Is there some MAC address value, that can be used to denote that device does not have MAC set (something like 0.0.0.0 for IP).? I thought of ff:ff:ff:ff:ff:ff, but afraid that it could be meaningful when set for interface.
The question is how to state the fact that specific interface does/should not have MAC - if i cannot just leave the field empty (in docs, such a restriction) what value should I use.? For ip i can specify 0.0.0.0 for that purpose.
Lets take the following TR-098 parameter:
- its value is required to be either empty (n case of PPPoA) or contain mac of underlying device (if PPPoE).
But in my case empty value cannot be specified - i have to give some MAC.
