Rmon Configuration - H3C S3100-52P Operation Manual

Operation Manual – SNMP-RMON
H3C S3100-52P Ethernet switch
III. Extended alarm group
With extended alarm entry, you can perform operations on the samples of alarm
variables and then compare the operation results with the thresholds, thus implement
more flexible alarm functions.
With an extended alarm entry defined in an extended alarm group, the network devices
perform the following operations accordingly:
Sampling the alarm variables referenced in the defined extended alarm
expressions periodically
Performing operations on the samples according to the defined expressions
Comparing the operation results with the thresholds and triggering corresponding
events if the operation result exceeds the thresholds.
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 use. 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 to
collect history data, sample and store data of a specific port periodically.
V. Statistics group
Statistics group contains the statistics of each monitored port on a switch. 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, packets with Cyclic
Redundancy Check (CRC) errors, undersize (or oversize) packets, broadcast packets,
multicast packets, and received bytes and packets.
With the RMON statistics management function, you can monitor the use of a port and
make statistics on the errors occurred when the ports are being used.

2.2 RMON Configuration

Before performing RMON configuration, make sure the SNMP agents are correctly
configured. For the information about SNMP agent configuration, refer to section
Configuring Basic SNMP Functions.
