The unexpected packet is probably an IP broadcast packet (like RIP)
generated by the cisco's secondary IP address. Because the
workstation believes it is only attached to a single subnet (your
primary cisco subnet), it gets confused when it receives a packet
from a node on the secondary subnet.
I don't know of any workaround, because secondary subnets would seem
to be "bending the rules" anyway...
