交换机为啥要买license？

Posted 2023-04-19

参考链接：华为交换机license

如下文所示，S交换机支持如下几种License。

功能型License

功能型License控制用户对设备某项功能的使用。用户想要使用某受限功能，需要首先获得该功能的授权。

例如用户想要VXLAN的分布式网关功能和BGP EVPN功能，则就需要购买“VXLAN增强功能授权License”。

资源型License

资源型License控制用户对资源项数目的使用。用户想要使用对应资源项，需要首先获得该资源项的授权。

用户根据实际业务需要，可以不选择资源型License，使用产品默认支持的资源；也可以选择购买一个或者多个资源型License，用户可以任意组合，最终获得的资源数目为所有资源型License的资源之和。

根据资源型License控制的资源，可以将资源型License分为软件资源License和硬件资源License。

软件资源License：例如S5700默认支持接入的AP数是16个，如果用户想要扩充AP的接入数量，则就需要购买“WLAN无线接入控制器AP资源授权License”。该License属于软件资源License。

硬件资源License：即RTU License。例如S5732-H24UM2CC的接口速率默认是2.5GE，如果用户想要将接口速率提升到10GE，则就需要购买“2.5GE接口升级到10GE接口RTU授权License”。

参考技术A 用户购买设备后，可以使用设备的基本功能，常规发生以下事项时，需要购买License：
①使用增值特性；
②设备资源扩容。 参考技术B 一般很少有交换机买license的，如果是交换机需要你可以跟经销商问清楚 是那一块需要，什么型号，什么板卡，一般都是AC或者ap买的多。 参考技术C 可以买其他的型号，这个不是指定的，Liecense开元，不是交换机品牌把 参考技术D 不一定非待用它！别的交换机一样！这待看你用在什么设备上了

You can install the license to enable features on your device. For the Cisco Nexus 7000 Series, the license must be installed in the default VDC or admin VDC. A license applies to features in all VDCs and VRFs on the physical device.

If you need to install multiple licenses in any device, be sure to provide unique filenames for each license key file.

If you have a single supervisor module on your Cisco NX-OS device and you replace the supervisor module, you must reinstall the license key file.

If you are currently running with a grace period license to avoid service disruptions when you install your permanent license, do not disable the grace period by using the no license grace-period command. Instead, just install your new license. The license manager will automatically transition from grace licensing to the installed license.

1. Log into the device through the console port of the active supervisor.

2. Perform the installation by using the install license command on the active supervisor module from the device console.

3. (Optional) Back up the license key file.

4. Exit the device console and open a new terminal session to view all license files installed on the device using the show license command.

5. (Optional) Enable licensed features, if necessary, by using the feature feature-name command in global configuration mode. For example, you can enable the BGP feature as follows:

________________________________________

Step 1 Log into the device through the console port of the active supervisor.

Note Only users with the network-admin role can install licenses on Cisco NX-OS devices. For information on user accounts and roles, see the Security Configuration Guide for your platform.

Step 2 Perform the installation by using the install license command on the active supervisor module from the device console.

Installing license ..done

Note If you provide a target name for the license key file, the file is installed with the specified name. Otherwise, the filename specified in the license key file is used to install the license.

Step 3 (Optional) Back up the license key file.

Step 4 Exit the device console and open a new terminal session to view all license files installed on the device using the show license command.

Enterprise.lic:

SERVER this_host ANY

VENDOR cisco

        <PAK></PAK>" SIGN=0CC6E2245FBE

Note If the license meets all guidelines when the install license command is used, all features and modules continue functioning as configured.

You can use the show license brief command to display a list of license files installed on the device.

Enterprise.lic

You can use the show license file command to display information about a specific license file installed on the device.

Enterprise.lic:

SERVER this_host ANY

VENDOR cisco

        <PAK></PAK>" SIGN=0CC6E2245FBE

Step 5 (Optional) Enable licensed features, if necessary, by using the feature feature-name command in global configuration mode. For example, you can enable the BGP feature as follows:

swtich# configure terminal

switch(config)# feature bgp

You can only uninstall a permanent license that is not in use. If you try to delete a permanent license that is currently being used, the software rejects the request and issues an error message.

When you enable a Cisco NX-OS software feature, it can activate a license grace period. Uninstalling an unused license causes the grace period to come into effect. The grace period is counted from the first use of the feature without a license and is reset when a valid license file is installed.

For the Cisco Nexus 7000 Series, you can uninstall a license only from the default VDC (VDC 1).

Only users with the network-admin role can uninstall licenses on Cisco NX-OS devices. For information on user accounts and roles, see the Security Configuration Guide for your platform.

Permanent licenses cannot be uninstalled if they are currently being used. Features turned on by permanent licenses must be disabled before that license is uninstalled.

If you are using an evaluation license and would like to install a new permanent license, you can do so without service disruption and before the evaluation license expires. Removing an evaluation license immediately triggers a grace period without service disruption.

You must disable the features that are related to the feature before uninstalling a license. The delete procedure fails if the license is in use.

Procedure

________________________________________

Step 1 Save your running configuration to a remote server by using the copy command.

Step 2 Display a list of all installed license key files and identify the file to be uninstalled by using the show license brief command. In this example, the file to be uninstalled is the Enterprise.lic file.

Enterprise.lic

Step 3 Disable the features provided by the license to be uninstalled. Use the show license usage vdc-all package-name command to view the enabled features for a specified package.

Application

-----------

bgp

ospf

bgp@2

ospf@2

-----------

Note For the Cisco Nexus 7000 Series, if the feature names in the show license usage vdc-all command output are followed by "@" and a number, that means that the feature is enabled in a nondefault VDC and must be disabled from that VDC. The number after the feature name is the nondefault VDC identifier number. Use the show vdc command and switchto vdc command to reach the nondefault VDC where you can disable the features.

Step 4 Uninstall the Enterprise.lic file by using the clear license filename command, where filename is the name of the installed license key file.

Clearing license Enterprise.lic:

SERVER this_host ANY

VENDOR cisco

Step 5 Continue uninstalling the license by entering y for yes.

Do you want to continue? (y/n) y

Clearing license ..done

The Enterprise.lic license key file is now uninstalled.

If your license is time bound, you must obtain and install an updated license. Contact technical support to request an updated license.

For the Cisco Nexus 7000 Series, you can update the license only from the default VDC (VDC 1).
