We are seeing an issue on one of our Ethernet switches(Juniper QFX3500) .Ports were shared across the team and each member is complaining that on their captures they are seeing the traffic not intended to them. Further checking the mac table we identified that destination macs were not discovered by the switch and there is an entry i guess that is causing the issue which is shown below.In this case will all (for which dest mac were not discovered) fell in the category of unknown unicast and causing the flooding?

One Answer:
Yes, switches will flood traffic to all ports in the vlan if the destination mac-address was not seen as a source yet. See also the answers to this question... answered 26 Jun '13, 15:47  SYN-bit ♦♦ |
