This command sets an SNMP trap if traffic exceeds the configured rate
limit. Use the no form to restore the default setting.
Syntax
rate-limit snmp-trap-input [up upper-discard-boundary
down lower-discard-boundary]
no snmp-rate-limit trap-input
• upper-discard-boundary – The packet discard rate (per 10 second
interval) above which the system sends a trap-input notification.
(Range: 0-100000)
• lower-discard-boundary – The packet discard rate (per 10 second
interval) below which the system sends another trap-input
notification. (Range: 0-100000)
Default Setting
Disabled

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, page 28-2),
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 opposite
boundary must first be crossed before another trap-input notification
will be sent. However, note that this method is not applicable if the
upper discard boundary is set to 0.
