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
the traffic and divide different QoS priorities.
2. CAR Applicability
A car can only work on an IP packet, but cannot limit non-IP traffic. In addition, a CAR can only be used on a vro or vswitch that supports the CEF switch (Cisco Express Forward. Therefore, only models of Cisco 2600 series and above can use CAR. CAR
NAT configuration on a CISCO router is in full swing and causes the shortage of IP addresses. to alleviate this problem, an important application is NAT (Network Address Translation ), it is widely used. Through address translation, NAT enables enterprises to access the Internet by using only a small number of valid IP
RIP and IGRP are commonly used router configuration protocols. What problems should we pay attention to when configuring RIP and IGRP? What should we do? The following configuration steps provide detailed answers.
RIP Protocol
RIP (Routing information Protocol) is an Internal Gateway Protocol (IGP) that is widely used earlier and is suitable for small-sized similar networks, is a typical distance-vector protocol. For more information, see RFC1058 an
Necessity for configuring WRED on a Cisco Router
Although the queue provides VoIP QoS congestion management, it still needs some congestion avoidance mechanisms, such as WRED. In particular, WRED can prevent the output queue from reaching the limit value, which will lead to the loss of all input packets. This article comes from Informit and discusses the necessity of configuring WRED on a
Some time ago, someone familiar with me asked me how to set up a bridge on a Cisco router )? At that time, due to the relationship between work, I just briefly talked to him. Today, we set up a Cisco router as a complete configuration command for bridging. Through this instance, you can learn how to use a

customized within a Network as needed without application. In the network, computers communicate through internal IP addresses. When the internal computer needs to communicate with the external internet, the device with the NAT Function (such as a router) converts an internal IP address to a valid IP address (that is,
Cisco once again launched a new generation of router products and also applied new technologies. So I studied how Cisco developed the new VQE technology to solve the problem of IPTV Video Delivery. Here I will share it with you, I hope it will be useful to you. Cisco has announced the release of the VisualQualityExperi

: single two-way authentication: www.2cto.com 2.2, CHAP authentication: CHAP: Challenge Handshake Authentication Protocol, full name: challenge Handshake Authentication Protocol. 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
