Is there a method to config static-mapping address quickly??

I configed a dhcp server in the vyos,and now I want to add some static-mapping address,
i know the config command in the manual:

service dhcp‐server shared‐network‐name <name> subnet <ipv4net> static‐mapping <mapname> ip‐address <ipv4> service dhcp‐server shared‐network‐name <name> subnet <ipv4net> static‐mapping <mapname> mac‐address <mac>
but I have more than 50 computer,it’s hard to config them one by one,
is there a method to do this quickly??

ps: I tried to modify “/etc/dhcp3/dhcpd.conf” file,but it doesn’t work.

If you have list of macs and needed ips, you just can generate set of commands from script

Thanks for you,
and yes ,I can get the macs and the IP-address,
but how to run the script?? In the configure mode?

I write a simple script to test,and it is failed,
the script is:

configure show

the file name is t.sh
when i run:

sh t.sh

It says:

[code]vyatta@vyatta:~$ sh t.sh

Invalid command: show [t.sh]
[/code]

ok, I find it.
the correct command is “source”
