How setup dhcp in zone:

Create zone config for dhcp-zone:

sudo cat > dhcp.cmd <<EOT
create -b
set zonepath=/zones/dhcp
set brand=dpkg
set autoboot=false
set ip-type=exclusive
add fs
set dir="/export/home/admin"
set special="/export/home/admin"
set type="lofs"
end
add fs
set dir="/export/builds"
set special="/export/builds"
set type="lofs"
end
add net
set physical="iz1"
set global-nic="vsw0"
add property (name=ip,value="192.168.0.1")
add property (name=netmask,value="255.255.255.0")
add property (name=gateway,value="192.168.0.254")
add property (name=primary,value="true")
end
add attr
set name="resolvers"
set type="string"
set value="8.8.8.8"
end
verify
