C7000 OA VLAN Tagging not functioning

[Chad E.]

I have requested 802.1Q trunks for my OA uplink, here are the port assignments:
!
interface GigabitEthernet0/7
description GE 15-Enc1 OA1
switchport trunk encapsulation dot1q
switchport trunk native vlan X
switchport trunk allowed vlan Y
switchport mode trunk
switchport nonegotiate
speed 100
duplex full
!
interface GigabitEthernet0/8
description GE 15-Enc2 OA1
switchport trunk encapsulation dot1q
switchport trunk native vlan X
switchport trunk allowed vlan Y
switchport mode trunk
switchport nonegotiate
speed 100
duplex full

I have enabled VLAN Mode enabled, defined the 2 VLAN's above and have set X as the default. Afterwards, the OA is not reachable as assigned.

Figured it out...network team needed to set the allowed VLAN line as such:

switchport trunk allowed vlan X,Y

Once that as added, the OA's, VC's and iLO began communicating as expected.
