Summary of two Cisco S4500 switch configurations

The following are all the problems you will encounter when working through CCIE RS LAB EXAM.
The switchover between the two switches is very simple, the configuration is very simple, but from the beginning of this cut to the final completion, I calculated the time, about two hours, I personally feel that the efficiency is too bad, in fact, should be half Completed within an hour, so special summaries.
The time specified at that time was to change the equipment from 18 o'clock. The original equipment of the customer was an old S4506 switch.
You can see that the engine is a relatively old four-generation engine. There are only two boards on it. I believe many people can see that it is an old GBIC interface, and the fiber is single mode in yellow.
The model of the device that is being replaced now is
From this above, we can see a lot of information, the first is 0X2101, I found out in the summary, I did not update to 0X2102 in the end. Did not pay attention at the time:
This later discovered that it was a very big mistake. It is very likely that it will cause a fallback, but the luck at the time was not bad, and there was no retreat.
Let's take a look at the customer's old configuration:
The following configurations are deleted. The main configuration is as follows:

access-list 101 deny ip 192.168.1.0 0.0.0.255 host 192.168.7.92
access-list 101 deny ip 192.168.2.0 0.0.0.255 host 192.168.7.92

access-list 101 deny ip 192.168.5.0 0.0.0.255 host 192.168.7.92
access-list 101 permit ip any any
Obviously, the configuration is simple and simple. At the time of configuration, when all the configurations were imported into the new switch, the VLANs could not communicate with each other. I was surprised at the time. This is the default, why not here. I remember to manually open the command IP ROUTING. When I hit this command, I remembered that this is the engine of SUP7, and the license is LANBASE. It may not support routing. Because by default, this engine does not buy a license is a Layer 2 switch.
If I follow my own ideas, things will not be configured here, and the cutover work will end here. But this is not the case, but it can be done. In the second layer license, even in the case of lanbase, you can play static routes and support Layer 3 functions. Of course, if it is really not supported, I have written it before, you can use the RTU license, the order will not be repeated in this way.
Here to see the configuration of the new device with the cutover completed:
As can be seen from the figure, the box is the 4507R chassis. Support for dual engines, currently only one engine is configured. WS-X45-SUP7L-E, here again, this engine is usually licensed to send ip base when it is bought, that is, it supports OSPF. But this time did not send, everyone must pay attention when configuring, this time can be configured successfully, there is no fallback, it is because the customer's configuration is too simple, it is not worth mentioning, so it is successful, this is also entirely luck .
The above is my feeling of when I exam CISCO CCIE LAB and CISCO CCIE written exam. Hope you guys for your own dream to fight! Fighting!

What is proxy communication?

Is it correct to understand the working level of forward proxy reverse proxy transparent proxy? Forward proxy and reverse proxy (application load balancing, some NG reverse proxy) can be understood as a man-in-the-middle mode. At the same time, both ends establish a TCP connection, and then the man-in-the-middle performs TCP connection between the two ends. Can a transparent proxy be understood as a simple and crude "hijacking" of a passing data packet, without splitting the complete TCP connection into two independent segments. So, in this sense, this kind of transparent proxy is similar to the working hierarchy of NAT devices? Preface I once saw a person write tens of thousands of words to answer a question, and read it after three days. Shocked, what is all this for? These words can produce a book, and it is also a reward for your hard work. However, I think the man has always been happy, but there is no doubt that his reputation (Reputation) is in full swin

How to choose Cisco dumps?

In this era of lack of trust between people, if you want to buy one thing, in addition to buying on a platform such as a regular platform, such as Amazon. Do you still believe in other self-built platforms? I believe many people have the experience of being cheated. lowest The means of defrauding money is: Your good friend comes to borrow money from you, and you have a relationship card with you so that you can lend him money. At this time, according to the normal person’s thinking, this friend has known me for many years that he might not take the money away. Note that it is often the same idea that gives others the opportunity to owe money. If the amount borrowed is not high, then it is okay. Once the amount you borrowed is too large, you should be careful and your money may not be returned! Back to the topic, in this era of lack of trust, how to choose the Cisco dumps have become an important topic. First, when you buy it depends on whether the website's URL link is https
