各位大虾,能不能给我意见,还有写出配置代码,很急啊。。
1、用2960做基于端口的VLAN划分,行吗?怎么做呢?
2、用2960做DHCP,行吗? VLAN1不能自动获得IP,VLAN2需要自动获得IP,怎么做呢?
诚心邀请各位发言。

DHCP,当然2811可以做,但是如果不稳定了,你排查起来更麻烦,还不如在VLAN 2中放置一台服务器。
默认情况是不能访问VLAN 1的,除非打开路由,而你的2960是二层交换机,不存在打开路由的问题,所以,默认VLAN 1和2不能互访。除非做好单臂路由。
绑定10以上的MAC,我还真不是特别确定这个事,原来做过4个的,这个Cisco是有数量限制的,忘了多少了,10左右,应该没有问题。呵呵……
祝你好运!

“总的来说,你的要求实现起来没有问题!”见到你的这句话 我很高兴。
回复1、我不需要两个VLAN间的互访,做NAT和路由两个就OK了,谢谢!
回复2、图中的Hub,其实是D-link 1024D 24口交换机,感谢你的建议!
回复3、这个有点麻烦,Files Server应该是属于VLAN1的,我不想VLAN2访问到VLAN1,但是VLAN2需要自动获得IP,如何是好啊?
回复4、应该默认情况下就是不能访问VLAN1的,对吗?
回复5、我是在一个端口上绑定多个(10个以上)主机的MAC地址,能行吗?
关于DHCP,是个大问题哦。。。帮帮。。

总的来说,你的要求实现起来没有问题!
你的需求:
1、2811做好NAT,做好路由,如果需要两个VLAN间的互访,可以配置单臂路由。
2、2960所作的VLAN划分就是基于端口的,这里提出的建议是:将HUB换成其他交换机,哪怕是傻瓜式的。
3、2960不能做DHCP,要做也只能做在2811上。但是做在2811上有时候会非常不稳定。建议是:在服务器群里面单独拿出一台服务器做DHCP服务器。
4、VLAN 2只能上网,不能访问server farm没有问题。
5、MAC地址绑定,没有问题,这也能算是cisco交换机提供的基础安全性能保障之一了。

IP Telephony: Planning, Design, Implementation, Operation, and Optimization
Cisco
IP Telephony: Planning, Design, Implementation, Operation, and Optimization (Kindle Edition)
By Ramesh Kaza, Salman Asadullah

Cisco
Press
Pub Date : February 23, 2005
ISBN : 1-58705-157-5
Pages : 672
The comprehensive guide to planning and implementing your
Cisco
IP Telephony system, as shown by the experts.
Understand how to work through the different implementation phases of a
Cisco
IP telephony solution
Plan your implementation with tools and guides from the most seasoned experts in the industry
Avoid pitfalls in the process with best-practice suggestions and other tips derived from years of actual implementation experience
Cisco
IP Telephony: Planning, Design, Implementation, and Operation of the IP Telephony Network, is a guide for network engineers as they go through the deployment of a
Cisco
IP telephony (IPT) solution. Although an IPT system brings several benefits to an organization, understanding all the components of that system is necessary for a successful implementation. Engineers tasked with implementation must also keep in mind that the architecture they are installing must be scalable in the future. The authors of this book, Ramesh Kaza and Salman Asadullah, have taken an approach to address the questions that come to these engineers while planning, designing, implementing, and operating the
Cisco
IPT solutions. The deployment process has been divided into four phases: Planning, Design, Implementation, and Operation (PDIO). Each phase provides specific details about the tasks involved and best practices for successful implementation of the IPT solution.
This book also contains pre-designed questionnaires and assistance tools that will
help
engineers determine the requirements of each phase of the PDIO cycle. This book is written by experts from
Cisco
with extensive experience in implementing these solutions. Readers are provided step-by-step explanations, specific details, and best practices acquired by the authors while working with the top
Cisco
IPT customers.
