SHOWING PORT OR

TRUNK STATISTICS

Use the Interface > Port/Trunk > Statistics or Chart page to 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 60 seconds by default.

OTE

RMON groups 2, 3 and 9 can only be accessed using SNMP

management software.
