SuperStack 3 Switch 4400 and other Gigabit Ethernet Switching Products, 3Com provides users with a complete set of advanced enterprise-level LAN Solutions. Cisco Catalyst 3550 features The Cisco Catalyst 3550 smart Ethernet switch is a stackable multi-layer switch product that improves network health through high avai

The naming rules for Cisco switches are more complex than the naming rules for routing,Look at these:ws-c2960-24tc-l, WS-C2950G-24-EI-DC, Ws-c2960-24tt-l, Ws-c3750g-24ts-e, Ws-c3750g-24t-s, We didn't find them on the switch, we just saw the Catalyst 2950 series and wrote it all: The Cisco Catalyst 2950 Series, which means the Cisco switch 2950 series, Catalyst Th

This article mainly introduces how to quickly configure the Cisco Router Network Assistant and provides specific operation steps. I believe this article will benefit you a lot after reading it. Cisco provides Cisco Network Assistant CNA, a free tool for small and medium-sized enterprise SMBs, to help you configure Cisco devices. Of course, you may think that tools that direct to small and medium enterprises are not necessarily applicable to you, but remember that in Cisco terminology, "Small and

Port Analyzer switch Port parser) feature, or the early "port mirroring", "Monitoring port" feature. The listening object can be one or more switch ports, or the entire VLAN. If the port to listen on ("Source port") or VLAN and the port of the Connection monitoring station ("target Port") is on the same switch, we only need to configure span; If you are not on the same switch, you need to configure Rspan (Remote SPAN). Different switches have different restrictions on span, such as the source a

Port speed limit must start QoS on the switch Switch (config) #mls QoS//Start QoS on the switch Here are the implementation steps. First, create an ACL Since this is a three-layer switch, although the port speed limit, but also to consider the network address through the port, in this case, we choose to the CISCO3550 switch 22nd port speed limit, the port belongs to Vlan66,ip address segment 10.66/ 16, so first create an ACL, as follows: 3550#conf T E

This article only targets some models that contain AMD dual-graphics cards and has tested DELL Vostro 3550/DELL flexibility 14R (AMD 6630 and Intel HD 3000 ). The entire installation process requires the use of the command line, but it is still very simple for beginners, you just need to paste the command into the command line, remember to press 1. Uninstall and delete the original driver Ii. Install the latest AMD

As the core network switch of our company, the CISCO3550 has been running stably for many years, and its functions can also meet our needs. However, its port speed limit function is not as easy to implement as some other switches, fortunately, the implementation method has been found recently. After the configuration is complete, it is verified with the iperf software. The result shows that this method is effective. The specific implementation steps are as follows. 1. Create an ACL Because this
