FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Dell Astute\User Guide\Dell_Astute_Network_Admin_Security.fm To view ports and their authentication definitions: 1 Click Network Administration > Security > Dot1 Authentications > Port Authentication Users. The ports and their authentication definitions are displayed. - User Name - Supplicant names that were authenticated on each port. - Port - Number of port. - Session Time - Amount of time (in seconds) that the supplicant was authenticated and authorized access at the port. - Authentication Method - Method by which the last session was authenticated. The options are: • None-No authentication is applied; it is automatically authorized. • RADIUS-Supplicant was authenticated by a RADIUS server. • MAC Address-Displays the supplicant MAC address. - MAC Address - MAC address of user who attempted to be authenticated. - VLAN - VLAN assigned to the user. - Filter - Filter that was applied to the user by receiving the policy/ACL name from the RADIUS server (Dynamic ACL Assignment). Storm Control Configuration When Broadcast, Multicast, or unknown Unicast frames are received, they are duplicated, and a copy is sent to all possible egress ports. This means that in practice, they are sent to all ports belonging to the relevant VLAN. In this way, one ingress frame is turned into many, creating the potential for a storm. Storm protection provides the ability to limit the number of frames entering the switch, and to define the types of frames that are counted towards this limit. When a threshold (limit) is configured on the device, the port discards traffic when that threshold is reached. The port remains blocked until the traffic rate drops below this threshold. It then resumes normal forwarding. DELL CONFIDENTIAL - PRELIMINARY 8/9/16 - FOR PROOF ONLY Network Administration: Security 255

Storm Control Configuration
When Broadcast, Multicast, or unknown Unicast frames are received, they are
duplicated, and a copy is sent to all possible egress ports. This means that in
practice, they are sent to all ports belonging to the relevant VLAN. In this way,
one ingress frame is turned into many, creating the potential for a storm.
Storm protection provides the ability to limit the number of frames entering
the switch, and to define the types of frames that are counted towards this
limit.
When a threshold (limit) is configured on the device, the port discards traffic
when that threshold is reached. The port remains blocked until the traffic rate
drops below this threshold. It then resumes normal forwarding.
