STP determines each switch port (specified port: DP; root port: RP; Blocked port: AP)Judgment steps:1. Election of the root switch:Judging object: Select one of all switches running the STP protocol;Judging by: The switch selects

three-layer switch port, meaning that the limit is three layer switch port uplink and downlink traffic control, similarly, if the three-layer switch port is not connected to the PC, but a two-layer

allows packets sent by default VLAN without tags. 1.4 Fabric port Mode The Fabric port is the port between units in IRF. It is only used for interconnection between units and cannot connect users. 2 Application of Hybrid port Mode By introducing the various link port modes

, flexible reception and delivery.2. Further analysis:The difference between a router and a switch is that a switch can only work in an environment that is under the same network segment, but it simply expands the network port. While routers are used for communication between subnets of different network segments, it can form a local area network and manage the l

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 switch module adaptive 1/2 Gbps interface: provides high-performance connections and is compatible with existing devices. IS

1Mbps [Switcha-ethernet0/1]line-rate Inbound 16 The "Supplemental note" message rate limit level is 1~127. If the rate limit level is in the 1~28 range, the rate limit granularity is 64Kbps, in which case, when the level is set to N, the rate limit on the port is n*64k, and if the rate limit level is in the 29~127 range, the rate limit granularity is 1Mbps, in which case When the level is set to N, the r

Before configuring the optical port switch in an Internet cafe, you must first have a rough understanding of the hardware and environment problems of the Internet cafe system, having a good data center environment is good for the overall operation of the optical port switch. "The sustainable development of the Internet

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

the second port, and the experimental phenomenon was identical to the first one. Three, MAC, IP port binding (via AM command) The above two examples, are only the MAC address restrictions, no binding on IP, in practice, many cases will be binding on IP addresses, to avoid the phenomenon of IP conflict. dcs-3950-26c (config) #am enable--turn on the Switch AM f

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

-Gigabit Switch with excellent performance does not have HOL. The test time is 15 seconds. Deep test on address learning rate and address table The address table thoroughly tests the number of MAC address tables for 24 full gigabit switches. The address learning rate checks the speed at which 24 full Gigabit Switches learn MAC addresses. We have used 24 ports A, B, and C of all gigabit switches. Ports A and B are used for sending learning frames and t

company's Lan, what kind of switch should you purchase? According to the current market, the switches required by ordinary small enterprises are not very expensive in terms of price, but they must also take into account the needs of various aspects, for example, if you purchase two or five vrouters that can meet the requirements of eight Connected Networks, two of them must be used as Internet access ports.) in terms of price, it is more expensive th
