SW1 conf t Enter configuration commands, one per line. Dynamically locked MAC addresses are aged out if another packet with that address is not seen within the age-out time. The MAC address of this device will be flushed after 2 minutes of inactivity (this is actually relevant only if another switch was connected to the Gi1/0/1 port because a disconnection of the device on the second switch would not be noticed by your Gi1/0/1 port, and hence, there must be some limit after which old dynamic secure MAC addresses are removed - but if there is a device directly connected to the Gi1/0/1, after it is disconnected, the dynamic secure MAC will be flushed immediately). In this post I will give you the commands needed to implement some security features in a Cisco switch in a cheetsheet like manner. Aging Time : 0 mins Aging Type : Absolute SecureStatic Address Aging : Disabled Maximum MAC Addresses : 1 Total MAC Addresses : 1 Configured MAC Addresses : 0 Sticky MAC Addresses : 1 Last Source Address:Vlan : :1 Security Violation Count : 1.

So the earlier you close the holes the better!Īs an example security features like protected ports can effectively harden lateral movement in windows networks (Active Directory domains), also while being so dead simple compared to more advanced methods implemented on top of active directory itself.

This is arguably the most important defense mechanism because ACLs and security mechanisms on software (layer 7) will sometimes fall short protecting the network because of the extreme complexity of communication up in this layer. by default only the 1st MAC address will be register - so we need to know the below information. can you check what MAC address that is in the Logs find out what port associated with and try to clear table for that entry and check. One of the security features available with Cisco switches (among other vendors) is switchport security. Some are Cisco security features that eliminate several important attack vectors on layer 2. This may be the reason the MAC address table somewhere still exiting in the switch as per the information. When configuring the security for a network, it is important to take advantage of the security features of all deployed devices. aging-time Set MAC address table entry maximum age dynamic. Aging Time : 0 mins Aging Type : Absolute SecureStatic Address Aging. ALSwitch(config-if)switchport port-security mac-address sticky. Cisco switches (running IOS) have plenty of features that are critical to modern networks. switchport port-security mac-address sticky, This command is executed in interface.
