Port Security Flashcards
What does port security use to authenticate frames?
The source MAC address.
Port security can only be configured on what kind of ports?
Access ports.
List the four options available when configuring an interface for port security.
Maximum, aging, MAC-address and violation.
What does the “Maximum” option configure?
The total number of secure MAC addresses allowed on a port.
What does the “Aging” option configure?
How long it takes for a secure MAC to age out, and when the aging starts (absolute or inactive).
What does the “MAC-Address” option configure?
The static MAC addresses, or enable sticky addresses.
What are the three violation options and their functions?
Shutdown (default) which err-disables the port, protect which discards offending frames, and restrict which discards offending frames and generates an SNMP trap/log.
What is the default port security interface config?
1 MAC allowed, dynamically learned, shutdown violation.
What are sticky addresses?
Dynamically-learned addresses that are saved to their interface in the running config.
