I created a bridge and assigned a physical interface to it as a slave. Now both have the same MAC and IP addresses. I thought only the master would have an IP address. Is something wrong ?

Nothing is wrong. The slave cannot have MAC and IP addresses of its own because it inherits the master's MAC and IP addresses.
