Layer two traffic control is provided by Cisco Catalyst switches with port security.
The security of individual ports can be enabled. A packet with an MAC address matching the one forwarded is secure all other packets are unsecure. The Port Security utility prevents unknown devices from forwarding packets over the network. MAC address 0090 was responsible for the last violation, as you can see the violation mode is shutdown. You can display the details of each port security interface by using the show port-security command.

An interface is provided by the boot loader for accessing files on the flash drive. In cases where operating system files are missing or damaged, the boot loader allows access to the switch.

Where are dynamically learned MAC addresses stored when sticky learning is enabled with the switchport port?Īs of release 8.1, sticky learning maintains dynamically learned MAC addresses in the running configuration in RAM and will not be lost on reboots or interface failures. By setting this limit, the amount of discovery messages in the interface each second can be limited. L2 addresses are learned dynamically and copied to the running configuration to ensure consistency. Using this command, a switch's ports are secured globally. What is the effect of using the Switchport port security?Ī switch can be configured to have port security enabled by entering the switchport port-security configuration command.
All ports with port security enabled run in port violation mode by default.
