You have altered the factory-default storm control configuration so that interfaces on which the storm control level is exceeded are temporarily shut down for five minutes.
Which two methods can you use to monitor that the auto recovery feature is working? (Choose two.)

A.
Issue the monitor traffic violations command.

B.
Issue the monitor start messages command.

C.
Issue the show storm-control violations command.

D.
Issue the show ethernet-switching interfaces command.

Explanation:
Disabling or Enabling Storm Control (CLI Procedure)

The factory default configuration enables storm control on all EX Series switch interfaces, with the storm control level set to 80 percent of the combined applicable traffic streams, as follows:

On EX2200, EX3200, and EX4200 switchesThe factory default configuration enables storm control on all interfaces at 80 percent of the combined broadcast and unknown unicast streams. It does not enable storm control for multicast traffic by default.
On EX4500 and EX8200 switchesThe factory default configuration enables storm control on all interfaces at 80 percent of the combined broadcast, multicast, and unknown unicast streams.

You can disable storm control for all the applicable types of traffic on all interfaces or on a specified interface, as follows:

On all switchesYou can selectively disable storm control for broadcast streams, multicast streams, or for unknown unicast streams.
On EX8200 switchesYou can also selectively disable storm control on registered multicast traffic, on unregistered multicast traffic, or on both types of multicast traffic.
You can enable storm control for multicast traffic (both registered and unregistered) on all interfaces or on a specific interface. This applies to all switches.

Disabling Storm Control on Broadcast Traffic
To disable storm control on broadcast traffic:
For all interfaces:
[edit ethernet-switching-options]
user@switch# set storm-control interface all no-broadcast
For an individual interface:
[edit ethernet-switching-options]
user@switch# set storm-control interface interface-name no-broadcast

Disabling Storm Control on All Multicast Traffic
To disable storm control on all multicast traffic:
For all interfaces:
[edit ethernet-switching-options]
user@switch# set storm-control interface all no-multicast
For an individual interface:
[edit ethernet-switching-options]
user@switch# set storm-control interface interface-name no-multicast

Disabling Storm Control on Registered Multicast Traffic (EX8200 Switches Only)
To disable storm control only on registered multicast traffic (on EX8200 switches only):
For all interfaces:
[edit ethernet-switching-options]
user@switch# set storm-control interface all no-registered-multicast
For an individual interface:
[edit ethernet-switching-options]
user@switch# set storm-control interface interface-name no-registered-multicast

Disabling Storm Control on Unregistered Multicast Traffic (EX8200 Switches Only)
To disable storm control only on unregistered multicast traffic (on EX8200 switches only):
For all interfaces:
[edit ethernet-switching-options]
user@switch# set storm-control interface all no-unregistered-multicast
For an individual interface:
[edit ethernet-switching-options]
user@switch# set storm-control interface interface-name no-unregistered-multicast

Disabling Storm Control on Unknown Unicast Traffic
To disable storm control on unknown unicast traffic:
For all interfaces:
[edit ethernet-switching-options]
user@switch# set storm-control interface all no-unknown-unicast
For an individual interface:
[edit ethernet-switching-options]
user@switch# set storm-control interface interface-name no-unknown-unicast

Enabling Storm Control on Multicast Traffic
To enable storm control on multicast traffic:

Note: We do not recommend enabling storm control on multicast traffic on aggregated Ethernet interfaces on EX2200, EX3200, and EX4200 switches.

For all interfaces:
[edit ethernet-switching-options]
user@switch# set storm-control interface all multicast
For an individual interface:
[edit ethernet-switching-options]
