Hi,
Here is my VLAN and port mode to the aruba switch: 
And here is my aruba config:
trunk 24 trk1 trunk
!
interface 24
name "TRUNK TO ROUTER"
exit
!
vlan 40
name "MGMT"
tagged Trk1-Trk4
ip address 172.16.17.2 255.255.255.0
exit
Untill now i cant ping to vlan 40 on aruba and i cant ping to inside network.
Could someone verify my aruba config?
Thanks
