coupling between the transmitter (source) at one end of the cable and the loop at the other end, which is obtained from the FEXT (Remote crosstalk) minus the attenuation of the line, this eliminates the impact of cable length. The Return Loss (RSL) is determined by the matching degree of each element in the transmission channel. For 1000BASE-T, only matching connections can meet the demanding RSL requirements. 14. Shared and switched LAN In a LAN, a workstation can use a Media Access Control Pr

, BAS forwards the user identification information to the Radiusv4 server for authentication. After successful authentication, the Radiusv4 server returns the PPP connection parameters and terminal configuration information to the BAS. The BAS forwards the information to the user, and the user terminal uses the information for corresponding configuration, to establish an IPv4 access connection. In the 1483/2684 bridging mode, you can obtain IPv6-related configuration information from the Radiusv

transmission, so that the network has good scalability and scalability. The core of VPN technology is data packet encryption and network transmission. IETF has developed some VPN Technical standards, such as L2 L2TP tunnel technology and L3 IP Sec encryption technology. The promulgation of these two technical standards laid a solid foundation for VPN applications. From the perspective of actual VPN applications, Most VPN services are implemented on the edge of the network, which is transparent

between redundant links using the "uplink link group. Enable the blocked port to skip the listening and learning statuses and directly switch to the forwarding status. PostFast is used to skip the normal Spanning Tree operation on the access layer switch port to speed up the access of the terminal workstation to the network. Its function is to allow the switch port to skip the listening and learning status and directly switch from the blocking status to the forwarding status. This port can only

You can deploy a long-distance/exchange switch of the Lucent soft switch while paying close attention to providing user services in the future. By using the softswitch and the psax concentrator on the network edge, you can provide a VoATM-capable long-distance voice Internet transfer so

Site to site VPN Experiment1.1 descriptionThis experiment uses two routers to test the VPN configuration. Of course, you can also use a PC to a vro, a PC to a VPN concentrator, or a PC to a firewall. All of these support VPN. While we use IPsec VPN in VPN is more secure and reliable.1.1.1. Experiment descriptionWhen preparing an ipsec vpn, follow these steps:1. R1 sends incoming traffic to R2 (sets the incoming traffic to ACL)Ii. R1 and R2 negotiate I

, the use of the collector script can be very convenient to complete the reading of the JSON format file, and the external set of the script has a visual editing debugging environment, the edited script can also be reused (by other reports or programs called). However, if the script has been debugged and does not need to be reused, it would be cumbersome to maintain the consistency of the two files (both the set and report templates), which makes it easier to use the script dataset directly for

This example uses a script dataset to do this:1. Click the "Add" button in the DataSet Settings window to pop up the dataset Type dialo

domain, each domain controller is placed in a different computer room. Remember that the Active Directory is logical, not physical, and allows physical overlap of cables without having to repeat the logical location of the domain. The physical location of the domain controller does not affect the performance of the Active Directory as long as the cable does not exceed the maximum length (twisted pair is 100 m) and there is no repeater, concentrator a
