The switch will send it out all ports except the one it received the frame from. This isn't a problem except if you start to introduce physical loops into your network to provide resiliency against a link failure, you can get a BUM frame spinning around the network. Unlike IP there is no TTL that decreases and eventually hits zero and gets dropped, that guy is there until something breaks the path. Spanning Tree protocol is a mechanism to detect and deterministically break the loop by blocking a link.
