distances are sufficient for small networks in the same building! Using the uplink switch fibre port cascade now, more and more switches (except Cisco switches) provide a uplink port, making the connection between the core switches easier. The uplink port is a port that is specifically used to connect to other switches and can be connected to any port other tha

As a good solution to the Internet Access Service, ADSL technology has not been able to be used in the Special Line access service because of the limitation of the traditional Adsldslam in the technical aspect in its early development. The application of the first and second generation Adsldslam limits the application of ADSL technology greatly. Therefore, the third generation of solutions emerged. ——— Editor The first generation of pure ATM structure Adsldslam from downlink line to

communication, paging transmitter frequency interference, broadband repeater, CDMA downlink on the uplink of the interference, TV frequency multiplier on the uplink interference, PHS to GSM interference, electromagnetic interference and so on. There are a wide range of interference in the network, and it is difficult to analyze and locate. Classification of disturbances According to the frequency divisio

QQ transmission file too slow solution Method 1: Change the network If uplink bandwidth is subject to ADSL networks, the best solution is to replace the network with faster uplink bandwidth. Now the whole country in the popularization of fiber to households, if the use of optical fiber, theoretically can reach 20m, the highest to 100m, and upload and download is symmetrical. Method 2: Adjustin

Note: Each interface supports only one policy, and one policy can be used for multiple interfaces. Therefore, the download rate limit for the network segment under the port should be defined in the same policy 1. Start QoS on the switch Switch (config) #mls QoS//Start QoS on the switch 2. Define Access Control List Switch (config) #access-list permit 59.215.45.0 0.0.0.127 Control the upload traffic of the 59.215.45.0 network segment under this port Switch (config) #access-list permit 59.21

. Therefore, the use of flexible small-box ADSL access equipment to become the best choice.Harbor Network for the current large capacity Adsldslam construction mode is not suitable for the edge market, there is a high initial investment, occupy more room area, deployment is not flexible, low rate of the status quo, launched the HAMMER3300IP uplink box-type Adsldslam equipment. It can be cascaded in 4 units, support the single point of expansion to en

Label:10.4 downlink L1/L2 Control signalingThe transmission of the uplink and downlink channels requires a specific "downstream control signaling" to provide support. The downlink control signaling is often referred to as the "downlink l1/l2 Control Signaling", which means that the control signaling is partly from the physical layer (L1) and partly from the MAC layer (L2). The following downlink control signaling details include:1. downlink dispatch a

The "x" in xDSL represents various digital user loop technologies, including HDSL, SDSL, ADSL, RADSL, and VDSL. The following describes the DSL technologies. 1. HDSL high-speed digital user line) HDSL is a symmetric DSL technology with the same uplink and downlink speeds. HDSL use

Vswitch Optical Fiber ports are divided into many types, and their functions are quite different. Here we will mainly introduce some basic knowledge about common optical fiber ports of vswitches. Cascade uses both common ports and special MDI-II ports. A straight-through cable should be used when the two ports that are cascaded are normal ports (MDI-X) ports and MDI-II ports, respectively. Cross-cable should be used when both ports of mutual cascade are common ports, that is, MDI-X) or both are

distance is enough for a small network in the same building! Uplink ports are now available, except for more and more Cisco switches. This simplifies the connection between core switches. Uplink port is a dedicated port used to connect to other vswitches. You can use a straight-through jumper to connect the port to any port other than the Uplink port of another

Vswitch Optical Fiber port cascade connection mode and basic type when the two ports of mutual cascade are common port (that is, MDI-X) port and MDI-II port, should use a straight-through cable. Cross-cable should be used when both ports of mutual cascade are common ports (that is, MDI-X) or both are MDI-II ports. Whether it is 10Base-T Ethernet, 100Base-TX fast Ethernet, or 1000Base-T Gigabit Ethernet, the length of the cable used by the cascade switch can reach 100 meters, which is exactly the

In the process of using the router, the Internet terminal download speed is normal, upload speed is very slow: Please refer to the following methods for troubleshooting: Upload speed depends mainly on the uplink bandwidth, and the vast majority

switch is the core of a physical network. Multiple switches can be connected together to form a larger network. The vSphere Standard switch operates in much the same way as a physical Ethernet switch. It detects a virtual machine that is logically connected to its virtual port and uses that information to forward traffic to the correct virtual machine. The virtual network can be connected using a physical Ethernet adapter (also known as an uplink ad
