Reauthentication Period. Specifies the number of seconds in which the selected port is reauthenticated (Range: 300-4294967295). The field default is 3600 seconds.

Quiet Period. Specifies the number of seconds that the switch remains in the quiet state following a failed authentication exchange (Range: 0-65535).

Resending EAP. Specifies the number of seconds that the switch waits for a response to an EAP - request/ identity frame, from the supplicant (client), before resending the request.

Max EAP Requests. The total amount of EAP requests sent. If a response is not received after the defined period, the authentication process is restarted. The field default is 2 retries.

Security Tab - Port Security

Network security can be increased by limiting access on a specific port only to users with specific MAC addresses. MAC addresses can be dynamically learned or statically configured. Locked port security monitors both received and learned packets that are received on specific ports. Access to the locked port is limited to users with specific MAC addresses. These addresses are either manually defined on the port, or learned on that port up to the point when it is locked. When a packet is received on a locked port, and the packet source MAC address is not tied to that port (either it was learned on a different port, or it is unknown to the system), the protection mechanism is invoked, and can provide various options. Unauthorized packets arriving at a locked port are either:

•Forwarded

•Discarded with no trap

•Discarded with a trap

•Cause the port to be shut down.

Locked port security also enables storing a list of MAC addresses in the configuration file. The MAC address list can be restored after the device has been reset.

Disabled ports are activated from the Port Security page.
