Is your VLAN 400 configured as remote SPAN vlan? Also, you don't need to put
fa0/16 on second switch into vlan 51. Other than that everything else looks
good.
My working example is this:
SwitchA:
vlan 500
remote-span
monitor session 1 source interface fa0/1 both
monitor session 1 destination remote vlan 500 reflector-port fa0/20
SwitchB:
monitor session 1 source remote vlan 500
monitor session 1 destination interface fa0/10
This will let you see the traffic on SwitchA fa0/1 while having sniffer
connected to port fa0/10 on SwitchB.
