How to Save the Cisco 3560 Switch Configuration

Connect to the Switch

1. Plug your computer into the switch with a rollover cable. This cable has a RJ-45 jack on one end and a serial connection on the other. Plug the RJ-45 end into the "CONSOLE" port of the switch, and the serial end into your computer.

2. Download and install a terminal program called PuTTY to connect to the switch (see Resources).

3. Open the terminal emulation software. In PuTTY, select "Serial" in the "Category" box on the left, then select the correct COM port in the "Serial line to connect to" box. Click "Open" to open the command line of the switch. The command line is a text-based interface for the switch. cisco 3560 second hand It has a prompt where you can enter commands to change settings and configurations.

Save the Configuration

1. Type "enable" at the command line, then press return on the keyboard to enter into "privileged exec mode." The switch prompt should change from "Switch>" to "Switch#, then you can enter the next command.

2. Type "copy running-config startup-config" at the command line and press return on the keyboard. This will copy the current switch configuration to the non-volatile memory, which is memory that will retain its data even without power applied to it.

3. Type "show running-config" to display the current configuration.

4. Click and hold at the beginning of the output from the "show running-config" command, then drag down to the bottom of the PuTTY window. This should select all the text on the screen.

DoS Protection on Cisco 7600 Routers

The Cisco router is one of the most versatile High End routing machines. It is one of enterprise’s networking devices. If you take a look at Cisco website under the Routers Product Category, you will notice that the Cisco 7600 can be used in Data Centers, in Service Provider networks, in WAN aggregation or as Internet Edge router. In Service Providers can be used as Provider Edge (PE) in IP MPLS networks aggregating many Customer Edge (CE) router devices. Its modularity and high port capacity allows the 7600 to work as both Layer2 aggregation and as Layer3 high performance router.

In Service Provider networks one of the main concerns of network administrators is to protect the networking infrastructure from Denial of Service attacks. These DoS attacks are actually the most serious and popular security threat against Service Providers. buy used router Botnets are frequently the main source of such attacks. ICMP flooding, UDP flooding, spoofed addresses DoS, SYN attacks etc are a few examples of DoS or DDos (Distributed Denial of Service) attacks. Fortunately the Cisco 7600 router has many robust features and mechanisms to protect itself from such attacks.

In the company that I work (Service Provider) we have already implemented several security protection features on 7600 which are really effective against DoS attacks. A summary of the DoS protection mechanisms on 7600 follows below:

• Security Access Control Lists (ACL): Applied on interfaces to block traffic at Layer3/4 layers.
• QoS Rate Limiting: Using class-maps and policy-maps you can apply rate limiting to specific type of traffic (e.g ICMP)
• uRPF (unicast Reverse Path Forwarding): protects against spoofing attacks. sell cisco routers
• Traffic Storm Control: Protects against broadcast storm attacks.
• TCP Intercept: Protects against SYN attacks.
• Hardware-Based Rate Limiters: Work on PFC3 engines. These rate limiters protect the MSFC routing engine from various packets that can overload its CPU (configured with the mls rate-limit command)
• Control Plane Policing (CoPP): Again used for protection of the MSFC routing engine by applying rate limiting to packets that flow from the data plane to the control plane.

Of course in addition to the above you must not forget other important security mechanisms such as strong password policy, proper Authentication and Accounting, refurbished cisco router logging, SNMP security, Routing Protocols security (MD5 authentication in OSPF, BGP etc) etc. All of these technical issues must be based on a thorough and carefully written security policy.

Router? Switch? Be Clear the Difference Between Router and Switch.

When someone talk about wholesale Cisco router and switch with me, I’m very confused about this. Router Switch? What are they? What are they used for? Oh, My Lady Gaga, complicated.
However, after I have found some details of switch router, it seems a little interesting. Because both router and switch are tightly related to network, to internet. If you have PCs, if you need to email to somebody, or if you want to chat with friends, they are necessarily contained. Haha, eager to get more information of router and switch. I search many details and “the difference between routers cisco and switch” through Google. Now, I’d like share some key info about router and switch.

 
What’s a router-switch? A router is a more sophisticated network device than either a switch or a hub. It is a device that forwards data packets across computer networks, and perform the data "traffic directing" functions on the Internet. On the Internet or on a large corporate network, for example, routers serve as intermediate destinations for network traffic. These routers receive TCP/IP packets, look inside each packet to identify the source and target IP addresses, then forward these packets as needed to ensure the data reaches its final destination. Routers for home networks (often called broadband routers) also can join multiple networks. These routers are designed specifically to join the home (LAN) to the Internet (WAN) for the purpose of Internet connection sharing. In contrast, neither hubs nor switches are capable of joining multiple networks or sharing an Internet connection.
And switch? A network switch or switching hub is a computer networking device that connects network segments. The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. By paying attention to the traffic that comes across it, it can "learn" where particular addresses are. For example, if it sees traffic from machine A coming in on port 2, it now knows that machine A is connected to that port and that traffic to machine A needs to only be sent to that port and not any of the others.
The two pieces of equipment (router and switch) look so similar and perform some similar functions, but each has its own distinct function to perform on a network. To be simple, switches create a network. Routers connect networks. A router links computers to the Internet, so users can share the connection. A router acts as a dispatcher, choosing the best path for information to travel so it's received quickly.
