There are several types of routers you may hear of:wired router, wireless router. More detailed classification: Internal router (IR): All interfaces belong to the same area; Area Border router (ABR): Interfaces to multiple areas; price cisco 1941 Backbone router (BR): Interfaces to backbone; Autonomous system boundary router (ASBR): Exchange routing info with other autonomous systems; Designated router (DR): Generates link-state info about the subnet; Backup designated router (BDR): Becomes DR if DR fails. If you use computers in your home or office, it is likely that your computer is connected with other computers through some type of router.Like a police officer directing traffic at an interchange, a router will direct or route information, data and files to the locations they need to go.Generally, Routers that we used can either be wired or wireless. A wired router will generally connect to your computer and computers or hardware through an Ethernet cable. This happens with the use of output ports.And the only input port provided on a cisco router 1941 price will be used for the Internet. A wireless router may allow access from several computers through wired Ethernet cables and through wireless connections. cisco 1941 list price You will know the router you are using is wireless if it comes with an antenna. The antenna will provide the router with a specific range that allows other computers in the area with wireless capabilities to access the router, provided they have password access. Two Typical Routers We Usually Used Commercial Router If you have ever been to a coffee shop or hotel that offers Wi-Fi access, chances are they are using a commercial-grade router. These routers are much more powerful than what you would purchase at your local electronics or computer store. The best commercial routers will be able to provide access to the Internet, files and printing, for example, with little problem. Commercial routers may also be used by businesses, hospitals or in a university setting as part of a wide area network or WAN.(Cisco is a leading router manufacturer to aim to provide router and networking solution to small, medium and large enterprises) This is a network that allows computers to connect to each other even if they are in another building across town. The commercial-grade routeur cisco 1941 will be used to connect with the wide area network (WAN) on one side and a smaller network called a local area network (LAN) on the other.The local area network may consist of one large office within a building.In that case, you could have multiple LANs connecting to the WAN through one or multiple routers. Consumer Routers If you are looking for a router for your home or small business, you likely can find what you need at your local electronics store.Generally you will want a router that serves as a wireless access point (WAP).It should also be a network switch.The wireless access point (WAP) basically provides the wireless access that everyone wants.Cisco 1941 k9 That wireless access can be both to the Internet and to other computers in the home or office.Routers that come with a network switch tend to be faster and provide more evenly distributed bandwidth to each port. Consumer routers will come in a variety of price ranges and strengths.Some of the lower priced consumer routers will not have a very strong firewall.

Guide of Cisco ASA 5510 Configuration to Recognize Multiple Public IP Addresses
The Cisco firewall hardware ASA 5510 is a hardware security appliance for enterprise-level computer networks. Among other functions, a Cisco ASA 5510 can operate as a firewall that makes only some hosts behind the firewall visible from the open Internet --- and performs Network Address Translation (NAT) for them. Even if an ASA 5510 has a single network interface on the Internet side, the administrator can still assign multiple public IP addresses to that interface. Each public IP address can get mapped by NAT to a host behind the firewall, or to the configuration interface of the Cisco ASA 5510.

Things You'll Need •	Administrator access to the ASA 5510 •	Console cable for the ASA 5510

cisco security ASA 5510 Configuration to Recognize Multiple Public IP Addresses One. Connect your computer to the ASA 5510 using the console cable. Invoke the terminal emulator on the computer with parameters: + 9600 baud + 8 data bits + no parity + 1 stop bit + no flow control.

Two. Press "Enter" to see the "hostname>" prompt from the ASA 5510. Execute the command "enable" (without quotes) to get into privileged mode. You will have to enter the administrator password.

Three. Enter the configuration commands using the command line, one by one and pressing "Enter" after each one. The "static" configuration command maps external addresses to internal addresses (Static NAT). The concrete sequence of commands depends on your situation. For example, if you want to configure the cisco asa 5510 to use public IP addresses 43.76.91.1 and 45.176.30.74 for internal hosts 192.168.100.1 and 192.168.100.3, respectively, enter these commands: interface Ethernet0/0 nameif outside security-level 0 static (inside,outside) 43.76.91.1 192.168.100.1 static (inside,outside) 45.176.30.74 192.168.100.3 The ASA 5510 is now configured for multiple public IP addresses.

Cisco IOS, Used for Cisco Routers, Cisco Switches and Other Cisco Equipment
What’s the Cisco IOS? Cisco IOS (originally Internetwork Operating System) is the software used on the vast majority of Cisco Systems routers and current Cisco network switches. (Earlier switches ran CatOS.)

IOS is a package of routing, switching, internetworking and telecommunications functions tightly integrated with a multitasking operating system.

The IOS CLI provides a fixed set of multiple-word commands — the set available is determined by the "mode" and the privilege level of the current user. "Global configuration mode" provides commands to change the system's cisco configuration, and "interface configuration mode" provides commands to change the cisco configuration of a specific interface. All commands are assigned a privilege level, from 0 to 15, and can only be accessed by users with the necessary privilege. Through the CLI, the commands available to each privilege level can be defined.

Cisco IOS is versioned using three numbers and some letters, in the general form a.b(c.d)e, where: a is the major version number. b is the minor version number. c is the release number, which begins at one and increments as new releases in the same a.b train are released. d(omitted from general releases) is the interim build number. e (zero, one or two letters) is the release train identifier, such as none (which designates the mainline, see below), T (for Technology), E (for Enterprise), S (for Service provider), XA as a special functionality train, XB as a different special functionality train, etc.

Most Cisco products that run IOS also have one or more "feature sets" or "packages", typically eight packages for Cisco routers and five packages for Cisco network switches. For example, Cisco IOS releases meant for use on Catalyst switches are available as "standard" versions (providing only basic IP routing), "enhanced" versions, which provide full IPv4 routing support, and "advanced IP services" versions, which provide the enhanced features as well as IPv6 support. Each individual package corresponds to one service category, such asIP data, Converged voice and data, Security and VPN.

A&Q about Cisco IOS (from Yahoo Answer) Q: Help needed to upgrade my cisco switch ios? I have connected my switch via console cable, I have set up a tftp server on my PC when I try to update the ios it keeps timing out.

A:First, your computer with the tftp server and the switch need to be connected via the network. When the switch pulls the image, it's not through the console cable, but rather an ethernet port. Second, your new IOS image needs to be in the correct folder on your local hard drive so the tftp server can reach the file and serve it to clients that ask. This varies greatly by tftp server, so I can't give you clear directions for how to do this. Third, your switch needs an IP address assigned to a vlan interface. Typically, vlan 1 is used, but more advanced users can use a different one. The configuration usually looks like: configure terminal interfacevlan 1 ip address w.x.y.z 255.255.255.0 no shut end To do a little troubleshooting, try pinging your computer from the switch and then ping the switch from your computer. Due to firewalls, this may or may not work, but it's a good tool. Lastly, once you are sure that connectivity is in place, you issue the command "copy tftp flash" from the switch. The switch will ask you the IP address of the tftp server, then the filename, and then it will probably ask you if you want to erase the flash. You should usually press "enter" to confirm "yes" to erase the flash, otherwise you'll run out of room in the memory. If you do not receive the question to erase the flash, that means there is a connectivity issue. Hope this helps. Source(s):http://www.cisco.com/en/US/products/hw/switches/ps700

Q: How I can install IOS into cisco switch 3560 series? In my cisco switch 3560 series hasn't IOS system and I cann't into priveleged EXEC mode. "enable" function cann't run!

A: The first thing you need to do is recover the password so you can "enable" privileged mode - you need to "break" as the switch is about to load… 1/ Put the new IOS onto a tftp server (if you don't have one, google for "tftp server free download"). 2/ Get the switch onto the same network as your tftp server. 3/ decide if you have enough room in either flash or RAM (depending on your switch) and copytftp flash …

Cisco IOS Download Tips Generally, if you want to download or upgrade Cisco IOS while having a used Cisco router or didn’t buy Cisco router, options offered here will help you get the Cisco IOS: 1.	Download the Cisco IOS from somewhere like a bit torrent or a file sharing program. 2.	Purchase a maintenance contract for the hardware and download the software. 3.	Buy the IOS from a reseller. (The cost of the software will vary based on the model of the router you are buying it for and the features of the OS you are wanting.)
