Traffic Flow Analyzer
OpenManage Network Manager’s Traffic Flow Analyzer listens on UDP ports for sFlow, datagrams.
A flow is a unidirectional stream of packets between two network nodes. The following key
parameters appear in flows:
• Source IP address
• Destination IP address
• Source port number
• Destination port number
• Layer 3 protocol type
• ToS byte (Type of Service)
• Input logical interface
• Destination IP address
• Source port number
• Destination port number
• Layer 3 protocol type
• ToS byte (Type of Service)
• Input logical interface
Using that data, Traffic Flow Analyzer can help you visualize network traffic, troubleshoot and
anticipate bottlenecks.
NOTE:
Typical packages come with a default limit to the number of monitored devices. Upgrade your license if
you want to exceed the package limit.
Supported versions include sFlow v5.
Parse errors can appear in the application server log for some flow data.
