Cisco is now the world's largest manufacturer of switching routes! Many of our businesses, large and small, can use the network, and it is possible to switch routes to Cisco! When we install network equipment, we may ask the network engineer to help us install it! Access to the router has a lot of passwords! What if we forget these passwords? We may have to make changes to the routing entries when our compa

"Introduction" is a Cisco with Stackwise Plus? Catalyst? The 3750-E series switches are an enterprise-class, stand-alone, stackable wiring switch family that supports the deployment of secure converged applications and maximizes investment protection based on the development of network and application requirements. By combining A/V and power over Ethernet (PoE) configuration with a Gigabit Ethernet uplink, the Cis
Now that Cisco Nat is flexible, Can Linux implement it? The answer is yes! Linux netfilter is super flexible, and Linux Nat is not flexible because the iptables program is not flexible. xtables-Addons rawnat has taken an important step towards static Nat, iptables restricts the development of static Nat in Linux! So I put aside iptables, first implemented the kernel module based on Netfilter, and then used procfs as the user interface to see how to im

12000 the Cisco router series is very suitable for small and medium-sized enterprises. Here we mainly analyze the performance characteristics of the Cisco router series. In today's information age, enterprise mail has become an essential tool for business communication and communication. With the new routing technology, enterprise mail also has more and more innovative features.
However, compared with diver
After the popularization of broadband, Cisco wireless router settings are frequently faced. So today, I am going to introduce you to the configuration skills of Cisco Wireless routers. I hope this article will teach you more things and bring convenience to your life.
After broadband popularization, many friends who have multiple computers or laptops want to install wireless hotspots at home. Because they se
Cisco configuration instance _ Cisco dual-Egress NAT configuration objective: to simulate the routing function based on the original address policy when a dual-Egress link is available, and access to the external network from different original addresses is realized, in most cases, the vro uses NAT to translate the Intranet address on the external port, so this experiment also uses dual NAT to translate the
Introduction after you log in to the CISCO switch, we will need to use some common operations, such as querying, restarting, and so on, where some of the commonly used operations are grouped together. Query HelpIn different modes, we can enter the question mark directly (? You can query all the commands that you can use in the current mode. When entering a command, if you do not remember the full name of the command, enter the first few characters

Tags: process proc ima RAC Technology share static term ADOBy configuring static routes, you can achieve an increase in routing entries for routers in a relatively simple network.However, if there are more than 20 routers in a network, it is difficult to configure static routes to accommodate the complexity of routing entries and changes in the network. At this point we can use the RIP protocol to configure simple dynamic routing, thus reducing the workload.Configuration ideas1 Configure the IP
