真的纳闷啊，一台3COM 3824 二层交换机配置VLAN遇到的难解问题

rzwrq

在给一台3COM 3824 二层交换机配置VLAN 时，建了三个VLAN：

1 VLAN1 默认VLAN
10 SERVER 服务器组用
20 OFFICE 办公室用

按以前习惯我都先把1-24端口全部从VLAN1先移出，按下面操作：

bri  vlan  modify  remove  1 1:1-1:24

可却是错误一片：

Failed to Remove the untagged port 1:1 from VLAN 1
Failed to Remove the untagged port 1:2 from VLAN 1
Failed to Remove the untagged port 1:3 from VLAN 1
.....
Failed to Remove the untagged port 1:24 from VLAN 1

想了想，会不会不能和3COM三层交换机一样操作，要直接将端口加到其他VLAN去，就试着先把全部端口移到VLAN 10

bri vlan modi add 10 1:1-1:24

却出现如下错误：

ERROR: the last port member of management VLAN could not be deleted.
Failed to Remove the tagged port 1:24 from VLAN 1

再看了下VLAN配置，结果1到23 port已经移到VLAN 10了，24还在VLAN 1, 却自动转为tagged了，后来不管折腾，VLAN 1总是会有问题存在，也无法正常清空，一定会有一个端口存在，难道VLAN 1一定要有一个端口吗，没听过这种说法额，后来也google不少文章，都没发现搜到过这种错误，在此请问下有没有精通3COM机子的专业人士给看看，有没有遇到过这种错误，难道交换机坏了？

google上只搜到3226和3250的PDF文档有对这个错误的一个描述：

VLAN Configuration

■ Every port on the unit must be an untagged
member of a single VLAN. Every port defaults to
being an untagged member of VLAN1. If you add
the port as an untagged member of another VLAN
then this will replace the VLAN1 membership. If
the port is an untagged member of a VLAN other
than 1, then removing membership of this VLAN
will cause the port to return to being an untagged
member of VLAN1. The unit will respond with the
following error if you attempt to remove the
untagged membership of VLAN1:
Failed to delete untagged port 1:2 from VLAN 1

看的人糊涂啊。。

先表示下没配置过那个型号的机器The unit will respond with the following error if you attempt to remove the untagged membership of VLAN1:是说你删除VLAN1中的untagged的端口时就会提示出错，感觉你应该是命令用错了。。。
