As part of traffic control, you can configure various network security measures:

Storm control. Protect the network by specifying which packet type is allowed on a port 
and at what rate the packets can be transmitted from the port. For more information, see 

166.

Port security. Protect the network by locking a port or LAG and specifying that the port 
can forward only packets from particular source MAC addresses. For more information, 
see 

169.

Protected ports. Protect the network by configuring a port as protected, preventing the 
port from forwarding traffic to other protected ports on the smart switch. For more 
information, see 

175.

A single port that transmits an excessive number of broadcast messages simultaneously 

across the network causes a condition that is referred to as a broadcast storm. Forwarded 
message responses can overload network resources, cause the network to time out, or do 
both.

Operating Control Mode

The actual control mode or actual port authorization state in which the port 
operates, which can differ from the configured control mode:

•

Auto. The port automatically detects the control mode through 

authentication exchanges between the supplicant, authenticator, and 
authentication server.

•

ForceAuthorized. The port functions in the authorized state. The port 
sends and receives normal traffic without client port-based 
authentication.

•

ForceUnauthorized. The port functions in the unauthorized state. The 
smart switch cannot provide authentication services to a client through 
the port.

Reauthentication Enabled

Indicates whether reauthentication is enabled on the port:

•

true. Reauthentication is enabled.

•

false. Reauthentication is disabled.

Port Status

The authorization status of the port, which depends on the configured control 
mode:

•

Authorized. The port functions in the authorized state. The port sends 

and receives normal traffic without client port-based authentication.

•

Unauthorized. The port functions in the unauthorized state. The smart 
switch cannot provide authentication services to a client through the 
port.
