C9300 - App-Hosting with RSPAN VLAN + Mirror Interface

[lauresfrank]

Hi,

I use Cat9300 with App-Hosting Wireshark in conjunction with RSPAN VLANs as capture destination.

!
app-hosting appid c9kwireshark
 app-vnic AppGigabitEthernet trunk
  vlan 999 guest-interface 1
   mirroring
  vlan 101 guest-interface 0
   guest-ipaddress 10.1.1.9 netmask 255.255.255.0
 app-default-gateway 10.1.1.3 guest-interface 0
 app-resource docker
 app-resource profile custom
  cpu 7400
  memory 2048
  persist-disk 1024
  vcpu 2
!
vlan 999
remote-span
!
interface AppGigabitEthernet1/0/1
switchport mode trunk
switchport trunk allowed vlan 101,999
!
monitor session 1 source interface Po1 
monitor session 1 destination remote vlan 999
!

Unfortunately I cannot see any traffic on guest-interface1 coming from PO1 redirfected into vlan999. Can anyone explain why or what the missing piece is? Is RSPAN supported by App-Hosting Bridge or anything to consider?

Thank you.
