Prime 3.1 after upgrade to 3.1.7 shows "Default trunk allowed are 1, 1002-1005"

[Worko]

I upgraded the customer's Prime infrastructure from 3.1.5 device pack 12 to 3.1.7 device pack 15. He complains that ever since this happened, he sees folllowing statement in the "Interfaces" group of the "Switches and Hubs"- "Configuration" pane:

"Default trunk allowed are 1, 1002-1005. If the device go down, check the vlan configuration." 

Is it a bug or does it something relevant say to me?

Thanx

Is the affected devices newly supported by DP 13, 14 or 15? If yes, try to remove it from PI and add it again, maybe it's hasn't the correct configuration synced.
