It is also known as a physical or hardware address.

MAC Address or media access control address is a unique ID assigned to network interface cards (NICs). All this information is useful if you want to verify the generated mac address with the original vendor of this device in OUI vendor database. Finding the mac address from this database tells us which manufacturer originally manufactured this device and what is the prefix, postfix of a given mac address, moreover it tells us what country was this device manufactured. The MAC Address vendor database consists of a list of mac addresses of all devices manufactured till date. If you do not port security will shutdown traffic to both MACs on that port.MAC Address Lookup Tool searches your MAC Address or OUI in mac address vendor database. If you have a computer that is running a VM and the VM is configured to connect to the network via bridged mode, then you must also include the MAC of the VM in your port security configuration on the physical port that the host is connected to. You will need to specify which MAC addresses are permitted for each port that you are enabling port security on. If you are plugging an unmanaged switch into a port that you are using port security on (not recommended) then you need to allow the MAC address of each device that will be connected to that unmanaged switch. I need to stop and emphasize a point here. Set Max Allowed Statically Locked Mac to the number of MAC addresses that will be connected to this port.

Set Max Allowed Dynamically Learned MAC to 0 (according to the manual this effectively disables dynamically learning MAC addresses).Select Enable in the Port Security field.Select the ports you want to enable port security on.Specifically the steps to do this are provided on page 221. You said you want "to activate port security on specific ports to allow only one specific device (MAC) on this port."

I went through the Netgear GS752TXS Software Administration Manual and what you are looking for is on pages 220-223. I really would like to have ports to accept just specific MACs and some ports to support multiple ports (like meeting rooms etc).ĭoes anybody know if thats possible with this device?Īnother good thing would be the possibility to specify a list of allowed MAC addresses all over the switch and block all other. the port won´t accept another MAC/device.īUT the device also cannot be plugged in into another port! It´s limited to this specific port.
The problem with "static assignment": If you assign a MAC address to the port statically, it works in first line.

Since if somebody plugs in his device in another port the "locked" port is free for reassignment :-(
So limiting the dynamic entries on a specific port to "1" does not help here. The problem with dynamically learned adressing is that all dynamic entries are aging (default 300s - then they are renewed or lost) AND if you plug in a device into another port, the entry is also updated to the other port and the entry of the old port is lost. It´s possible to prevent somebody to plug in a switch in between - buts thats it. Lock dynamically learned makes nearly no sense.
If I activate port security, I have to options: lock down the number of dynamically learned addresses - or the number of statically learned adresses.
That´s what I understand from "port security" here and should be possible with this device - according to the documentation. I would like to activate port security on specific ports to allow only one specific device (MAC) on this port. Has anybody here has in use the Netgear GS752TXS (52 Port Stackable Smart Switch with 10GE uplink) with port security active?
