control response for rate limiting will be released after the Release Timer
expires, if so configured by the auto-traffic-control auto-control-release
command. Use the no form to restore the default setting.
SYNTAX
auto-traffic-control {broadcast | multicast} alarm-clear-

no auto-traffic-control {broadcast | multicast} alarm-clear-
threshold
broadcast - Specifies automatic storm control for broadcast traffic.
multicast - Specifies automatic storm control for multicast traffic.
threshold - The lower threshold for ingress traffic beneath which a
cleared storm control trap is sent. (Range: 1-255 kilo-packets per
second)
DEFAULT SETTING

COMMAND MODE
Interface Configuration (Ethernet)
COMMAND USAGE
◆ Once the traffic rate falls beneath the lower threshold, a trap message
may be sent if configured by the snmp-server enable port-traps atc
broadcast-alarm-clear command or snmp-server enable port-traps atc
multicast-alarm-clear command.
◆ If rate limiting has been configured as a control response, it will be
discontinued after the traffic rate has fallen beneath the lower
threshold, and the release timer has expired. Note that if a port has
been shut down by a control response, it will not be re-enabled by
automatic traffic control. It can only be manually re-enabled using the
auto-traffic-control control-release command.
