At present, in the IP network, the operator's network to provide more services for the purpose, no longer in the form of xDSL to provide users, but directly provide a unified width interface, in some broadband community this form is particularly common. At present, in the broadband community to apply the most in addition to Internet services, more is to provide IPTV applications. In the promotion of IPTV, for the involved access layer switching equipment, the device is generally required to supp

If the DHCP server operating system is WINODWS Server 2003, you can use method one. If the DHCP server operating system is WINODWS Server 2000, you can use method two. Method One 1.

Take a look at the diagram below, L2 switch turns on IGMP snooping,router1 is a remote multicast router that forwards multicast packets with the PIM protocol. PIM, Protocol-Independent Multicast is a family of multicast routing protocols that can provide one-to-many and many-to-many distribution of data over the Internet. The "protocol-independent" part refers to the fact that PIM does not include its own topology discovery mechani

Application examples My school is a student apartment, PC owns about 1000 units. Using DHCP assigned IP address, with 4 C class addresses, the actual number of addresses available is about 1000. Because of the frequent presence of private DHCP servers in the building, a large number of hosts cannot be assigned to legitimate IP addresses, and because a significant number of hosts specify IP addresses, confli

Do I need to enable DHCP for the community or village network? The following is a technical analysis on personal opinions. My personal suggestion is to enable DHCP, but some people ask why China Telecom and China Unicom do not enable DHCP? When DHCP is enabled, you can see that the boot speed is faster. I think there a

Domain Cache detection (DNS cache snooping) technologyIn a corporate network, DNS servers are typically configured to provide domain name resolution services for hosts within the network. These DNS not only resolves their own private domain name, but also recursively, requesting public DNS to resolve third-party domain names, such as baidu.com. To improve performance, it is common to use cached records to record resolved domain names, especially third

switch, users with different source addresses can access resources and control the access permissions of users before and after authentication. To enable DHCP users to obtain IP addresses of different network segments before and after authentication, the DCN switch uses DHCP OPTION82 and DHCP Snooping technologies. Th

Normally if you have a cable modem or DSL, you get your home PC's IP address dynamically assigned from your service provider. if you install a home cable/DSL router between your modem and home network, your PC will most likely get its IP address at boot time from the Home Router instead. you can choose to disable the DHCP server feature on your home router and set up a Linux box as the DHCP server.
