      Understanding Cisco IOS

      Cisco IOS As you know that Cisco is the worldwide leader in providing the hardware solutions as well as the software solutions of LAN and WAN. The hardware solutions mean that the hardware devices such as switches and routers etc but what is the meaning of software solution? The software solution actually means that Cisco

    • IP Access Lists

      IP Access Lists

      Access lists are used to control and manage access of interesting and non interesting traffic. Access lists are powerful tools for controlling access both to and from network segments. They can filter uninteresting packets and be used to implement security policies. Using the right combination of access lists, network managers will be armed with the

    • LAN Switching and Switch Types

      LAN Switching and Switch Types

      Switches represent the features and technologies that can be used to respond to the requirements in emerging network design. Some basic operations and technologies of switches are as follows: Fast Convergence: Switches stipulate that the network must adapt quickly to network topology changes. Deterministic Paths: Switches provide desirability of a given path to a destination for certain

    • Distance Vector Routing Protocol

      Distance Vector Routing Protocol

      Routing Protocols Whenever different networks connect with each other to communicate and to share the data and resources, it is called internetworking. For internetworking, routers must be used on each network or at backbone to route the packets. To route a packet, a router needs to know: Destination Addresses Sources it can learn from Possible

    • What is EIGRP?

      What is EIGRP?

      Local and international networks require information to be constantly updated in order to properly route communications. Routing protocols were developed in order to help keep information flowing to the proper locations and to maintain network connectivity on both LAN and WAN. The Enhanced Interior Gateway Routing Protocol (EIGRP) is one of the most popular internal

    • Understanding Data Encapsulation

      Understanding Data Encapsulation

      The sending and receiving of data from a source device to the destination device is possible with the help of networking protocols when data encapsulation is used. The data is encapsulated with protocol information at each OSI reference model layer when a host transmits data to another device across a network. Each layer communicates with

      Cisco Network Management

      Cisco Network Management Overview of Network Management Different people may take network management as different meanings. It may be considered as solitary network consultant for monitoring network activity using outdated protocol analyzer. While network management in distributed database environment, managing network nodes for generating real time graphics and auto polling of network devices. There are

    • Spanning Tree Protocol

      Spanning Tree Protocol

      Redundant Topology A Local Area Network may consist of more than one segment. Each segment of the LAN connected through a separate physical device mostly switch. Switches use their uplink ports to connect different segments. The LAN administrator can connect the switches with each other through more than one uplink port using redundant topology. Redundant

    • Ethernet Cabling

      Ethernet Cabling

      Ethernet is a media access method that is specified at the Data Link layer and uses specific Physical layer cabling and signalling techniques. It is important to be able to differentiate between the types of connectors that can be used to connect an Ethernet network together. I'll discuss the different unshielded twisted-pair cabling used today

    • Understanding Frame Relay

      Understanding Frame Relay

      Frame Relay is a protocol for transmitting data over a wide area network (WAN). It was designed to use across ISDN interfaces but it is now used over an assortment of other network interfaces. Once one becomes a master of frame relay design and configuration, it is much easier to obtain a strong understanding of
