port authentication methods

[tedauction]

Hello, regarding switchport port-security, the normal method is to allow based on MAC address.

I understand you can also use RADIUS 802.1x for this purpose.

My question is, is there any other form of port access authentication that can be used apart from these two ?

Thank you.

Hi

Those are the 2 possibilities to secure ports.

However, port security isn't a reliable method.

Within dot1x, you have several methods:

- MAC

- user/password

- certificate

- and web authentication even if it isn't used a lot for wired.

Thanks

Hello Francesco, thank you.

Why do you say 'port security isn't a reliable method' ?

Thank you.

Because it's based on Mac address and this is something that you can spoof very easily.
