Re: Layer 2 port security

to limit the number of mac address that can connect to L2 port use the following command

switchport mode access

switchport port-security maximum 2

switchport port-security mac-address sticky

this config will allow only two mac connect to the port if more it will do what action u put in the vaulation action

sticky mean the port will take the mac address from the connected device dirctly to put it in the table

first two will be rigistered u dont need to put it manuly

u can also use dot1x for L2 authentication with username and pass

aslo if u wanna make dhcp security u can use DHCP snooping

also Secure the Layer 2 spanning tree topology with BPDU guard

good luck
