Why am I getting multicast traffic on a switch port connected to printer.?
Switch port is also having storm control setting enabled.
interface FastEthernet3/0/19
switchport access vlan 113
switchport port-security aging time 1
switchport port-security violation restrict
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
auto qos voip trust
no mdix auto
storm-control broadcast level 50.00
storm-control multicast level 50.00
no cdp enable
spanning-tree portfast
spanning-tree bpduguard enable
service-policy input Scavenger
end

Certain Printers have discovery feature which sends multicast. Network Scanning etc etc.
Thats the reason you are seeing multicast packets in there.
