    I am facing issue when switch port is in trunk mode, Aruba AP is not getting registered on Controller. Appreciate your support on below.

    I have Aruba Controller 7210 with AP 655. Controller is acting as DHCP server (option 43 and 60) for AP 655.

    IP helper address is configured on VLAN 2500 for Controller VIP.

    Note: VLAN 2500 is not configured on Controller.

    When Aruba 655 AP is connected with switch port 4 is in access mode, AP 655 is registered on controller. 

    AP 655 E0 Port is connected with Huawei Switch Port 4: (AP get registered to Controller)

    Switch> port default vlan 2500

    Switch> stp edged-port enable

    When Aruba 655 AP is connected with switch port 19 in trunk mode. AP 655 is not getting registered on controller. 

    AP 655 E0 Port is connected with Switch Port 19: (AP not getting registered to Controller)

    Switch> port link-type trunk

    Switch> port trunk pvid vlan 2500

    Switch> port trunk allow-pass vlan 500

    I'm not familiar with those switches, but found with a search that you should put your native (primary) VLAN also in the allowed VLAN list:

    The port trunk pvid vlan command only specifies the default VLAN of a trunk interface but does not add the trunk interface to the default VLAN. A trunk interface forwards frames with the default VLAN ID only after it is added to the default VLAN using the port trunk allow-pass vlan command.

    So, port trunk allow-pass vlan 500,2500 may do the job...

    .. which is not uncommon across some other switch vendors.

    Hi Herman 

    thanks for your input. I tried below configuration but it didn't work. Appreciate if you can look into it and share your feedback.

    When Aruba 655 AP is connected with switch port in trunk mode. AP 655 is not getting registered on controller. 

    ==================================================================================================

    Aruba 7210 Controller VIP is configured as IP helper address on Router. 

    VLAN 2500 not configured on Aruba Controller. 

    Aruba 7210 Controller is acting as DHCP for AP through option 43 and 60.

    WLC Management VLAN= 200

    AP Management VLAN = 2500 (Aruba Controller VIP configured as IP helper address under this vlan)

    Bridge Mode SSID VLAN = 500

    ====================================================================================================

    Switch Port Configuration:

    Switch> port link-type trunk

    Switch> port trunk pvid vlan 200

    Switch> port trunk allow-pass vlan 200 500 2500

    How are you configuring a DHCP pool on the controller for a VLAN that isn't configured?  Or even a VRRP instance?

    I don't know those switches, but if the AP connects to the controller if you have an access port in VLAN200, but not if you switch to a trunk port with native VLAN 200, then I'd think the issue lies in the switch (config). Personally I would run a port mirror on the port connecting to see if traffic runs in the correct tagged VLANs and native (untagged).

    You may work with your network partner for the switches or APs to do that analysis as it's hard to tell where the problem is from a distance (and on switches that I don't know).
