They mention several threats that I thought I would protect my network against. I have a few questions for anybody who can answer them.
1. They mention using port security to prevent a mac flood. Problem is, that on my 6513 it says that it can only learn 1024 mac addresses when I apply port security. This is not enough for the "specified" 3 per port when using IP phones. Any idea how to get around that?
2. The document mentions to turn off native vlans to prevent a "nested vlan" attack. Problem is that when I turn of native vlan's for my Aironet 1200 AP's they stop passing traffic. Also, on my other trunk links - it just makes the native vlan = vlan 1. Isn't that a bigger threat?
3. On that note - how do I change the management VLAN to be something OTHER than 1?
THANKS to anybody who can answer either all or part of my concerns.
