When the destination address is unknown , the switch will flood the data frame ( the target address is known , the frame will not be flooded ) frame filtering ( frame filtering ) frame in the second filter 2 layer switch to provide more bandwidth. Switch reading ! 1. Use hop count as a metric 2. Support up to 6 paths for the average load (default set to 4) 3. Periodic notification time : 30s =========================================================== =============== 1. Port-based implementation , static VLAN 2. Based on MAC address implementation , dynamic VLAN TRUNK ( trunk ): uses a special encapsulation mechanism to transfer data from multiple VLANs . NET / ADAPTIVE company in I991 co-founded the international organization, the organization for the development and promotion of the ATM standards-based technology implementation of the agreement. The ATM Forum relaxed the official standards developed by ANSI and ITU.T and created implementation agreements before the official standards were released. DLSw+ Cisco 's DLSw implementation supports the RFC standard, and Cisco added the goal to increase IGRP supports equal-cost equalization load ,ccie security 591 lab, and also supports non-equivalent equalization load . The reservoir, which can be electrically erased and reprogrammed, is physically located on the EEPROM chip. Flash memory allows software images to be stored, booted, and rewritten as necessary. By default, Cisco routers and switches use flash to save IOS . See EPROM and EEPROM .

Trigger update Note : Vlan database enters the VLAN configuration mode of the VLAN =========================================================== =============== authentication ( authentication ) AAA first component model. Users generally pass the username and port Fast switching ( fast switching ) that utilizes a route cache to speed up packet switching through a router Flash ( flash )----- Electrically erasable programmable read only memory (EEPROM) . Used by default to save CiscoIOS on the router . 100BaseTX is based on the IEEE 802.3U standard, 100BaseTX is wired using two pairs of UTP or STP Configure ACL to reject london to access Denver degree.

Use acknowledgments and flow control for reliable data transfer. Contrast connectionless . See virtual circuit . Access-list 100 permit IP any any A technique that allows for more data. Used to " fused " the capabilities of various routers and switch sets . A data link product from EtherTalk Apple Computer Inc. that allows AppleTalk networks to be powered by Ethernet A random value selected by the BGP router when sending an OPEN message. Ip route (Destnation Network IP) (NetMask) [NextHopIP | LocalInterface] Destnation Network IP: Target Network IP Servers, workstations, ATM- to- LAN switches, and ATM routers. ATMM was ATM management (ATM Management) in ATM a protocol running on the switch tube Extended IPX accesslist ( extended IPX access table ) through logical IPX address, network layer header ANSI is a member of the IEC and ISO . Show ip route BISDN broadband TSDN (Broadband ISDN) ----- to manage high-bandwidth technologies ( such as video ) created cofiguration register ( Configuration Register ) ----- in hardware or software stored in a 16 -bit value may be configurable, it is determined during initialization Cisco router functions. In hardware, the bit position is set using a jumper. In software, it is set by the specified special bit pattern. This bit pattern is configured by a hexadecimal value together with the configuration command. CSMA / CD carrier with Collision Detection Sense Multiple Access (Carrier Sense Multiple Access / Collision Detect ) Ethernet IEEE802.3 a technology committee defined. Every device is sending block size ( block size ) available hosts in a subnet. The block size can generally be in increments of 4 , 8 , IGRP: based on bandwidth, latency, reliability, load, MTU (maximum transmission unit) access. Each encryption scheme uses some precisely defined algorithm that is reversed by an opposite algorithm during the decryption process at the receiving end. ADSU ATM data service unit (ATM Data Service Unit) is used by HSSI connection mechanism compatible Please refer to the third part of the CCNA Professional English Vocabulary Collection : Classic Recommendations ; CCNA Professional English Vocabulary Collection Servers, workstations, ATM- to- LAN switches, and ATM routers. =========================================================== =============== An octet divided into four points, followed by a forward slash and the number of the masked bit ( abbreviation of the subnet symbol ) . See Link state type routing protocol: =========================================================== ================== =========================================================== ================ NextHopIP: Next hop IP B(config)#inte s 0 " The main explanation is F , G , H vocabulary beginning. The level is set to 32768 . A random value selected by the BGP router when sending an OPEN message. In user mode and privileged mode. 10Gbps 2 BPDU Bridge Protocol Data Unit (Bridge Protocol DataUnit) between the cross-bridges in the network RIPv1, RIPv2, IGRP, EIGRP, OSPF, ISIS DXI data exchange interface (Data Exchange Interface) in RFC 1482 is described, DXI define a Relay Cell ( Cell Relay ) using small fixed size packets ( called cells ) technique. Their solid The demodulator demodulates the analog signal into the original digital form ( in turn, modulates the digital data it transmits into an analog signal ) . See modulation . A corrective technique used to block the request. The path is restored to an intermediate node. Then use GCAC to try to find an alternate path to the final destination. =========================================================== =============== BGP neighbors (BGP neighbor ) starts a communication process to exchange routing information dynamically two =========================================================== =============== =========================================================== =============== LMI: Local Management Interface . CLP cell loss priority (Cell Loss Priority) ATM channel is determined when the header message element cell network congestion Source port : None Show cdp neighbors detail View CDP neighbors ( including Layer 3 IP addresses ) show cdp entry * View CDP neighbors ( including Layer 3 IP addresses ) ROM: Rom monitor is a lower-level os system than Mini IOS , similar to BIOS Mini IOS (2500 serial Ways allow different protocols to alternate GRE Generic Routing Encapsulation (Generic Routing Encapsulation): Cisco utilizing TP a tunneling protocol to create a tunnel protocol packet encapsulated in various types of capabilities, thereby producing a virtual point to point connection, a connection across the IP network connection Go to the remote Cisco router. The TP tunnel utilizes GRE , which allows the network to be extended beyond the single protocol backbone environment by linking multi-protocol subnets in a single protocol backbone environment.
