这里交换机的设定。

牛X 啊！不错

大家帮忙顶一下，不要让它沉了

DDDD

請問樓主大哥，你的show run是在什麽模式下運行的啊！如何進入這種模式呢？

錘哥，SERVER_ROOM是什麽名字？

这个是交换机的主机名称啊，没有什么特别的，可以自定

哦！我說怎麽和我的不一樣，那路由器的IP爲什麽要設成10.16.10.254呢？這是不是習慣，還是有什麽好處啊

这是网络规划方面的习惯，这样做在大型的网络中比较适合管理。

哦！多谢楼主，请问你把1，2，3口用来做什么？我看怎么和其他的口设置不一样呢？

k看不明白 不过也顶一下

在cisco交换机堆叠时是要使用主干模式连接。在默认情况下，交换机会自动启用trunk模式。第二个端口是我手动trunk起来，对比后发现没有什么差异。

但我看你的2，7，13，16，17全是trunk模式的啊，有哪个必要设这么多的端口么？

考虑到成本问题，全部都是用的２４口。所以就比较多了

哦！郁闷啊，trunk还设的那么零散，再问一下：ip classless 那里设置的是不是允许那些网段可以互访啊？

在旧版本的ios上不支持ip classless，要版本在１１以后的才可以，启用了ip classless会支持子网IP和掩码成对的出现，可以清楚的看出来是哪个子网。

我想问一下楼主，你在交换台里面怎样将VMPS SERVER绑定？可以让交换机自己去到指定的VMPS 服务器上查找TXT文档。。。

哦！我说2950上面怎么没有呢，还有，我看3550上面分了9个vlan，请问3550支持多少个vlan啊，还有我看2950上也设了一个vlan1,请问此vlan1和3550的vlan1有什么不同？因为我只看到其IP不同啊！

嗯！19楼的兄弟问得好啊，请问楼主老大，这个是怎么设的
