An administrator enables port security on a Cisco switch interface using default settings without specifying a violation mode. What default action will the switch take if an unauthorized device connects to this interface?
- AIt drops traffic from the unauthorized MAC address, increments the security violation counter, and sends a Syslog alert while keeping the interface up.
- It immediately shuts down the interface, places it into an err-disabled state, and turns off the port LED.Cevap
- CIt silently drops packets from the unknown source MAC address without altering the port status or incrementing any counters.
- DIt forwards the frame normally but restricts all subsequent broadcast traffic from passing through the interface.
Cevap
The switch immediately shuts down the interface, places it into an err-disabled state, and turns off the port LED.
When port security is enabled on a Cisco switch interface, the default violation mode is shutdown. When an unauthorized MAC address triggers a violation, the interface is immediately placed in an err-disabled state, disabling all traffic through the port until manually re-enabled or automatically recovered.
