Error: Please renew the default configurations.

eNSP实验中出现配置错误当删除命令时，遇到Error: Please renew the default configurations.

经查阅资料发现，需要一层一层的来删除配置，直到恢复到默认的配置，就不再报错误了。

实验环境：

Huawei Versatile Routing Platform Software

VRP (R) software, Version 5.110 (S3700 V200R001C00)

Copyright (c) 2000-2011 HUAWEI TECH CO., LTD

Quidway S3700-26C-HI Routing Switch uptime is 0 week, 0 day, 0 hour, 11 minutes

比如我把配置配错接口了，需要删掉端口的配置

interface GigabitEthernet0/0/1

 port link-type trunk

 undo port trunk allow-pass vlan 1

 port trunk allow-pass vlan 2 to 4094

interface GigabitEthernet0/0/1

undo port link-type trunk

Error: Please renew the default configurations.

正确的删掉命令方式为

interface GigabitEthernet0/0/1

undo port trunk allow-pass vlan all

port trunk allow-pass vlan 1

undo port link-type
