cisco 48 port poe switch layer 3

The Cisco layer-3 switch is another core switch developed by Cisco. It aggregates the bandwidth of the backboard of the switch that is stacked together, in this way, the total backplane

A typical LAN is to connect a core switch with a layer-3 Switch to several Branch switches (not necessarily with layer-3 switching ). We assume that the core switch name is com, and the

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 applic

Performance Tests on layer-2 and layer-3 vswitches with 24 ports and all-gigabit vswitches have encountered many problems recently. Experts have said that QoS ensures port congestion, high-priority data is processed first. It makes sense to improve the utilization of 24 fully-gigabit switches with insufficient bandwidt

only supports full duplex of Mb, the maximum rate that the switch and customer can automatically negotiate with each other. You can hard-code the process during vswitch initialization to save time. However, this is not always a good choice, because it may not know how fast the client supports. This adaptive time is not long, so consider whether it is worthwhile to perform hard encoding on each vswitch port

breakthrough. In this case, a new routing technology emerges, this is the third tier switching technology: It is a router because it operates on the third layer of the network protocol and is a route-understanding device that can act as a routing decision; it's a switch because it's very fast, and it's almost the speed of a second-tier exchange. Two-tier switches, three-tier switches and routers which of t

More and more cases require Port Security recently. Port security is mainly used to restrict access to port access by binding a client Mac. The ACL between VLANs is not in the current range. After several days of practical debugging, I learned from the experiences of my predecessors and summarized my debugging experiences as follows: 1. cisco29 series switc

enterprises hope to deploy a high-intelligence, high-availability, and high-reliability storage network (SAN) on the basis of cost control ), or, if you want to extend your SAN infrastructure from an entry-level network to enterprise-level deployment, try to protect your SAN infrastructure investment. Cisco's upcoming CiscoMDS9100 series of multi-layer smart Optical Fiber switches will make customers' wishes a reality.

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 e
