Can i add it to the Management VLAN instead of the Lo0 ?
For example:
set interfaces vlan unit 1 family inet filter input local_acl
set interfaces vlan unit 1 family inet address 10.155.96.5/21
user@myhost# set vlan unit 1 family inet filter input local_acl
set interfaces vlan unit 1 family inet address 10.155.96.5/21
