解决华为交换机删除vlan时报错：Error: The VLAN has a L3 interface. Please delete it first.

问题描述

当删除交换机的某个vlan时，有时会报错Error: The VLAN has a L3 interface. Please delete it first.

<Server>system-view
Enter system view, return user view with return command.
[~Server]undo vlan 11 
Error: The VLAN has a L3 interface. Please delete it first.

解决办法

1、首先查看该vlanif接口是否绑定了ip地址，若该接口配置了ip地址则使用undo删除

[~Server]interface Vlanif 11
[~Server-Vlanif11]display this 
#
interface Vlanif11
 mtu 9000
 ip address 144.144.1.254 255.255.0.0
#
return

[~Server-Vlanif11]undo ip address 144.144.1.254 255.255.0.0

2、接口没有绑定ip地址后，使用undo命令删除vlan
3、保存配置

<Server>save
