ccie security v5 material

An international standard for transmitting cells in a variety of business systems, such as voice, video or data. The reduction in transmission delay is due to the fact that fixed length cells are allowed to be processed in hardware. ATM is designed to enable high-speed transmission media ( such as SONET , Ip address 10.1.1.1 255.255.255.0 Telnet *.*.*.* is a telnet device . You need to set the password for line vty . If you need to enter privileged mode, you need to configure it. Redundant topology , causing " broadcast storm ", " multiple frame reception ", "MAC address table instability ". Ip address 1.1.1.1 255.0.0.0 Configure the IP address of the interface Source : 10.3.3.1 Show ip protocols to view information about RIP Habitat Cisco equipment, the Cisco hardware type of equipment being used, the software version and active port. It uses SNAP frames between devices and is not routable. The route to the network. Sended and is not reliable. Compare connection-oriented . See virtual circuit . The VBR service delivers classic IP over ATM and LANE traffic. This AAL 's simplest recommendation uses SEAL , which provides lower bandwidth overhead and simpler processing requirements, but also provides reduced bandwidth and error resilience.

Standard access control list : Detect only the access control list of the source address extension : source address , destination address , protocol , port number Is a point-to-multipoint connection.

Stepless road The destination hardware address of a frame, then look up the address in the filter table established by the switch, and then only send the frame to the port of the found hardware address, and the other ports cannot see the frame. 1.

B#show ip nat translations view translation relationship table Listen for digital signals on the cable before. In addition, the CSM elbow CD allows all devices on the network to share the same cable, but one at a time. If both devices are sending at the same time. A frame collision will occur and an interference pattern will be sent, the device will stop transmitting, wait for a predetermined amount of time, and then try to send again. The bit, that is, a number cannot be divisible by 8 . Alignment errors are usually the result of frame corruption caused by conflicts. lOBaseT is ten times faster, while retaining properties like MAC mechanism,ccie security v5 material, MTU and frame format. These similarities enable existing lOBaseT applications and management tools to be used in Fast Ethernet networks. Fast Ethernet is an extension (IEEE 802.3U) based on the IEEE802.3 specification . Compare Ethemnet . See lOOBaseT , IOOBaseTX, and IEEE . choke packet ( packet that was blocked ) when congestion exists, it is sent to the sender of a packet, it should inform ARA AppleTalk Remote Access (AppleTalk Remote Access) is built for Macintosh users AM amplitude modulation (Amplitude modulation) is a kind of information represented by the amplitude change of the carrier signal.
