The port shuts down when the maximum number of secure MAC addresses is exceeded, and an SNMP trap notification is sent. Default Port Security Configuration Feature If you need to study more about switch port security, try to read a book or simply read the below materials. That’s all, you need to learn about to configure switch port security on Cisco switches. Why is PC2 able to ping PC1, but the Rouge Laptop is not? Disconnect Rouge Laptop and reconnect PC2. Display the port security violations for the port Rogue Laptop is connected to. Verify that Rogue Laptop is unable to ping PC1. Disconnect PC2 and connect Rogue Laptop to PC2’s port.

#PORT SECURITY ON CISCO 2950 SWITCH VERIFICATION#

After verification shut down the port connected to Rogue Laptop.

Enable the port and verify that Rogue Laptop can ping PC1 and PC2. Attach Rogue Laptop to any unused switch port and notice that the link lights are red. Verify port security is enabled and the MAC addresses of PC1 and PC2 were added to the running configuration with “ show run” command. Try to test your switch port security configuration with ping command and testing with the rogue laptop on the lab It’s all and enough to configure switch port security on this lab. SW1(config)#interface range fastEthernet 0/3-24, gigabitEthernet 0/1-2 Hint: Use the range keyword to apply this configuration to all the ports simultaneously. SW1(config-if-range)#switchport port-security violation restrictĮ. Set the violation so that the Fast Ethernet ports 0/1 and 0/2 are not disabled when a violation occurs, but packets are dropped from an unknown source.

SW1(config-if-range)#switchport port-security mac-address stickyĭ. Secure the ports so that the MAC address of a device is dynamically learned and added to the running configuration. SW1(config-if-range)#switchport port-security maximum 1Ĭ. Set the maximum so that only one device can access the Fast Ethernet ports 0/1 and 0/2. SW1(config-if-range)#switchport port-securityī. SW1(config-if-range)#switchport mode access SW1(config)#interface range fastEthernet 0/1-2 SW1>enableĮnter configuration commands, one per line. Access the command line for S1 and enable port security on Fast Ethernet ports 0/1 and 0/2. Port security allows you to restrict a port’s ingress traffic by limiting the MAC addresses that are allowed to send traffic to the port.Ī. In this activity, you will configure and verify port security on a switch.

These sections describe how to configure port security using the Packet Tracer – Configuring Switch Port Security Lab.

A secure port and static MAC address configuration are mutually exclusive.

A secure port cannot belong to an EtherCha nnel port-channel interface.

A secure port cannot be a destination port for Switch Port Analyzer (SPAN).
