You have been asked by your superior to configure all Cisco network switches to allow only acceptable MAC addresses through switch access ports. How is this accomplished?
Use the mac-limit command to prevent more than one MAC from being accepted.
Use the switchport port-security command to enable MAC filtering.
Use the secure port mac-address command to limit the port to learned addresses only.
Use the allowed-mac command to filter by MAC address.
Answer:
Use the switchport port-security command to enable MAC filtering.
Explanation:
Use the switchport port-security command to enable port-security. By configuring port-security only one MAC address is allowed. Once the switch sees another MAC address on the interface it will be in violation and something will happen. And Use the switchport port-security mac-address command to define the MAC address that you want to allow.
Please give thumbsup, if you like it. Thanks.
