  • Used to communicate IP status and error messages between hosts and routers Uses IP to route its messages between hosts Must be implemented with IP remember, IP is just a packet delivery system transmits and routes datagrams from sources to destinations through a series of interconnected networks it has a checksum in the IP header to detect lost bits no error detection on the datagram payload though but has no native mechanism for source host notification This is where ICMP comes in its used to report IP errors to the source host ICMP data is carried as the payload of an IP datagram specifie...

  • This book is for anyone who wants to master Linux from the command line. When writing it, I had in mind system administrators, software developers, and enthusiastic users who want to get things going from the Linux command line. For beginning users, this may be a daunting task, as Linux commands often have many options documented only in man pages that are not that easy to understand.

  • I know it’s kind of wrong to say this type of stuff about your own stuff, but I’m just going to do it—this is a really good book! It might even be the most interesting book I’ve written so far. A big reason for this is that its scope allowed me to go above and beyond covering the usual CCNA study guide material and really detail the commands I used in the guide, plus a lot of additional commands that just happen to be some of my personal favorites. Do remember that, although very cool indeed, this volume isn’t intended to be a one-stop shop for...

  • CDP discovers and shows information about directly connected Cisco devices, including routers and switches. CDP is a Cisco proprietary protocol that runs at the data link layer of the OSI model. The data link layer is Layer 2 of the OSI model. This allows devices that may be running different network Layer 3 protocols, such as IP or IPX, to learn about each other. CDP begins automatically upon a device system startup. However, if Cisco IOS Release 10.3 or a newer version is used, CDP must be enabled on each of the device interfaces. Enable CDP by using the cdp enable command.

  • This lab helps the student become familiar with the router show commands. The show commands are the most important information-gathering commands available for the router. • show running-config (or show run) is probably the single most valuable command to help determine the current status of a router, because it displays the active configuration file running in RAM. • show startup-config (or show start) displays the backup configuration file that is stored in non-volatile RAM (NVRAM).

  • Q: Are pings forwarded by routers? A: Yes! This is why you can ping devices all over the Internet. Q: Do all devices forward or respond to pings? A: No, this is up to the network administrator of the device. Devices, including routers, can be configured not to reply to pings (ICMP echo requests). This is why you may not always be able to ping a device. Also, routers can be configured not to forward pings destined for other devices.

  • Multiprotocol Label Switching Multiprotocol Label Switching (MPLS) is a standards-approved technology for speeding up network traffic flow and making it easier to manage. MPLS involves setting up a specific path for a given sequence of packets, identified by a label put in each packet, thus saving the time needed for a router to look up the address to the next node to forward the packet to. MPLS is called multiprotocol because it works with the Internet Protocol (IP), Asynchronous Transport Mode (ATM), and frame relay network protocols....

  • One of the most important aspects of getting a Red Hat Linux system up and running is configuring the user interface. For most nonadministrative users, this means configuring the X Window interface. The X Window System is the Linux graphical user interface (GUI). While the GUI plays an integral part of other operating systems such as Microsoft Windows, the X Window System on Linux is essentially just another application. Many administrators don’t even bother with the GUI; the command line interface is enough for most administrative purposes....

  • Ethernet-based data services offer the opportunity to create differentiation, command premium pricing, and earn higher margins for such value-added data services as transparent LANs, storage area networks, and virtual private networks. Extending native 10/100Base-T and Gigabit Ethernet services across the LAN, WAN, and MAN means data services are less expensive to deploy, provision quickly, and offer exceptional reliability and security.
