加入三层交换机后，一些老的网卡如NE2000、8029网卡、8039找不到路由器了？

公司由于原有的网络规格不断扩大，已经近300多台机，于是于上个星期增加了一个3550-24-EMI三层交换机，划分为两个网段-VLAN10、VLAN20，VLAN10划分为196.1.1.0网段，IP地址为196.1.1.21，VALN20划分为196.1.2.0网段，ip地址为196.1.2.1，然后各在两边建了一个DHCP服务器动态分配IP地址，采用WINS服务，然后两边同步，现在有两个问题想请教：
1、加入三层交换机后，一些老的网卡如NE2000、8029、8039网卡可以动态分配到IP地址，但是PING三层交换机上层的CX900路由器PING不到，PING VALN10、VLAN20网段的机器正常，运行ORACEL系统也就运行不了!更换网卡为530TX后就一切正常。但是由于这些老网卡机器比较多，如果全部换的话，就不划算，且没有加入三层交换机时一切正常，CX900路由器我没有设置权限，但是3550-24-EMI可以任意设置。
2、划分两个网段后，在网上邻居里VLAN10看不到VLAN20的，VLAN20的看不到VLAN10的，我已经在3550-24-emi上设置了：
vlan10的 ip help-address 196.1.1.8
vlan20的ip help-address 196.1.2.2
然后设置ip forward udp
但是一样看不到，如果希望能够在网上邻居里看到的话，应该怎样设置？

2.WINS服务器之间的复制正常吗？

xiahaifeng

复制正常啊!

东西不是我买的，我只是写方案，价格应该在2万5左右，感觉用起来不错，挺爽，我主要用到它的VLAN和三层路由功能！

你把老网卡的端口speed换成10看一看？

效果一样的！

erjing

那么固定一下端口的mac可以嘛？
你可以show到这些卡的mac地址嘛？
