Usage Guidelines

Usage Scenario

To view traps in the trap buffer, run the display trapbuffer command.

Precautions

If there are a large number of traps on the device, running the display trapbuffer command to display specified trap amount is recommended. Otherwise, the following problems may occur due to excessive traps:

The displayed information is repeatedly refreshed, causing desired information unable to be located.
The system does not respond because of long-time information traversing and searching.
