Internet Operating System (IOS) is Cisco's private core software package, which is mainly implemented on Cisco routers and switches. Cisco IOS software uses a set of value-added technologies and features to provide Internet intelligence.Cisco IOS includes a group of superb network technologies, mainly composed of internet devices such as a single router, it is us

For Cisco Network Assistant (CNA), it is estimated that Cisco has launched a free tool that can be used to configure Cisco devices such as Catalyst switches, PIX firewalls, IP phones, and wireless access points, CNA support, As long as it is facing small and medium enterprises. CNA provides a number of features and wiz

Premise: With the development of the network, network security has become an important topic at present. More and more companies will choose to use the firewall as the company's egress device. Compared with the router, the firewall not only has the forwarding routing function, it can also filter internal and external traffic to further enhance the security of the company's

Nat[network address translation] In the absence of IP address in the case of a great use, it can not be normal Sisu network of the intranet address into a legitimate external network address on the public network to send and receive data. At the same time address translation function can also be very good to hide and p

Network address port Conversion NAPT is a very familiar way of transformation. NAPT is commonly used in access devices, which can hide small and medium-sized networks behind a legitimate IP address.Unlike dynamic address NAT, NAPT maps An internal connection to a separate IP address in the external network, adding a TCP port number selected by the NAT device to the address.This time, let's get to know napt.

RIP protocols can be configured in a more convenient way, but the limitations of RIP itself indicate that it is not suitable for medium to large networks. In contrast, OSPF is more complex to configure than RIP, but its functionality and performance are better than RIP.Configuration ideas1 Configure the physical interface address of the router Xia Lian switch and the physical interface address of the router to the other router and open the port2 Configure the address of the switch Xia Lian PC an

Through the previous experiment we learned that by configuring VLANs, the terminals under different VLANs could not communicate with each other, but if you wanted to communicate between different VLANs, you would need to configure inter-VLAN routingLayer three switches have the capability of the network layer and can be forwarded via the routing functionNetwork environment1 set the IP address and gateway of the terminal (192.168.1.1 and 192.168.2.1, r

Tags: color-o switch test one-arm routing access via interface implementation representationTo achieve inter-VLAN communication, in addition to configuring the SVI interface on the switch, you can also implement VLAN data forwarding by configuring sub-interfaces under the physical interface of the router.Configuration ideas:1 The access switch configures the corresponding VLAN and sets the access PC port to access mode2 Setting the physical interface of the router to which the switch is connecte

The loop has a great impact on the network. Spanning Tree protocol is a good solution to this problem.The idea of spanning a tree protocol topology is that, regardless of the physical connection between switches, the switch

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
