足迹IT大神们请进

richsea

网上看到有人说笔记本网卡可以支持trunk，和交换机的trunk口互联，不知道有哪位做过么？

我的配置，intel82557LM网卡，cisco 3550ps-s交换机

知道足迹牛人多，请不吝指教，谢谢

有什么用？ 笔记本做 router on a stick ?

richsea

假如我电脑里有多台虚拟服务器的网卡在不同的VLAN，这样就可以模拟一个比较大的网络拓扑了

在同一个lan配不同的 ip subnet不是也可以达到这个要求？

richsea

这样抓包会有问题，所有的包都被抓进来了

其实最主要的是想实现GNS3或者VMware里的router或者fw的接口上支持trunk，和物理交换机通讯

Intel lan card will strip off VLAN tag by default, follow this and it will work

For Microsoft Windows*

Allow tagged frames to be passed to your packet capture software by going into the registry and either add a registry dword and value or change the value of the registry key. The bus type of your network adapter you dictate the keyword used, either "MonitorModeEnabled" for PCI/PCI-X Network Adapters, or "MonitorMode" for PCI-e based Network Adapters.
The new key (dword) should be placed at:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\00nn
Where nn is the instance of the network adapter that you need to see tags on. (Check by opening and viewing the name of the adapter.)

The registry dword for a PCI or PCI-X Network Adapter is: MonitorModeEnabled.
Set the dword value to one of the following options:

0 - disabled (Do not store bad packets, Do not store CRCs, Strip 802.1Q vlan tags)
1 - enabled (Store bad packets. Store CRCs. Do not strip 802.1Q vlan tags)
The registry dword for a PCI-Express Network Adapter the registry dword is: MonitorMode.
Set the dword value to one of the following options:

0 - disabled (Do not store bad packets, Do not store CRCs, Strip 802.1Q vlan tags)
1 - enabled (Receive bad/runt/invalid CRC packets. Leave CRCs attached to the packets. Strip VLAN tags and ignore packets sent to other VLANs as per normal operation.)
2 - enabled strip vlan (Receive bad/runt/invalid CRC packets. Leave CRCs attached to the packets. Pass all VLAN packets to the host, even those sent to other VLANs. Leave VLAN tags attached to the packets. This mode is likely to break VLAN)

我是用vmware vlan-tag interface--intel PRO/100 S Server adapter(PC)--cisco1841
不过目前还不太成功，可能是crossover cable的问题。

你的问题我同求。

研究中，有结果再来汇报

这个好像是要交换机支持，而且也需要你的网卡支持。。

不想在这上面浪费时间了，搞了几个USB to RJ45，搞定
