RSPAN question

Hello All,

I have a need to setup RSPAN and looking to see how to sniff.

Sw1=======Sw2

Vlans per Switch
SW1 => vlan 65,66,67,68,69,70, 999
SW2 => vlan 65,66,67,68,69,70, 999
SW1 and SW2 are 3750

I have a sniffer drop at SW2 1/0/43 and need to sniff all the vlans at both
the switches to this port.

Configuration below can only brings the source vlan 65,66,67,68,69,70 on SW1
to SW2 port 1/0/43 .

Problem is Traffic from SW2 vlans (65,66,..70) are not sniffed to sniffer
port through configuration 1.
- Switch doesnot allow to add additional source commands like "source vlan
or source interface".

I havenot tried the configuration option2 below. Would this work or Any
other method to solve this ?

Configuration 1:
-------------------------
SW1:
-------
vlan 999
 rspan

monitor session 1 source vlan 65 - 72
monitor session 1 destination remote vlan 999

SW2:
--------
vlan 999
 rspan

monitor session 1 source remote vlan 999
monitor session 1 destination interface Gi1/0/43

Configuration 2:
-------------------------
SW1:
-------
vlan 999
 rspan

monitor session 1 source vlan 65 - 72
monitor session 1 destination remote vlan 999

SW2:
--------
vlan 999
 rspan

monitor session 1 source remote vlan 999
monitor session 1 destination interface Gi1/0/43

monitor session 2 source vlan 65 - 72
monitor session 2 destination remote vlan 999
