We have couple of Cisco IP Phone 7985 deployed. We have noticed the following logs:
%SYS-4-P2_WARN: 1/Invalid traffic from multicast source address 35:4f:81:00:00:63 on port 6/29
Understand that source ip address should never be multicast. We have seem the above log appearing in switchport when the Cisco IP Phone 7985 is attached.
Also, the usual multicast should start with 01:00:5e and our case it start with
Can anyone advise? Is there a concern on this.
