rate, error, or other parameters exceed the threshold. Then, we use network management or monitoring tools to find out why the threshold has exceeded. In fact, almost all switches provide the SNMP monitoring switch function, even the cheapest switch. The main difference between them is the information provided. Some low-priced vswitches only provide simple SNMP monitoring switch information, which is for the entire vswitch. Those expensive vswitches can also provide detailed information about e

fails, it is transferred to another line. Mode = 0 indicates the server load balancer mode. both NICs work and must be supported by the switch. Mode = 1 indicates the redundancy mode. only one network adapter works. if one problem occurs, another one is enabled. Mode = 6 indicates the server load balancer mode. both NICs work and do not require support from vswitches. Here I am binding four NICs, and the server is dell R720. the default Nic name is em1 -- em4. when the NIC is bound, the config

The suspicious snmp service is reflected in many software. So we will introduce the Cacti software today. Now I will give a brief introduction to some functions and operations of this software. The Cacti Chinese version is a software implemented in php. Its main function is to use the snmp service to obtain data and then use rrdtool to store and update data, when you need to view data, use rrdtool to generate charts and present them to users. 1. test whether the snmp service is normal #snmp

support for SNMP monitoring switch has different MIB libraries (Management Information Library ). Each type of MIB is different. In addition to some private MIB that support your vswitch, the standard MIB library is also very useful for monitoring the switching network. The following are some
