Hi
I am having three switches. My Sniffer is connected with my Core Switche port 11.
I am having 1 core SW, 2 Access SW.
CoreSW --------------Trunk--------------->AccessSw1-----------------Trunk-------------------------AccessSw2.
I am trying to configure Monitor session between AccessSW2 and Core SW.
my configuration ar Core SW
monitor session 1 destination interface Fa0/11
monitor session 1 source remote vlan 901
At AssessSw2
monitor session 1 source interface Fa0/1 - 22
monitor session 1 destination remote vlan 901
these configurations work fine if I ommit AccessSw1.
So what Configuration I need at AccessSW1 to communicate fine. Please help me on this..

Have you created vlan 901 on access switch 1 ?

no . I did not creat any Vlan 901. If I need to creat then should it be remote Vlan or not?
Do I need to add monitor session command there?

You need vlan 901 on all intermediate switches so just add the vlan to the vlan database ie.
access1(config)# vlan 901 name v901
you don't need to configure any monitor commands on the intermediate switch.

bumping up the old post, however - do we need to specify a vlan 901 as remote-vlan on SW2?
Or just creating vlan901 should be enough?
What would happen if we add "remote-vlan" command into vlan901 config os SW2?
Thanks.

Alexander,
You will have to specify the remote vlan on Sw2, just creating it won't help. Following is the config for the SW2.
Switch(config)# monitor session 1 source remote vlan 901
Switch(config)# monitor session 1 destination interface fastEthernet0/5
The commands are a bit platform specific, as they are a bit different for the 6500 switches:
For SW2 on Cisco6500
Router(config)# monitor session 1 type rspan-destination
Router(config-rspan-dst)# source remote vlan 2
Router(config-rspan-dst)# destination interface gigabitethernet 1/2
Thanks
Ankur
