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 Eth

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

loopback-detect enable

[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！
