Nevermind , now it working fine
I've configured it in another way:
set policy-options prefix-list manager-ip
set policy-options prefix-list SW-ADMIN x.x.x.x/32
set interfaces lo0 unit 0 family inet filter input SW_Protection
set firewall family inet filter SW_Protection term ALLOW-MNG from source-prefix-list SW-ADMIN
set firewall family inet filter SW_Protection term ALLOW-MNG then accept
set firewall family inet filter SW_Protection term BLOCK-MNG from destination-address x.x.x.x/32
set firewall family inet filter SW_Protection term BLOCK-MNG from destination-port ssh
set firewall family inet filter SW_Protection term BLOCK-MNG from destination-port telnet
set firewall family inet filter SW_Protection term BLOCK-MNG from destination-port http
set firewall family inet filter SW_Protection term BLOCK-MNG then discard
set firewall family inet filter SW_Protection term ALLOW-REST then accept
I don't know why from the first example it did not work .. but hey, now it is working by this way
