[ale] KVM and Cisco

[Chuck Payne]

Brain thank, I was thinking it might be trunk. Trunk would be best? I only
ask because I found this right before your e-mail.

Maximum MAC Addresses: 1

I read that would cause issues and shut down the port. So I tried

config t
inter Gi0/39
switchport port-security maximum 25

Maximum MAC Addresses      : 25

Now I can ping my from my guest

But if I have more than 132 hosts, the arp table could fill it up, correct.
So trunk would be best.
