1 The use of the tunnel interface
The use of the tunnel interface is MA5633 relatively simple, this type of interface is actually a specialinterface of GRE protocol. GRE (Generic Routing Encapsulation) is a kind of layer three tunneling protocol, the most commonly used methods for the use of IP message and GRE message, GRE message is still loading the IP message.

The use of modular router, the user can OSN 3500 according to their own business needs, the routerport density, reliability, multi business application and the throughput of the module and other aspects of flexible configuration, personalized to provide different service. The choice ofdifferent modules, to achieve different functions. More importantly, modular router also can according to future business growth and change, by increasing the module to realize smooth network expansion and upgrade, to minimize the network architecture and the existing equipment adjustment, fully protect the original investment.
Huawei AR1200 series, petite size has two slots, the expansion of business areas have a great advantage

1 Router port scanning.
Scanning router port to router security, Catalyst 2960S Price network management is usually the default port router(80) to change it, so the first step we crack the router password is must find the router wEBport management.
If the router UPnP (universal plug and play, is a general term for a group of protocol) functionis turned on (usually the router by default UPnP is turned on), then the router will open a L900 port.
We use TP Link router as an example, as long as the open http://192.168.1.1:l900/igd.xml router view the http://192.168.1.1:80808080 is the router wEB login port.
If the UPnP is management closed the case, then we can only scan tool to scan. Open the Xscan, enter the IP address 192.168.1.1

(1) the wireless interference detection PDIA we can use to provide access to services of AP to scan, also can through the special equipment is composed of the network, positioning handheld RF equipment, precise positioning network or a small range is generally applicable to small, and large network, the generalneed to deploy special network to monitor.
(2) wireless interference is continually monitor the empty signal,when the empty signal energy exceeds a certain value, then the FFT transform, and further output to the wireless receiver and various recognizer,the former judge whether the wireless signal interference, and further analysis of MAC information, which determine the type of non wireless interference source

Question 1: how to clear the User configuration EAS2 information of the current configuration file ?
Answer 1: use the reset saved-configuration command in the user view, delete the switch current configuration file in the user information.
The contents of the file when the configuration files are erased, space configuration file the same name will be created, and load the HGMP initial configuration file. Save the configuration information, when Switch restarts, loading the HGMP default enableconfiguration.
Reset saved-configuration is generally used in the following circumstances: will a have configured the switch to the new application environment, the original configuration file can not adapt to the new environment needs, need to re configure the... Read More
Huawei ping command is divided into: SL4D VRP platform based on the ping command and the ping command based on Windows platform
A, VRP platform based on ping command
This section describes several VRP platform used in the ping commandparameters.
Ping [-a source-ip-address -c count -s packetsize | | | -t timeout] * host
L -a source-ip-address: the source IP address is set to send ICMP EchoRequest message.
L -c count: ICMP Echo Request sets the number of times to send packet, the default value is 5.
L -s packetsize: ICMP Echo Request is set to send the packet length (not including IP and ICMP headers), in bytes, the default value is 56.
L -t timeout: set Ping message timeout, the default value is 2000ms.

The basic principle of VoIP is: the speech air-ap1262n-e-k9 data codes are compressed by voice compress algorithm, then the voice data according to TCP/IP standards for packaging, through IP network packets sent to the receiving, and then string these voice packets, after decompression treatment, restorethe original speech signal, thus achieve from the Internet to send voiceobjective.
The experimental environment: Cisco 3600 Router, 12.3 IOS.
The configuration of the Cisco Voip:
1: pre configuration
IP address 22.214.171.124 255.255.255.0

The existence of SDN has two standards, huawei EGS4 one is the OpenFlow protocol,standard work is maintained and developed by ONF organization, many manufacturers have introduced switch and Controller support OpenFlow,many large enterprises have begun to try to use the user. The other is the I2RS (Interface to the Routing System) protocol, the standards set by the IETF control layer, communication with the external in the traditional networkrouting equipment and forwarding system based on open new interface toexternal control layer, through feedback events, topology, traffic statisticsand other information to the underground route state wait until all devices,strategy.
