FREERADIUS - show VLAN in radacct's NAS-PORT-ID column

IN A tEST lab, We are using an old box with FreeRADIUS Version 2.2.8 along with Mikrotik routerboard (v6.43.3) as NAS. Vlans are properly configured. users connect via pppoe service. Each Vlan has pppoe server assigned. in Radacct "nas-port-id" column, how can we show VLAN name or Vlan number instead of just numbers. currently in radacct we can see this NAS-PORT-ID column: 1548484 NAS-PORT-ID column: 1529618 at another network I can saw the VLAN names there, like NAS-PORT-ID column: Vlan11 NAS-PORT-ID column: vlan20 is there any additional config required on freeradius to achieve this ?
