Rmon Configuration; Prerequisites; Configuring Rmon - H3C S7500 Series Operation Manual

Operation Manual – SNMP and RMON
H3C S7500 Series Ethernet Switches
Sampling the alarm variables referenced in the defined extended alarm
expressions once in each specified period
Performing operations on sampled values according to the defined operation
formulas
Comparing the operation result with the set threshold and triggering
corresponding events if the operation result exceeds the threshold.
IV. History group
After a history group is configured, the Ethernet switch collects network statistics
information periodically and stores the statistics information temporarily for later
retrieval. A history group can provide the history data of the statistics on network
segment traffic, error packets, broadcast packets, and bandwidth utilization.
With the history data management function, you can configure network devices, such
as collecting history data, collecting the data of a specific port periodically and saving
them.
V. Statistics group
A statistics group contains the statistics of each monitored port on a network device. An
entry in a statistics group is an accumulated value counting from the time when the
statistics group is created.
The statistics include the number of the following items: collisions, cyclic redundancy
check (CRC) error packets, undersized (or oversized) packets, broadcast packets,
multicast packets, and received bytes and packets.
With the RMON statistics management function, you can monitor the usage of a port
and make statistics on the errors occurring when the ports are being used.
