Here, firstly, we will enable Port Security under the interface GigabitEthernet0/0/1. Port Security with Protect Action ShutdownĪt the beginning, only two PCs wil be connected to the hub. Now, let’s configure all these steps one by one. – There will be No error about Protection Action. – We will set Port Security Protection Action as “Protect”. – We will delete the link between PC4 and the switch, again. After that, we will check Protection action “Protect”. – We will check MAC table, ant there will be no PC4 there.Ĥ. – There will be an error about Protection Action. – We will set Port Security Protection Action as “Restrict”. – We will delete the link between PC4 and the switch. Then, we will check Protection action “Restrict”. – And in the MAC Table, there will be no PC4 as expected.ģ. – There will be an error after this addition and our port will be shutdown. – We will check MAC Table and see PC3 on the mac table. – We will set Port Security Protection Action as “Shutdown”,

Firstly, we will check Protection action “Shutdown”. – We will define Violation (prtotection) actionĢ. – We will set dynamic MAC address learn (sticky), – We will define maximum allowed MAC address on that port, We will configure switch’s Gigabitethernet 0/0/1 interface for Port Security. Only ports which have a device connected and active will show the mac address detail.Our Huawei Port Security Configuration steps will be like below:ġ. With the above command, one can figure out which Mac address is on which port of catalyst switch. Switch# show mac-address-table | include 0009.aabb.06e9 Or if you know the mac address and want to know which port the mac address is coming from, use the following command Switch# show mac-address-table | include Fa0/5 If you know the switch port you can use the following command Only ports which have the device connected and active will show the mac address detail. mac address of the connected device) and port number. The mac address or CAM table shows the Vlan associated with the port, MAC being learned on the port (i.e. With the command, you can figure out which MAC address is on which port. Total Mac Addresses for this criterion: 5 The below command helps to view which port the cisco show MAC address is being learned from. At times, network and IT admins are faced with the challenge to find out which device is connected to which port of the catalyst Switch or which port of the switch is a specific device mac address coming from.
