Configure PPPoE for connecting a CISCO router to an ADSL modem using
for Cisco IOS software. IOS is usually stored in flash memory, but may also be stored in other locations, such as TFTP (simple File Transfer Protocol) servers. If the complete IOS image cannot be found, the lite version of IOS will be copied from ROM to RAM. This version of IOS is generally used to help diagnose problems, or to load the full version of IOS to RAM. Note: The TFTP server is usually used as the backup server for IOS, but can also serve

This article describes in detail how to skillfully set the speed limit for commonly used Cisco routers, and provides detailed operation steps. I hope this article will help you.
The so-called speed limit is to set the ACL Access Control List on the router) to block the port used by the Service, so as to prevent the normal operation of the service. For the btsoftware, we can try to seal its port. In general,

CHAP verifies the identity of the authenticated end through a three-way handshake. It is completed when the initial link is established. To improve security, it is periodically verified after the link is established. CHAP is safer than PAP because CHAP does not send plain text online, but instead sends a random number s

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
supports SSH. log on to your vro or vswitch and check whether you have loaded an IPSec IOS image that supports SSH.
In our example, we will use the Cisco IOS command. Run the following command:
Router> Show flash
This command displays the name of the loaded IOS image. You can use the result to compare the list of supported features of your supplier.
After you verify that your device supports SSH, make sure
