I. CausesA broadcast storm means that too many broadcast packets consume a large amount of network bandwidth and normal data packets cannot be transmitted over the network. Generally, a broadcast packet causes multiple responses, each response results in multiple responses. Just like a snowball, all the bandwidth of the network is exhausted. This phenomenon is usually caused by network loops, faulty NICs, viruses, etc.Ii. Prevention (take CISCO catalyst

When the center end of the uplink uses a layer-3 Switch for access, the downlink branch node does not need any grade router, only need to be equipped with a hub or switch and G.703-ETH bridge converter, about 10 thousand yuan.

In a managed C ++ project, we can use the "Using namespace" expression to include managed types. just like using "# include" incorrectly will cause some compile error, declaring "Using namespace" globally will cause some problems too. we encountered "ambiguous symbol" error when integrating ASM 4100. to resolve the issue, we can make the "using namespace" impact locally.
For example. The following code may have "ambiguous symbols" error:

At present, with the pace of network product updates accelerating, a considerable number of enterprises and institutions have eliminated and redundant network devices. It would be a pity to discard or discard them. At this time, it is a good idea for network administrators to use them to build a small online lab platform. In addition, there are many training courses, and we also need to build an online lab platform for students of the Learning Network to practice. The following steps allow you t
