How to limit mac-addresses on switch

Answered Question
Dec 9th, 2008

We have 2 different lans..one user

has a hub connected to one switchport..he need 3 network connections for vlan 5. This would give him unlimited network access which is what we want.

However..2 users have patched into that hub ..and they have un fettered access.

What security command would i use

to allow 3 macs but not that final 2?

I have this problem too.

You would need to implement port security. If you want just the 3 addresses, I would recommend that you hard code them in:

switchport port-security

switchport port-security max 3

switchport port-security mac-address

switchport port-security mac-address

switchport port-security mac-address
