I have a SX1016 pair configured as an MLAG pair that I have connected to my Cisco 6509 VSS. I followed document linked below. We seem to be experiencing some strange behavior when attempting to access various hosts connected to the SX1016 MLAG pair - strange in that we cannot access some hosts while others on the same VLAN are accessible.
I would like to know if there are different/other setup requirements needed for connecting to a VSS based system.
