     In master mode, all SSG functionality is available. In backup mode, SSG works only as a bridge in_dev <-> out_dev, no packets are emitted by SSG itself. It is supposed that in backup mode no traffic should come to SSG at all. But it seems that some service L2 protocols necessary for the operator's network may still arrive at the SSG in backup mode, which is why the transparent bridge mode remains enabled in backup mode. In master mode, all SSG functionality is available.
