H3C S9500 Series Routing Switches
Note:
Before adding extended alarm entry, you need to define the referenced event in the
extended alarm entry by using the rmon event command.
You can define up to 50 prialarm entries.
Perform the following configuration in system view.
Table 6-4 Add/delete an entry to/from the extended RMON alarm table
Add an entry to the extended
RMON alarm table
Delete an entry from the
extended RMON alarm table
After you define the extended alarm entry, the system processes the entry in the
following way:
1) Sampling the defined prialarm-formula according to the time interval
sampling-time that you have set
2) Performing the operation to the sampled value according to the defined formula
prialarm-formula
3) Comparing the result with the configured threshold and handling them in the way
described in the following table
Table 6-5 Handling the extended alarm entry
The result is greater than the configured
upper limit threshold-value1
The result is less than the configured lower
limit threshold-value2

6.2.4 Adding/Deleting an Entry to/from the History Control Table

The history data management helps you set the history data collection, periodical data
collection and storage of the specified ports. The sampling information includes the
utilization ratio, error counts and total number of packets.
