(The installation and simple operation manual of h3cimcnta made by ourselves is absolutely original. Using H3C routers and high-end switches (requiring relevant hardware support), together with h3cimcnta components, you can view the traffic of various applications in the network, the proportion of bandwidth, and the traffic of an IP address in real time. Identify HTTP, POP3, SMTP, syslog, SNMP and other traffic services in the network.)
