Chapter 3 General Management of the Switch 3-141
3.5.1.3 MIB Variables Associated With Port Mirroring
3.5.2 Showing Port Statistics
You can display standard statistics on network traffic from the Interfaces Group and
Ethernet-like MIBs, as well as a detailed breakdown of traffic based on the RMON
MIB. Interfaces and Ethernet-like statistics display errors on the traffic passing
through each port. This information can be used to identify potential problems with
the switch (such as a faulty port or unusually heavy loading). RMON statistics
provide access to a broad range of statistics, including a total count of different
frame types and sizes passing through each port. All values displayed have been
accumulated since the last system reboot, and are shown as counts per second.
Statistics are refreshed every 20 seconds by default.
