These MAC addresses are stored in the address table and in the running configuration of the switch. Static secure MAC addresses – configured manually with switchport port-security mac- address mac- address. When you enter this command, the interface converts all the dynamic secure MAC addresses, including those that were dynamically learned before sticky learning was enabled, to sticky secure MAC addresses. To enable sticky learning, enter the switchport port-security mac- address sticky command. Simply so, how do I create a sticky MAC address? Massimiliano Sbaraglia SWITCHING ARCHITECTURES DESIGN MODELS vlans. They are learned dynamically from the devices connected to the switchport, are put into the address table AND are entered into the running configuration as a static secure MAC address (sometimes referred to as a static sticky MAC address). What is sticky address learning? Sticky – Sticky secure MAC addresses are a hybrid. Allowing the port to continuously learn MAC addresses is a security risk. Sticky MAC is a port security feature that dynamically learns MAC addresses on an interface and retains the MAC information in case the Mobility Access Switch reboots. Note that DHCP snooping will not likely work because MAC is not learnt.

Host connected to it can reach out to anything beyond this ASIC if it is provided with a Static IP address. Communication to and from the port is not broken. Run this command to enable the switch port:Ĭorrespondingly, what is a sticky MAC address? Description (partial) Symptom: MAC address is not learnt dynamically on the Asic-0 Ports of a 3850 Switch Stack. After removing the offending MAC address the switch port link goes down.wheremac_addressis the MAC address that you want to delete. Run the command: Router(config-if)# no switchport port-security mac-address mac_address.
