最近想将华为s2300-52p交换机的接口由之前的trunk更改为access时，总是更改不成功，报错信息如下：

[ZGK-BG-Ethernet0/0/6]dis this

#

interface Ethernet0/0/6

 port link-type trunk

 port trunk allow-pass vlan 2 to 4094

 loopback-detect enable

#

return

[ZGK-BG-Ethernet0/0/6]port link-t

[ZGK-BG-Ethernet0/0/6]port link-type access

Error: Please renew the default configurations.

... ...

[ZGK-BG-Ethernet0/0/6]undo port link-type trunk

                                          ^

Error:Too many parameters found at ‘^‘ position.

[ZGK-BG-Ethernet0/0/6]undo port link-type

Error: Please renew the default configurations.

[ZGK-BG-Ethernet0/0/6]

    无论如何配置，就是不能将端口有trunk改为access

    后面发现这样配置，就可以将端口更改：

[ZGK-BG-Ethernet0/0/6]dis this

#

interface Ethernet0/0/6

 port link-type trunk

 port trunk allow-pass vlan 2 to 4094

 loopback-detect enable

#

return

[ZGK-BG-Ethernet0/0/6]undo port trunk allow-pass vlan all

Info: This operation may take a few seconds. Please wait for a moment...done.

[ZGK-BG-Ethernet0/0/6]port trunk allow-pass vlan 1

Info: This operation may take a few seconds. Please wait for a moment...done.

[ZGK-BG-Ethernet0/0/6]port link-type access

[ZGK-BG-Ethernet0/0/6]dis this

#

interface Ethernet0/0/6

 port link-type access

 loopback-detect enable

#

return

    成功！

    先去使能所有vlan通过该端口，然后重新添加默认vlan 1通过，之后就可以更改端口类型了！
