access list cisco - the best tutorial

Cisco access list tutorial : The access control lists (ACLs), access list Cisco allow a router to permit or deny packets based on a variety of criteria access list cisco. The ACL is configured in global mode , but it applies at the interface. An access list cisco ACL does not take effect until it is applied specifically to interface with the IP access-group command . Packets can be filtered when entering or leaving an interface. 

If a packet enters or exits an interface with an access list cisco ACL applied, the packet is compared with the criteria of the access list cisco ACL. If the packet matches the first access list cisco ACL line , the "permission " or appropriate action "deny" is taken. If no match is found , we examined the criterion of the second line. Again, if there is a match, that you take appropriate action if a match is found , the third line of the access list cisco ACL compared with the package. 

This approach continues until a match is found , when the access list cisco ACL fails. If there is no match, a default " deny" is carried out , and the package will not be processed . When configuring an  ACL , if not expressly allowed a packet, it will be subject to the implicit denial of the arrival of each access list cisco ACL . This is the default behavior of an access list cisco ACL and can not be changed . 

A standard ACL is concerned with a single factor, the supply of IP packets . The receiver is not considered . Extended ACL provide for each source and the location of the package , and can take into account the port number too. The numerical range used for each is different: Regular use 1-99 access control list ACL ranges from 1300 to 1399 and the lineups used 100-199 and 2000-2699 . 

There are several points worth repeating before beginning to configure common access control list ACL . 

access list cisco ACL Common considering only the IP address must match . 

access list cisco ACL lines that run from floor. If there is no match on the line, the second is executed if no match in the second, third runs , and so on until there is a match , or the finish of the access control list ACL is reached . This process at the bottom of the first plan gives special value in the order lines . 

There is an implicit deny at the end of each access list cisco ACL . If packets are not expressly authorized , are implicitly denied. 

. If the Ethernet interface of Router 3 must accept only packets with a supply network 172.12.12 , the access control list ACL is configured as follows : 

R3#conf t 

R3(config)#access-list 5 permit 172.12.12. …255 

The access list cisco ACL consists of one special express line allows packets to IP address 172.12.12. / 24 offer. The implicit deny this is not configured or realized in the configuration service , refuse all packets that do not match the first line. 

The ACL is then applied to the ethernet0 : 

R3#conf t 

R3(config)#interface e0 

R3(config-if)#ip access-group 5 in 

But before creating the access control list ACL , this is a very good idea to see what other ACL is already running on the router ! To see the ACL that runs on the router , use the show access-list command, cisco access list tutorial : 

R1#show access-list 

Standard IP access list 1 

permit … 

Normal IP access list five 

permit 172.1.1.1 

Normal IP access list 7 

permit 23.3.3.3 

Extended IP access list 100 

permit tcp any any lt www (26 matches) 

permit tcp any any neq telnet (12 matches) 

deny ip any any 

Extended IP access list 105 

deny tcp any any eq www 

deny tcp any any eq telnet 

You use the access list cisco ACLs all the way up the ladder of Cisco certification , and throughout his career. The value of knowing how to create and apply access control list ACLs is paramount, and it all starts with mastering the basics! 

Introducing the Cisco CRS-X Core Router

An announcement of the newsroom showed the introduction of Cisco core router Cisco CRS-X in its widest range of Cisco routers. This is great news for more than 750 service providers and telecommunications organizations worldwide. There are about 10,000 CRS models of the previous generation in circulation as the basis of the network infrastructure. Emissions Data Carrier Routing System X is scheduled for later this year, no exact date.

Why is great news for a company like Verizon?

The cost and energy capacity will greatly improve, leaving more space and the growth of your network infrastructure. The new CRS-X will provide 10 times the capacity of previous generation model CRS-1. We are talking about 400 gigabits per second, with the potential to reach nearly petabit per second with a multi-chassis deployment. These network speeds are brought to life by Cisco technology any port designed for your online business.

This solution is ideal for Verizon customers drip Cisco. The size of the illuminated its infrastructure capacity to grow at an incredible pace network. Scalability has always been a big problem for service providers, such as the Internet continues to attract users, demand will increase and the CRS-X system will be there to support this growth.

What this means for a core network engineer?

As part of the selection of a specific CPAK transceiver short, long or extend the optical range, you can configure each router interface for a single Cisco 100 Gigabit Ethernet port, 2 x 40 or 10 x GE 10 GE. The advantage is that you have modular options without having to replace the hardware, so you can add on costs. I'm sure the CTO like to see cost savings, even at this scale IT project. You can even take advantage of the Cisco nLight technology by implementing a single management system with the Cisco CRS to reduce operating costs and provide a high density of 100 GE scale.

What are Cisco customers have to say about the Cisco CRS-X?

A Comprehensive Guide to Set Passwords on Cisco Routers!

However, safety and maintenance is very important today. When almost all due to the Internet, chances of piracy and security breaches are also increasing. Many IT experts maintain knowledge extraction of confidential information, as it is a professional legal obligation. However, since it is difficult to trust people in a society increasingly immoral, it is prudent to take precautions and avoid unwanted problems.

Speaking CISCO router, do not have a password so that means serious threat to their privacy. No password, extract personal information is as easy as it is when browsing the Internet relaxed and nothing loses its complete and infrastructure network. If you do not have the passwords for Cisco routers, you can allow anyone to make configuration changes they want, and let you go outside your own network.

In two minutes, you can set passwords for their Cisco routers, providing secure router and network infrastructure. With a Cisco router, wither need an Ethernet cable or the console.

Connection Procedure

First connect the Cisco router with a console or Ethernet cable. If the console cable, connect to the console port of the computer. Then, connect to the console port of the Cisco router that says "console" (Cisco 2600 Series Cabling and installation) in blue writing.

It must be connected to the network (LAN), which is usually located on the side of a laptop or the back of a PC Ethernet cable. Then you must be connected to the Ethernet port labeled "Ethernet 0/0" (Cisco 2600 Series Cabling and installation) in the CISCO router.

Configuring port

Proceed to the second step, you must use the console port to access the router CISCO part of Hyper Terminal program. This program comes preinstalled with the Windows operating system. From the Start menu, select "Accessories", "Communications" "All Programs">> and click on the shortcut to the Hyper Terminal.

The values ​​of these ports should be used when requested by the Hyper Terminal:

· Bits per second: 9600

· Data Bits: 8

· Parity: None

· Stop Bits: 1

· Flow Control: None

Alternatively, you can open a command prompt window by selecting "Run" from the Start menu. Type "cmd" in the space provided and press "Enter." At the command prompt, type "telnet" command followed by the IP address of the router. An example of the command line is: C: \ telnet 123.156.204.12.

Using the command

- Before making any changes, enter the privileged mode on the router and use the following command. You must also ensure that the "Router>" is the default router for a Cisco router system.

Router> enable

- Once you enter the enable command, it will change your prompt CISCO router:

Router #

- To enter the CISCO router configuration mode, the following command must be used:

Router # config

- Once you successfully enter the configuration mode, you receive the following message:

"Enter configuration commands, one per line. End with CNTL / Z."

- After entering the CISCO router configuration mode, the following message will be displayed:

Router (config) #

Settings password

- Now you need to set the activation password using the "enable password" password. For example, the password "Changeme2", the command is as follows:

Router (config) # enable password Changeme2

It is very important that you use a solid basis for defining the password enable password. The activation password is a password protected virtual terminal access to the router over a network interface. This password is visible in the router configuration and is not stored encrypted in the CISCO router.

- We now come to the last step to set the password. You must set the enable secret password with the command "enable secret".

For example, "Newpswd4" as the password, the command is:

Router (config) # enable secret Newpswd4

When settings password, you must use a different password for "enable secret" and "enable password". The enable secret password is more secure and encryption enable password. It can see the enable secret password of CISCO router configuration.

It was a very small part of a technical process in the field of Cisco. For more complete technologies, it is necessary to continue the global certifications. These days a lot of college courses related to Cisco CCNA etc. as Cisco CCIE CCNP programs, training is also more or less on demand so you can think of a certification in this field.

This article was written in order to provide technical information to professionals. Amit Kataria, a video editor at Koenig Solutions has developed this informative piece. Koenig is the offshore service provider No. 1 IT training in the world that offers several training programs for students around the world. These include the Cisco training, training in project management, offered by Microsoft, Linux certifications, Oracle programs, etc.
