computers. NetFlow: in fact, most Cisco routers support the NetFlow protocol, which can calculate bandwidth utilization. Although its configuration is the most complex, it is still the most powerful and suitable method for networks with large network communication traffic. Cisco devices that support NetFlow can track the bandwidth utilization of the network from

This article describes how to control the BT traffic of a Cisco router through specific operations, and describes the specific operation methods in detail. I hope this article will help you. Network-Based Application Recognition (NBAR) indicates Network Application Recognition. NBAR is a technology that can dynamically search for protocols in Layer 4 to Layer 7.

Network-Based Application Recognition (NBAR) indicates Network Application Recognition. NBAR is a technology that can dynamically search for protocols in Layer 4 to Layer 7. It can not only control static and simple network application protocol TCP/UDP port numbers in general ACLs. For example, the TCP 80 used by well-known WEB applications can also control the protocols that generally cannot achieve dynamic ports in ACLs, such as H.323 and SIP used by VoIP. BitTorrent (BT) is a P2P software tha

There are too many Qos information on the Cisco Router Traffic Control instance, but many of them are not practical. I have talked about a lot of theories. The following are the configurations on the routers of a subsidiary for your reference. In fact, as long as you understand the meaning of NBAR, CBWFQ, and WRED, traffic control can be configured as needed. Www

When a traffic analysis problem occurs, such as excessive traffic pressure, poor IPS analysis, and CPU overload, you can configure SNMP to trigger an alarm. When will the alarm be triggered, you need to configure the threshold value for the traffic notification on Cisco IPS, as shown in Figure 5.3: 650) this. width

Cisco L3 switch Policy Routing for network access and Traffic DistributionI. Description of the solution environment 1.
