Cisco WLCにSSIDを作成する(802.1X/PSK) コマンド編+よくつかうコマンド

Posted at

はじめに

このエントリでは、WLCへのSSID追加をコマンドで実践しています。
GUIでの設定は関連エントリで記載します。

関連するエントリ

Cisco WLCにSSIDを作成する(802.1X/PSK)

対象機器及び環境

  • Cisco virtual Wireless LAN Controller vWLC (Ver.8.2.x)
  • AIR-CAP3502I-Q-K9
  • AIR-LAP1142N-P-K9

ケーススタディ

以下の無線LAN環境をこうちくします。
APの設定は右上にある、APhq01-02F01とします。

AP名は図の通りですが、SSIDは、以下のように記載を変えています。

  • 802.1XのSSID:SSID_DOT1X
  • PSKのSSID:SSID_PSK

実装方法

APモード変更

まず、対象のAPを確認しておきます。
工場出荷状態でWLCに帰属すると、 AP+MACアドレス というAP名になります。

今回対象は APc464.1338.c5a2 です。

※プロンプト省略してます
config ap name APhq01-02F01 APc464.1338.c5a2
config ap mode flexconnect submode none APhq01-02F01

RADIUSサーバの設定

indexを5として設定しています。

※プロンプト省略してます
config radius auth add 5 10.254.10.251 1812 ascii RADIUS_SECRET

WLAN作成

802.1X認証のSSID

indexを11として設定しています。

※プロンプト省略してます
config wlan create 11 SSID_DOT1X SSID_DOT1X
config wlan radio 11 802.11a-only
config wlan broadcast-ssid disable 11
config wlan session-timeout 11 0
config wlan radius_server auth add 11 5
config wlan enable 11

PSK認証のSSID

APグループ、FlexConnectグループには含めませんが、SSID作成、ということで記載しています。
indexを12として設定しています。

※プロンプト省略してます
config wlan create 12 SSID_PSK SSID_PSK
config wlan security wpa akm 802.1x disable 12
config wlan security wpa akm psk enable 12
config wlan security wpa akm psk set-key ascii SSID_PSK_TEST_PASS_PHRASE 12
config wlan radio 12 802.11ag
config wlan broadcast-ssid disable 12
config wlan enable 12

APグループ設定

※プロンプト省略してます
config wlan apgroup add APG_hq01_02F APG_hq01_02F
config wlan apgroup interface-mapping add APG_hq01_02F 11 management
config ap group-name APG_hq01_02F APhq01-02F01

Changing the AP's group name will cause the AP to reboot.

IOSでいう、term len 0みたいなの

config paging disable

 
コマンド出力結果のフィルタ
grep抽出ができます。
IOSでいう、 | include STRING みたいなの
たとえば、特定WLANから、WPAという文字列とCipherという文字列を抽出するときは、

(Cisco Controller) >grep include Cipher|WPA "show wlan 12"
Press any key to continue..
   Wi-Fi Protected Access (WPA/WPA2)............. Enabled

      WPA2 (RSN IE).............................. Enabled
         TKIP Cipher............................. Disabled
         AES Cipher.............................. Enabled

There are 5 lines matching the pattern Cipher|WPA

感想

CLIでの操作は、マニュアル作成時にGUIよりもはるかに記述量が少なくてすみますし、コンフィグの事前チェックや設定変更時の操作ミスも少ないですし、操作履歴もとっておける!
ので、個人的にはCLIによる運用のほうが好きです。
