升级 3850

發布時間：2025/3/15 编程问答 35 豆豆

生活随笔收集整理的這篇文章主要介紹了升级 3850 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

在本文中，我們將了解如何配置Cisco3850交換機以實現基本無線連接。這是Converged Access產品平臺的一部分，您應該對新架構有一定的了解（本文不會討論）。這里是使用3850作為WLC時需要記住的幾個關鍵點。

1.?You have to attach your access points directly to your 3850 switches?(yes, every wiring closet you should have this in order to all building AP to be connect to this new environment)

1.您必須將AP直接連接到3850交換機（是的，您應該有各個配線間，以便所有建筑物的AP連接到這個新環境）

2.?Wireless management vlan & AP management vlan should be identical. If you configure vlan 21 as wireless management in 3850 switch all your APs connected to this switch should be on access vlan 21.

2.無線管理vlan和AP管理vlan應該是相同的。如果在3850交換機中將vlan 21配置為無線管理，則連接到此交換機的所有AP都應在vlan 21上被訪問。

3.?You need to have Mobility Controller (MC) functionality in your network?(MC functionality can be in the same 3850 switch, another 3850 switch or 5508/5760 centralized controller). By default, when you enable wireless management, switch will act as Mobility Agent (MA) & not able to register an AP without a MC since license are reside on MC.

3.您需要在網絡中具有移動控制器（MC）功能（MC功能可以在同一個3850交換機，另一個3850交換機或5508/5760集中控制器中）。默認情況下，當您啟用無線管理時，交換機將充當移動代理（MA）并且無法在沒有MC的情況下注冊AP，因為許可證駐留在MC上。

4.“ipbase” or “ipservices” feature set to be there for MC functionality.”lanbase” cannot be used for MC functionality switch stack.

4.“ipbase”或“ip services”鏡像可設置為MC工作。“lanbase”不能用于MC功能工作，switch stack。

5.?Given 3850 switch stack can support maximum 50 APs.

5.鑒于3850交換機堆棧可以支持最多50個AP。

In my lab setup I have two 3850 switches stacked together. Before getting started, we will ensure we will have latest software code on this switch. At the time of this write up, IOS-XE 3.2.3SE is the latest code available for this 3850 platform. You can refer?3850 IOS-XE 3.2.x SE release note?for more details of the features/restrictions/etc.

在我的實驗室設置中，我將兩個3850交換機堆疊在一起。在開始之前，我們將確保在此交換機上有最新的軟件代碼。在撰寫本文時，IOS-XE 3.2.3SE是此3850平臺的最新代碼。有關功能/限制/等的更多詳細信息，請參閱3850 IOS-XE 3.2.x SE發行說明。

我們將新的鏡像copy到3850的flash上：

3850-1#copy tftp://192.168.20.51/firmware/cat3k_caa-universalk9.SPA.03.02.03.SE.150-1.EX3.bin flash: Destination filename [cat3k_caa-universalk9.SPA.03.02.03.SE.150-1.EX3.bin]? Accessing tftp://192.168.20.51/firmware/cat3k_caa-universalk9.SPA.03.02.03.SE.150-1.EX3.bin...

[OK - 223743040 bytes]

There are two modes called “INSTALL” & “BUNDLE” available in these new switches. If you want to boot in “INSTALL” mode you have to copy the image onto flash first. In “BUNDLE” mode, you can still? keep the image on TFTP & boot from there if required. But in BUNDLE mode switch require more memory to do this function & preferred method is do it via “INSTALL” mode.

You can use “software install file <file_location>?” command to install new software onto your switch. At the end it will prompt to reload the switch as shown below.

Now if you look at your contents of your flash directory you will see multiple .pkg files .conf files. Depending on the image came with your switch & how many time you upgraded the switch, there could be multiple versions of the .conf files & .pkg files. You can clean this directory using “software?clean” command which will result deleting all unwanted file from your directory. In this way you will only keep 3.2.3SE related files on your flash.

You can verify switch is having upgraded image in each member of the switch stack.

3850-1#sh ver | be SW Switch Ports Model????????????? SW Version??????? SW Image????????????? Mode? ? ------ ----- -----????????????? ----------??????? ----------??????????? ----? ?1 56???

You can verify boot configuration of your switch using “show boot” CLI command. As you can see “packages.conf” file is the boot loading file used in the booting process. If this file is not exist or corrupted switch will go onto ROMMON mode.

您可以使用“show boot”CLI命令驗證交換機的引導配置。如您所見，“packages.conf”文件是引導過程中使用的引導加載文件。如果此文件不存在或損壞，則交換機將進入ROMMON模式。

3850-1#sh boot --------------------------- Switch 1 --------------------------- Current Boot Variables: BOOT variable = flash:packages.conf;Boot Variables on next reload: BOOT variable = flash:packages.conf; Manual Boot = no Enable Break = no

You can access wireless controller GUI using?https://<switch-ipaddress>/wireless?URL.

It is different look & feel compare to CUWN controllers (5508,2504, etc). Let’s see how we can configure the wireless controller config on this switch. First of all you need to ensure you have the correct license to start with.
