The command storm-control broadcast level 75 65 is configured under the switch port connected to the corporate mail server. In which three ways does this
command impact the traffic? (Choose three.)
A.
SNMP traps are sent by default when broadcast traffic reaches 65% of the lower-level threshold.
B.
The switchport is disabled when unicast traffic reaches 75% of the total interface bandwidth.
C.
The switch resumes forwarding broadcasts when they are below 65% of bandwidth.
D.
Only broadcast traffic is limited by this particular storm control configuration.
E.
Multicast traffic is dropped at 65% and broadcast traffic is dropped at 75% of the total interface bandwidth.
F.
The switch drops broadcasts when they reach 75% of bandwidth.
Explanation:
storm-control {broadcast | multicast | unicast} level {level [level-low] | pps pps [pps-low]} Configure broadcast, multicast, or unicast storm control. By default, storm
control is disabled.
The keywords have these meanings:
For level, specify the rising threshold level for broadcast, multicast, or unicast traffic as a percentage (up to two decimal places) of the bandwidth. The port blocks
traffic when the rising
threshold is reached. The range is 0.00 to 100.00.
·(Optional) For level-low, specify the falling threshold level as a percentage (up to two decimal places) of the bandwidth. This value must be less than or equal to the
rising suppression value. The port forwards traffic when traffic drops below this level. If you do not configure a falling suppression level, it is set to the rising
suppression level. The range is 0.00 to 100.00.
In this case, the broadcast keyword was used so only broadcast traffic is limited.
