port-security aging time - what is it good for?

[Jacob Berger]

i enabled smartport desktop macro on a port on a 2960 switch.

in the cli it added

switchport port-security aging time 2

switchport port-security aging type inactivity

what do these commands do?

i read about aging and it seems that after 2 minutes of inactivity the connected devices MAC adress would be removed from table.

does that mean  that  after 2 minutes i can connect a different device and the second device will now be the only device allowed?

what kind of security is that?

thanks

Hi!
Flokky123, let me to do an annotation; the switch Cisco 2960S does not support port security aging of sticky secure addresses. Page 411 of Configuring Guide of that device.

does "switchport port-security aging time" affect the maximum of mac address that we specified ? because from what i understand swithcport-security aging time is gonna delete the mac address that it learnt after the specified time.

Please help me to answer this question.

What is the effect of PortFast on the MAC aging process?
 A. It prevents fast aging of MAC addresses when IEEE 802.1 D is in use
 B. It ignores the MAC aging timer when IEEE 802.1 D is in use
 C. It ignores the MAC aging timer when RSTP is in use
 D. It prevents fast aging of MAC addresses when RSTP is in use
