# Revision history [back]

My Neutron policy.json file contains this line:

"update_port:mac_address": "rule:admin_only or rule:context_is_advsvc"


This means that one has to be admin to change the MAC address, or have the advsvc role (that's what the second rule boils down to).

• remove the two rules from the policy, so that it looks like this: "update_port:mac_address": "", then try again
