RSPAN cisco + hp procurve 6120xg

[maxim315]

hi

I need a copy internet trafic.
Have a such network topology from Cisco to VM:

2960 - 3750 - cisco 3120 -

                                                                               - VMWare dSwitch - vNic VM

                          - hp procurve 6120xg -

//RSPAN on the 2960 
 
vlan 61 
 remote-vlan 

 interface FastEthernet0/2 
  description ===== Internet-inside ===== 
  switchport access vlan 950 
  switchport mode access 

//this port connected to the 3750. 

interface FastEthernet0/12 
  description ===== SPAN_INET ===== 
  switchport trunk allowed vlan 61 
  switchport mode trunk 
 
//this port is also connected to the 3750. 

monitor session 1 source interface Fa0/2 
monitor session 1 destination remote vlan 61 


3750: 
//different vtp domain

vlan 61 
remote-vlan 

 interface GigabitEthernet2/0/3 
  description ===== Internet ===== 
  switchport access vlan 193
 switchport mode access 
 
//port fa0/2 from 2960 with Internet-traffic. 

interface GigabitEthernet3/0/10 
  description ===== SPAN_INET ===== 
  switchport trunk encapsulation dot1q 
  switchport trunk allowed vlan 61 
  switchport mode trunk 

//port fa0/2 from 2960 with copy Internet-traffic.

interface TenGigabitEthernet3/0/1
 description ===== BLADE_TRUNK_MEMBER 6120s09 =====
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 500
 switchport trunk allowed vlan 1,2,4,5,7,50,51,60-62
 switchport mode trunk
 switchport nonegotiate

//trunk to the hp 6120xg

on the hp procurve 6120xg:
vlan 61 
    name "SPAN" 
    tagged 1-16,22 
    no ip address 
    exit 
//1-16 ports - is a host's, 22- trunk to the 3750

I did some research and figured out that if Vm is on the physical host behind hp procurve blade switch 6120xg - no mirrored trafic at all. Although if Vm is on the physical host behind Cisco blade switch - have mirrored traffic on VM vNIC.  I've checked out with wireshark on Windows OS.

Is smth wrong with 6120xg tagging? Maybe 6120xg somehow wiping original vlan of frame... 

No problem with CIsco blade switch.
