Description (partial)

Currently VLAN IDs are not recycled or re-used. When an IP address pool is disassociated from a virtual network (VN) and reassociated back to the same VN for updating the authentication policy name or group policy (SGT), the old VLAN ID will be removed and a new VLAN ID is assigned. This leads to reconfiguring trunked server or layer 2 switches on the fabric

This is observed when disassociating an IP address pool from a VN, and reassociating the IP address pool to the same VN (without any other operation in between).
