Yes, it should support RSPAN. What is the IOS you are running. Please paste the show version from the switch.

can you please give me the version of iOS that support Rspan, and how i check in my switch that it support rspan

I don't think your IOS supports rspan. From the config doc for your IOS they only talk about span:-

It looks like you need 12.1(20)EW as a minimum. The best thing to do is check on software advisor which is a Cisco tool

i checked it on the software advisor bu it give the following nessege:

Remote SPAN (RSPAN) Support for source and destination SPAN ports located on other compatible switches

for your knowledge the 4006 consist supIII engine
