IPX/SPX is a protocol suite that is implemented on many corporate internetworks. IPX/SPX was developed to operate in Novell Netware in LAN environment. But today, the IPX/SPX is also used in Microsoft NT, Microsoft XP and Lotus Notes environment along with Vista. IPX/SPX on Cisco IOS The Cisco IOS also provides a wide range of …
Ethernet refers to the family of Local Area Network implementation that was jointly developed by Digital Equipment Corporation, Intel Corporation and Xerox Corporation. It consists of certain specifications and standards as well as hardware devices and components. Ethernet Connection The Ethernet protocol provides for a verity of cabling options, one of which is a specification …
Cisco IOS software is installed in the manageable Cisco switches for better LAN management. It delivers network services and enabled networked applications. The Cisco IOS has a command line interface that helps users to execute the Cisco IOS commands. Cisco Switch Commands The Cisco switch IOS has different EXEC modes with distinctive prompts. These modes …
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 …
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 the Cisco Three-Layer Hierarchical Model Hierachical network design helps us to make networks more reliable and predictable. Level by level design help to understand networking factions easily like, we can use tools like access lists at specific level and can avoid them from others. Cisco layer model consist of the following three layers. The …
Ethernet at the Data Link Layer Ethernet provides services corresponding to Layers 1 and 2 of the OSI reference model, and IEEE 802.3 specifies the physical layer (Layer 1) and the channel-access portion of the Data Link (Layer 2). In addition, IEEE 802.3 does not define a logical link control protocol but does not specify …
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 …
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 …
Cisco Router IOS Cisco routers are manageable devices, which means that they have the Cisco IOS software for network and internetwork management. The Cisco’s IOS software delivers network services and enabled networked applications. The Cisco IOS is the CLI based software with which Cisco IOS commands can be executed. Cisco Commands There are more than …
