the price varies from place to place, The price should be 3898, which basically fluctuates around here. I've seen 3500 low cars and 4100 high cars that don't give anything away, so it's better to ask more. I'm also paying attention to this car, and I'm going to get one when I can.

several popular models on the Internet, after experiments, the four core low-frequency is indeed a little more powerful than the al core high-frequency. Amd can't compete with Intel Core 2 in high-end,
q6.q7 series below four core Q8200 are all eliminated, and Q8200 is cheaper than better al core. This is the main reason why we are optimistic about it
now some people reflect that some programs do not support multi-core, but the number of support is decreasing, the number of support is increasing, and the number of support can be changed to support
four core computer is the trend of future development, and the future four core computer can play a more important role in system operation and program operation.
As shown in Figure 1, enterprise user department 1 and department 2 are connected to the Internet network through switchA. Users want to know the communication between the two departments and the Internet network, and then charge by department
figure 1netstream networking diagram
configuration ideas
users can deploy the IPv4 original flow statistical information output function in the ge0 / 0 / 1 interface of switchA, count the flow information of the out and in directions of the interface, and send it to the netstream server for subsequent analysis, so as to monitor the communication between the two departments and the Internet network, And provides the basis for the sub department billing
adopt the following configuration ideas:
1. Configure the IP address of switchA interface
2. Configure netstream sampling function
3. Configure the stream aging of netstream
4. Configure the output of original stream statistics of netstream
5. Configure the output message version format
6. Enable the netstream statistics function of the interface
operation steps
1. As shown in Figure 1, configure the interface IP address of switchA
? Configure the interface IP address of switchA

2. Configure netstream sampling function
? Configure the netstream sampling function of ge0 / 0 / 1 interface, The sampling method is fixed message interval sampling, and the message interval is 1200
[switchA] interface Gigabit Ethernet 0 / 0 / 1
[switchA Gigabit Ethernet 0 / 0 / 1] IP netstream sampler fix packets 1200 inbound
3. Configure netstream stream aging
? Configure inactive stream aging time as 100 seconds, And turn on the fin and RST packets of TCP connection to trigger aging
[switchA] IP netstream timeout inactive 100
[switchA] IP netstream TCP flag enable
4. Configure the output of original netstream statistical information
? Configure the output of original netstream statistical information with source address of 10.1.2.1, destination address of 10.1.2.2 and destination port number of 6000
[switchA] IP netstream export source 10.1.2.1
[switchA] IP netstream export host 10.1.2.2 6000
5. Configure the output message version format
? Configure the output message version as V9

[switchA] quit
7. Verify the configuration result
? After the configuration is successful, the netstream server can receive the statistical message sent by the device. The display IP netstream statistics command can be used on the local device to view the netstream statistics
