Hi Alaa

do u wanna set static mac or static arp ?

if you wanna set static mac you should deploy your firewall as transparent mode.

you can refer to this KB

http://kb.juniper.net/index?page=content&id=KB6120&actp=search&searchid=1251048406434

-------

The 'set MAC' command sets a static MAC address per interface to the MAC learning table of the Juniper Firewall NetScreen device. This command is only available on NetScreen devices in transparent mode. If the NetScreen is in NAT or Route mode, the 'set MAC' command will not take any effect. There is no way to change the MAC address of the physical interface itself.

-------

but if you wanna set static arp, this command like below 

set arp <IP address> <Mac> <interface>

Thanks

You can check if your box is in NAT/route or transparent mode with CLI "get sys | i System"
