arp collision on Cisco ASA from Airport Extreme and AppleTV
My Cisco ASA-5515-x is reporting ARP collisions between my Airport Extreme and my AppleTVs
(cisco log) ARP request collision from 192.168.1.167/3412.9800.935d on interface Inside with existing ARP entry 192.168.1.167/18b4.3033.d197
(cisco log) ARP request collision from 192.168.1.100/3412.9800.935d on interface Inside with existing ARP entry 192.168.1.100/7073.cbe2.87db
(cisco log) ARP request collision from 192.168.1.113/3412.9800.935d on interface Inside with existing ARP entry 192.168.1.113/98d6.bb22.20aa
My DHCP server shows 192.168.1.167 associated with 18b4.3033.d197, .100 with 7073.cbe2.87db, and .113 with 98d6.bb22.20aa
My Airport IP is static using 192.168.1.37.
Its configured in Bridge Mode. It has a hard 1Gig cable to a Cisco 3750 switch. (I actually have 2 Airports in Bridge Mode connected this way. The other is .36 and uses a different SSID but exists on the same 3750 VLAN).
These are happening every 15 seconds or so.
Why would my Airport Extreme be spoofing MAC addresses from my AppleTVs?
