Securing your network using MAC Addresses
Posted on 2005-04-18
All, this is a security/switch question so I came to this forum first
I have a problem with people just coming into our offices and plugging there laptops in without asking...:-| Im not best pleased with this but how do I remedy this?
My thoughts are to create a backbone using a layer 3 switch (we have 1 Cisco catalyst switch that we can use) and then create VLANS off of this onto our current switches (this is a seprate idea in that I want to *subnet* certain depts and remote users) ... anyway, my question is can I configure the Cisco switch to accept ONLY certain MAC addreseses? I know I have to build a list of all MAC addresses in the company, however Id rather this than take the chance of someone letting loose a virus just cos we have no *internal* security as such....
Anyone any thoughts on whether this is possible
