Like this....

interface GigabitEthernet1/0/21
 description AAPT Trunk
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 215-218,320,321,398
 switchport mode trunk
 load-interval 30

interface GigabitEthernet1/0/213208
  description AAPT Trunk:320:8
  encapsulation dot1Q 320 second-dot1q 8
  ip address x.x.x.x 255.255.255.252

interface GigabitEthernet1/0/2132091
