In some customer's cases, third-party wireless APs are able to be powered up by PoE but their MAC addresses cannot be learned on switch ports.
There are no issues with Cisco switches for the same model of APs.
Third-party APs (such as Extreme) can be powered up by PoE and LLDP neighbor information is being detected as normal.

Cause of issue is that there are no "untagged" VLANs configured on the switch port ge-0/0/21. However, third-party APs needs to be honored in a native VLAN (untagged VLAN) so that their MAC addresses can be learned in MAC table.

*** After adding "set interfaces ge-0/0/21 native-vlan-id 1" on the switch/VC (to align with customer's Cisco core switch), MAC address of the AP is being learned.
*** Please add the same native VLAN ID on the uplink interface otherwise communication between the core switch/gateway and AP still fails.
