notification. (Range: 0-100000)

Command Usage
If the upper discard boundary is set to 0, then once the configured rate
limit is exceeded (as specified by the rate-limit command, page28-2),
the system issues a trap message regardless of the discard rate.
Once the system starts discarding packets in excess of a rate set for
input, output, or a VLAN member port, and the upper discard
boundary is exceeded, the system issues a trap-input notification. If the
discard rate then falls beneath
the lower discard boundary, the system
will issue another trap-input notification.
To prevent multiple trap-input messages from being sent when the
discard rate fluctuates just above and below a boundary, the opp osite
boundary must first be crossed before another trap-inp ut notification
will be sent. However, note that this method is not applicable if the
upper discard boundary is set to 0.
