04:23:21: %PORT_SECURITY-2-PSECURE_VIOLATION: Security violation occurred,cisco 300-620 book, caused by MAC address 0013.1986.0a20 on port Gi0/2. 120. The second route is 80.0.0.0/8. This route is learned via internal EIGRP Device ID Local Intrfce Holdtme Capability Platform Port ID IP Phone Fas 0/1 147 H P 7960 Finally, we can determine that no security violations have been detected on the interface or port as the counter still has a value of 0. The last source MAC address will be recorded when traffic hits the interface. Banner messages can be: 4.Test Telnet by Telnetting from your PC to your switch. Address Summarization: 3.On the left router turn LLDP off the interface.

Please bear in mind that both your IOS release and platform (router or switch model) must support LLDP if you want to use it. I only bring this up for those of you using a home lab. LLDP is supported in Packet Tracer but the In order for the ip route 0.0.0.0 0.0.0.0 command to work, IP routing must be enabled on the router. Here is an example of configuring a gateway of last resort using the ip route 0.0.0.0 0.0.0.0 command: You could also apply an access control list to the VTY lines and permit only SSH. We will cover access control lists on Day 15. ACL created and applied to interface: interface GigabitEthernet0/2 switchport Switch(config-if)#switchport access vlan 10 Switch(config-if)#switchport voice vlan 11 MD5 digest : 0x7D 0x5A 0xA6 0x0E 0x9A 0x72 0xA0 0x3A Sticky secure MAC addresses are a mix of static secure MAC addresses and dynamic secure MAC addresses. These addresses can be learned dynamically or configured statically and are stored in the MAC address table, as well as in the switch running configuration. This means that when the switch is powered down or rebooted, it will not need to dynamically discover the MAC addresses again because they are already saved in the configuration file (if you save the running configuration).
