The delay in seconds that the SEB waits before transitioning to the next port state. The forward delay should be large enough to allow all Super ELAN bridges in the SuperELAN to disable ports in the new topology while the new spanning tree is being set up prior to forwarding data frames. Values too low might cause temporary loops in the SuperELAN, because not all bridges will complete the spanning tree updates. While values too large, lengthen network partitions after the spanning tree has converged, which causes data frame delays. The default value indicated that the bridge will begin forwarding frames 30 seconds after the spanning tree has converged: 15 seconds in listening state and 15 seconds in learning state.
