Routers are often used to build wide-area networks, and the footprints of WAN links are very different from those on Ethernet. Common WAN packages are HDLC, PPP, Frame-relay, etc., and this chapter describes HDLC and PPP. PPP, in contrast, has more functions than HDLC.1.1.1 HDLC IntroductionHDLC is a frame-wrapping format on a point-to-page serial line with a very different frame format from the Ethernet frame format, and HDLC has no source Mac and destination MAC addresses.

Whether the switch is in the same domain is distinguished by a domain name, such as the domain name CCIE and the domain name CCIE belong to the same domain, and the domain name CCIE and the domain name Cisco belong to a different domain. The domain name of the default switch is empty, but the most important thing to remember is that if your own domain is empty

Q: Are there any simple tools and methods? Do a script, automatically execute on a script in N-around Cisco switches, and then return the results? Method One, the switch configuration file download, modified and uploaded to the n-switch. Then restart or copy start run. Method Two, under Windows to build a bat file, the contents and you telnet to the switch to modify the command used when the same, but the IP address needs the n times, more trouble.

In recent years, the computer network, especially the Internet development is very rapid, ATM and IP over DWDM technology development so that the network transmission bandwidth quickly increased. While the development of network security and management technology is relatively lagging behind, although the voice of network security is high, but really fall to actually few. It is often believed that increasing the security mechanism of the enterprise network requires the addition of firewalls, aut

The Cisco security solution is based on the ASA 5500 series Adaptive UTM device, which organically integrates security and VPN services with a new adaptive identification and Defense (AIM) architecture. As part of the Self Defense Network, the entire security package provides active threat defense, UTM to prevent attacks before the network is compromised, control network behavior and application traffic, and provide flexible VPN connections.
