Usage Guidelines

Usage Scenario

When the NMS obtains interface traffic statistics through the MIB tables iftable and ifxtable, the time for querying interface traffic statistics in real time is long. When the device has a large number of interfaces, the query efficiency of the NMS is low. To resolve this issue, switches can be configured to periodically collect traffic statistics on interfaces. In this case, the NMS can directly obtain traffic statistics collected on interfaces, improving the query efficiency.

Precautions

If the command has been run for multiple times, only the latest configuration takes effect.
When the undo set if-mib sample-interval [ interval-value ] command is run, if the interval is specified, the value must be consistent with the current configuration.
A short interval will cause a high CPU usage.

Example

# Set the interval of collecting traffic statistics on an interface to 100 seconds.
