troubleshooting - odd cisco behaviour - daisy chained

mlsw1 -> sw1 -> sw2 -> sw3

all switches can ping each other except mlsw1 and sw2 ... sw2 can send a ping to the broadcast ip and receive a response from mlsw1 --- but mlsw1 sending a ping to broadcast ip does not get a response from sw2.

spanning tree shows the correct root ports leading from sw2 up to mlsw1 ...

thoughts?
