller) >config wlan enable 1 (Cisco Controller) >show sysinfo Manufacturer's Name.............................. Cisco Systems Inc. Product Name.....................................

這里可以說明：思科Release 7.4的配置文檔中描述錯誤，Release 7.4還不支持修改！但是文檔中給出了命令。
2、關於config wlan ssid
該命令可以查詢到是在Release 8.0才首次出現，具體可以參考command guide
config wlan ssid
To edit an SSID associated to a WLAN, use the config wlan ssid command.
config wlan ssid wlan_id ssid
Syntax Description
| wlan_id |

3、config wlan ssid測試
該測試是在WLC 8.3.150的版本測試。可以看到不同的效果（無論是GUI還是CLI）
如上可以看到是可以直接修改。在CLI界面，我們也可以直接配置：
(Cisco Controller) >show sysinfo Manufacturer's Name.............................. Cisco Systems Inc. Product Name..................................... Cisco Controller Product Version.................................. 8.3.150.0 RTOS Version..................................... 8.3.150.0 Bootloader Version............................... 8.3.15.96 Emergency Image Version.......................... 8.3.150.0 OUI File Update Time.............................

System ObjectID.................................. 1.3.6.1.4.1.9.1.1631 <snip> (Cisco Controller) >show wlan summary Number of WLANs.................................. 1 WLAN ID WLAN Profile Name / SSID Status Interface Name ------- ------------------------------------- -------- -------------------- 1 OK1 / OK1 Enabled management (Cisco Controller) >config wlan disable 1 (Cisco Controller) >config wlan ssid 1 OK SSID Updated successfully. (Cisco Controller) >config wlan profile 1 OK (Cisco Controller) >
如此，便得到進一步的驗證。
