最近想將華爲s2300-52p交換機的接口由之前的trunk更改爲access時，總是更改不成功，報錯信息如下：
[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]
無論如何配置，就是不能將端口有trunk改爲access
後面發現這樣配置，就可以將端口更改：
[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通過該端口，然後重新添加默認vlan 1通過，之後就可以更改端口類型了！
