下面配置命令中的“$data_VLAN、$trunk_VLANs和$native_VLAN”是什么意思，代表什么vlan？
“macro name setup-access
# macro keywords $data_VLAN
switchport mode access
switchport access vlan $data_VLAN
@
!
macro name setup-trunk
# macro keywords $trunk_VLANs
# macro keywords $native_VLAN
switchport mode trunk
switchport trunk allowed vlan $trunk_VLANs
switchport trunk native vlan $native_VLAN”
