Blake, It looks like there is a setting on the port that if it see more than one mac address it won't sent. I found the setting and updated
config t inter Gi0/39 switchport port-security maximum 25 show port-security inter Gi0/39 Port Security : Enabled Port Status : Secure-up Violation Mode : Restrict Aging Time : 2 mins Aging Type : Inactivity SecureStatic Address Aging : Disabled Maximum MAC Addresses : 25 Total MAC Addresses : 0 Configured MAC Addresses : 0 Sticky MAC Addresses : 0 Last Source Address:Vlan : 0000.0000.0000:0 Security Violation Count : 0 This fixes, but I think I might need to set the port to a trunk. As far as STP, we only turn it on to see it would help. It's off. Yea, we bought in a Cisco Guy who want to spend 60K and rebuild the network up from the ground. I tried to explain to him, can't. So I am slowly learning. I will never be CCNA but at least I can do some things. Thank you for your help.
