the distribution layer or core layer that aggregates hundreds of Mbit/s/Gigabit Ethernet traffic, the IDS working on layer-3 software cannot process massive data. Therefore, it is impractical to monitor all traffic without any choice. How can we find a targeted, effective, and economically scalable solution? With the security features and Netflow integrated by the Catalyst Switch, you can do it! Suspicious Traffic is detected. Using the network traff

restored to normal. and for a long time, the author found that the CPU occupancy rate of the system has been about 15%, which means that the switch platform software upgrade to the latest version, it can really make the switch to maintain vitality. Therefore, when the local area network switch working state has been unstable, we should promptly check the corresponding platform software version high and low, once the switch system version is found to be lower, it must be upgraded in time, this

check the version of the corresponding platform software in time. Once the switch system version is found to be low, we must upgrade it in time, this can solve many hidden failures caused by the switch's own performance. Collect suspicious traffic. Once the suspicious traffic is detected, We need to capture these packets to determine whether the abnormal traffic has undergone a new worm attack. As described above, Netflow does not perform in-depth an

Therefore, when the LAN switch remains unstable, we should check the version of the corresponding platform software in time.

However, both Ipfix and

Microsoft Word users are said to have used only 10% of the software's functionality, as well as those who manage the corporate LAN switches and routers. This situation causes the enterprise to pay the unnecessary purchase and the human cost. An informal survey by some major switch and router vendors shows that users only use less than half of their system's capabilities. Some of the neglected functions focus on the specific functions of network management and security, these vendors say. Broca
