Smart License

思科啓動了經過構建思科智能軟件管理器門戶來簡化客戶許可管理的計劃。 它能夠幫助客戶瞭解他們購買的許可證以及他們使用的許可證。 其餘各類思科產品已經啓用Smart Enabled，隨着此版本（我這裏學習的版本是Release 8.5）的推出，Smart Licensing如今將在如下平臺上提供：

• Cisco 5520 WLC (AIR-CT5520-K9)

• Cisco 8540 WLC (AIR-CT8540-K9)

• Cisco vWLC (L-AIR-CTVM-5-K9)

• Cisco 3504 WLC (AIR-CT3504-K9) 

咱們須要註冊Smart Account，註冊方式能夠參考：How to Request a Smart Account

 

一、使用Smart Software licensing的限制

• 若是您啓用了思科智能許可證而且控制器已在思科智能賬戶上註冊，咱們建議您執行如下步驟。

  • We recommend you to perform the following procedure if you have the Cisco Smart License enabled and the controller is registered on Cisco Smart Account.

    Perform this procedure before upgrading the controller's boot image.

    1. Deregister the controller running the old build from the Cisco Smart Software Manager (CSSM).

    2. Upgrade the controller with new boot image.

    3. Reregister the upgraded controller with new build on Cisco Smart Software Manager (CSSM).

  • If you try to deregister the controller when CSSM is not reachable, the controller is deregistered internally. This results in a stale entry in CSSM. The workaround for this issue is that you must remove the stale entry from CSSM manually.

  • Token-id that is generated for Cisco 5520 or 8450 WLC cannot be used with Cisco vWLC.

  • Call-Home supports only HTTP and HTTPS mode of communication.

  • Call-Home does not support email mode of communication.

  • After the switch over to Smart Licensing mechanism some of the parameter reports, for example: runtime statistics will not be cumulative reports.

  • To create a new profile and avoid Smart Licensing transport mode from being disabled, ensure that the active profile is disabled using config call-home tac-profile status disable before creating the new profile.

  • Do not use a non-tac profile using call-home data reporting format as this will disable Smart Licensing service
  • There might be a difference in the timestamps when the WLC is in a different time zone, as the WLC is set to local time zone time, whereas the Smart License server is set to UTC time.
  • In a Smart License active HA pair, when the primary WLC stops functioning, and the standby WLC takes over as the new primary, and initiates a reboot. After reboot, the device losses its registration information. Manually registering the device with the Cisco Smart License Manager or rebooting and re-pairing the primary and stand-by devices helps resolve this issue.
  • On a Smart License active HA pair, any attempt to deregister before the switch over to active secondary from active primary is complete, and the renew message is sent, the deregistration process may fail
  • In a Smart License active HA pair, the stand-by device displays evaluation authorization state, this parameter gets updated to display the correct values after the switch over is complete and the WLC is the active controller

  • To free the license on the server in a situation, where the license mechanism is changed to Right To Use (RTU) from Smart Licensing, it is mandatory to manually deregister the device（要在許可證機制從智能許可更改成使用權限（RTU）的狀況下釋放服務器上的許可證，必須手動取消註冊設備）. 

 

 

二、配置Cisco Smart Software Licensing

• 開啓Smart Software Licensing： config licensing smart-license dns-server ip-address
  • 注意：選擇激活licensing機制須要重啓設備！
• 要在設備從新啓動後註冊或取消註冊設備並保留設備註冊狀態，請輸入如下命令： 

  license smart {register | deregister} idtoken

• 查看licensing狀態：show license {status | summary | udi | all}              
  • 注意：Smart License服務與控制器運行異步同步。 所以，在完成同步以前，在執行show命令時，將顯示本地控制器信息，而且當下次調用show命令時，將顯示來自Smart License的更新值。     
• Clear the Cisco Smart Software Licensing statistics：clear stats smart-lic
