@knaik99 hello

switchport port-security maximum 2

"Maximum number of mac address that this interface can learn"

switchport port-security violation restrict

"restrict – is identical with protect mode, but notifies you when a security violation occurs. Specifically, a SNMP trap is sent, a syslog message is logged and the violation counter increments."

switchport port-security aging time 2

"This provides for a MAC address to be removed from being learned after a configured amount of time"

switchport port-security aging type inactivity

"

There are two different methods of implementing secure MAC address aging, these include:

• Absolute—When using this method, secure MAC addresses are deleted after a specific aging time expires.
• Inactivity—When using this method, secure MAC addresses are deleted only if the secure MAC address is inactive for a specific aging time.

"

switchport port-security

"The switchport security feature offers the ability to configure a switchport so that traffic can be limited to only a specific configured MAC address or list of MAC addresses."
