VTP Protocol and its configuration VTP Protocol (VLAN Trunk Protocol) are the role of Cisco private Protocol: from a control point (that is, the server in VTP) maintain the composition of working VTP domains such as adding, deleting, and renaming

The main control functions of the IP layer of the ICMP Control Packet protocol include error control, congestion control, and route control. If an error occurs during IP packet transmission, the IP protocol does not have an internal mechanism to

Use the manual address to configure IPv6 to open the "command prompt ". Type netsh in the command prompt, and then press Enter. Type interface ipv6, and then press Enter. Type add address [interface =] String [address =] IPv6Address, where:

Network Protocol Reading Notes link layer 1, TCP/IP protocol family, the main purpose of the Link Layer: 1) for the IP module to send and accept IP datagram. 2) send ARP requests to the ARP module and receive ARP responses. 3) Send RARP requests to

The Promiscuous Mode of the network adapter is that a machine can receive all the data streams passing through the network adapter, regardless of whether the target address is another one. This is used by network administrators to diagnose network

OSPF protocol troubleshooting 01. How does OSPF prevent routing loops? 1. OSPF in the region adopts the SPF algorithm, and the algorithm itself has no loops. 2. each region is adjacent to the Region 0 to ensure that there is no ring between the

The ospf protocol for layer-3 devices is only suitable for small networks because of the 16-hop limitation of the rip Protocol and other reasons in the information interaction between different network segments. Therefore, ospf protocol has been

Subnet division summary there are a lot of questions about subnet division on the Internet, which is also very detailed, that is, a little too complicated. So here I will make a summary based on my own understanding... The benefits of subnet

The state machine status of the RTSP protocol is for specific objects. Each object is uniquely identified by the rtsp url and session ID. The OPTIONS, ANNOUNCE, DESCRIBE, GET_PARAMETER, and SET_PARAMETER requests do not affect the status of objects

TCP/IP four-click wave ProtocolTCP/IP four-way handshake protocol four-way break-up: Because the tcp connection is full-duplex, each direction must be closed separately. This principle is that when one party completes its data sending task, it can
