Configure SPAN on Nexus 5K

We are implimenting the Sniffer infinistream from NetScout on our core routers. These routers are connected to the NEXUS 5K/2K switches and we need help in port mirroring. we had this on the Nortel passport switches and now they are replaced with the Nexus. The two reduandant routers connected to two diffrent WAN links and two Nexus 5k/2k which are in turn connected to the core switches (two 6506 running VSS). here is the intended config:

On Nexus-1
conf t
interface eth107/1/12
switchport monitor
exit
monitor session 2
description monitoring CE17A
destination interface eth107/1/12
source interface eth107/1/11
exit


On Nexus-2:

conf t
interface eth122/1/12
switchport monitor
exit
monitor session 3
description monitoring CE16A
destination interface eth122/1/12
source interface eth122/1/11
exit


Could someone please verify and let me know that there are no issues with this? I am just looking for a validation being a newbie on Cisco.

Thanks

Mehul.

Its my understanding that you can configure FEX ports as SOURCE ports only, not SPAN port destinations... That will have to be done on the 5K ports directly.
