cisco 48 port poe switch layer 2

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

1) layer-2 Exchange Technology The layer-2 switching technology is relatively mature. The layer-2 switch is a data link layer device that ca

The implementation of the multi-port Cisco switch module is a common problem. How to configure the Cisco switch module, any problems related to ports will be fully resolved in this article. Cisco

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 of the

The port rate between switches and switches, between switches and routers, does not meet the actual rate and requires tying more than two ports together to load balance and prevent single points of failure.1.

Branch switches.The Cisco switch can support any media as a trunk line. To achieve relay, you can use its unique isl tag. Isl (inter-switch link) is a protocol for transmitting vlan information and vlan data streams between switches, between switches and routers, and between switches and servers, by configuring isl encapsulation on the

In the middle of a Cisco switching network, how do I find out which port of the switch is connected to the IP address of a machine? The most convenient and quick way is to use the User tracking function of the CiscoWorks 2000 LMS network management software. The graphical interface is clear at a glance. If you do not have this software, you can use the following

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

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.

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

[Cisco] DHCP relay, layer-3 Switch VLAN Routing PracticeThe experiment topology uses the GNS3 0.8.6 simulator to build a DHCP server using Red Hat 6.5. The experiment requires configuring a layer-3 Switch VLAN routing so that VLAN10 and VLAN20 members can access each other.
