Layer-3 Switch for Cisco switches Although single-arm routing solves the communication problem between different VLANs, it also has its fatal defects: -The single arm itself is the Backbone link of the network, which is easy to form a network bottleneck. -The sub-interface relies on physical interfaces, and the application is not flexible -You need to view the r

Cisco smart switch: Catalyst 4500 intermediate modular Chassis Catalyst 4500 with Supervisor Engine V. It is suitable for deployment of backbone networks, distribution layers, and service providers of small enterprises. Provides management

Precautions and categories for purchasing cisco Gigabit Switches. We will introduce the precautions for cisco Gigabit Switches. Many people may not know how to classify cisco Gigabit Switches, after reading this article, you must

There are still prospects for the security deployment and upgrade of cisco switches. There may be no specific cisco switch security mode for the cisco switch Security description, so it may not help you, cisco switch security has become a new highlight in the switch market.

#show Interfaces | In (is Up|5 min) to see which interface packet volume is huge, if this is a large number of port is not a cascade port, then congratulations, basically found the source.4. If the distribution layer switch is more, repeat the above command repeatedly to find out the source location.5. At this time, you can:1, shutdown this interface2, the implementation of storm control3. Spanning-tree Hos

Overview Fixed-installation line-rate fast Ethernet desktop switch Cisco Catalyst 2950 series for LAN) provides excellent performance and functionality. These independent, 10/100 adaptive switches provide enhanced service quality QoS) and multicast management features, all of which are provided by the easy-to-use, Web-based Cisco Cluster Management Suite CMS) and

distribution layer and the access layer, we need to adopt a comprehensive enterprise security policy to protect the entire network and the connected system. In addition, even when a worm occurs, we need to take measures to minimize its impact and protect our network infrastructure to ensure stable network operation. This article describes a unique solution on a

In the network industry, Cisco System Inc. is unknown. With its IOS (Internet Operating System), Cisco is an absolute leader in the multi-protocol router market. Currently, nearly 80% of routers on the Internet come from Cisco. In fact, Cisco also has a full range of network devices, including hubs,

Overview of LAN Switches The LAN switch has developed into a more expansive space from the traditional hub-and-LAN. For example, Cisco's Catalyst 5000 series LAN switch includes an integrated switched hardware architecture that supports switched 10-mbps Ethernet and 100-mbps Fast Ethernet, with Fast Ethernet, FDDI, switched token Ring, and layer 3rd switching capabilities. This class of

Many SME internal network structures are simple, with only one switch connecting all employees and servers together and then accessing the Internet through fiber optics. Of course, in order to ensure the security of some hosts and split the internal broadcast packet to improve the network transmission speed, take such as partition VLAN, the allocation of different subnets to achieve. By partitioning VLANs, clients on different ports on the same switch cannot access each other, effectively isolat
